YASK AWA TM.iQp.07 iQpump Controller Programming Manual 7

WARNING

• Read and understand this manual before installing, operating, or servicing this drive. All warnings, cautions, and instructions must be followed. All activity must be performed by qualified personnel. The iQpump drive must be installed according to this manual and local codes.

• Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is on. Do not remove or insert the digital operator while power is on.

• Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm safe level.

• Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged by high voltage.

• The iQpump drive is not suitable for circuits capable of delivering more than 100,000 RMS symmetrical amperes. Install adequate branch short circuit protection per applicable codes. Refer to the specification. Failure to do so may result in equipment damage and/or personal injury.

• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the output of the drive. These devices may generate peak currents that exceed iQpump drive specifications.

• To avoid unnecessary fault displays caused by contactors or output switches placed between iQpump drive and motor, auxiliary contacts must be properly integrated into the control logic circuit.

• YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty. This product must not be modified.

• Verify that the rated voltage of the iQpump drive matches the voltage of the incoming power supply before applying power.

• To meet CE directives, proper line filters and proper installation are required.

• Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be replaced before operation.

• Observe electrostatic discharge procedures when handling circuit cards to prevent ESD damage.

• The equipment may start unexpectedly upon application of power. Clear all personnel from the drive, motor, and machine area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the drive.

• Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

◆ Intended Use

Drives are intended for installation in electrical systems or machinery. For use in the European Union, the installation in machinery and systems must conform to the following product standards of

Introduction

This Section describes the applicability of this manual.

The iQpump (P7U) is a Pulse Width Modulated drive for 3-Phase AC induction motors. This type of drive is also known as an Adjustable Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD, and Inverter.

The iQpump (P7U) is a variable torque AC drive, designed specifically for Simplex and Multiplex pumping applications. The pump applications include Booster Systems, Submersible Deep Well, Fluid Storage Tanks, Metering Pumps, Commercial and Residential Irrigation Systems.

The iQpump (P7U) sets a new benchmark for size, cost, performance, ease-of-use benefits, comprehensive pump, motor protection features, and quality. The iQpump includes numerous built-in features such as H/O/A Operation, Selectable Pump Control Engineering Units, PI Control, Pump Basic Control, Pump Protection, Multi-Pump Control (Lead/Lag), and Pump Messaging Terminology.

The LCD keypad/operator is equipped with Hand/Off/Auto functions, copy feature, and 5 lines of display with 16 characters per line.

Built-in PI and pump-specific functions and parameters allow the operator to setup specific control values for a wide range of applications. The iQpump (P7U) will optimize the pump performance by automatically adjusting the pump controller based on operating conditions of the pump, such as process variable changes and pump protection requirements. The P Group programming parameters are dedicated for pumping applications and help facilitate setup.

The iQpump (P7U) drive offers energy savings by controlling the flow rate and the number of operating pumps on the system. The iQpump (P7U) can be configured using the most popular system control configurations including Simplex, Duplex, and Triplex pumps systems. The iQpump is the master controller with the ability to add additional pumps on-line by controlling the digital I/O to each individual motor starter.

The iQpump (P7U) has an optional feature to replace the motors starters with additional drives for a more precise pump control system.

b1 Sequence

The Sequence Group contains parameters associated with starting and stopping the drive. Parameters involving the Run Command, Speed Reference location, Stopping Method and Hand / Auto changeover are located in this group.

◆ b1-01 Reference (Auto Setpoint) Source Selection

Setting Description

0 Operator - Digital Preset Setpoint d1-01 (factory default) 1 Terminals - Analog Input Terminal A1 (or Terminal A2, see Parameter H3-13) 2 Serial Com - RS-485 Terminals R+, R-, S+ and S3 Option PCB - Option Board connected at 2CN

In order to run the iQpump drive and motor, the iQpump drive must receive a Run command and a Auto Setpoint command. Parameter b1-01 specifies from where the Auto Setpoint is received when in the “Auto” mode. Switching into the “Auto” mode can be done by pressing the AUTO button on the digital operator while the iQpump drive is stopped.

Important: If a Run command is input to the iQpump drive but no corresponding Auto Setpoint is input, the Run indicator on the digital operator will turn on and the STOP indicator on the digital operator will blink.

To configure the iQpump drive to follow the “Hand Reference” set by the digital operator: Use the “Hand” mode by pressing the hand key and set P5-01 = “1: Hand Reference (P5-02)”. The hand reference can then be entered into the P5-02 parameter.

The iQpump drive offers the ability to provide four types of “Auto Setpoint” reference sources. These Auto Setpoint reference sources are determined by the setting of b1-01 and the drive set to “Auto” mode by pressing the Auto key on the digital operation.

Note: Prior to programming, it is recommended to first select the system units (P1-02) and the feedback device, Scaling

(P1-03). P1-03 will automatically scale the iQpump Setpoint.

Example: P1-02 = 1: psi P1-03 = 200, feedback range = 200 psi.

To configure the iQpump drive to follow an “Auto Setpoint” set by the digital operator: Set b1-01 = “0: Operator” (factory default), The Auto Setpoint can then be entered into the U1-01 monitor parameter in the “-DRIVE-” menu.

Figure 1.2

Figure 2. Digital Operator Auto Setpoint

To configure the iQpump drive to follow an “Auto Setpoint” set by the analog input: Set b1-01 = “1: Terminals,” and connect a potentiometer or external signal to the iQpump drive. Refer to Figu re 3. for connection diagram for the setpoint potentiometer.

b1-02 = 0, Operator (factory default).

The iQpump drive comes factory programmed for Start and Stop from the Keypad.

The iQpump drive can be programmed to receiver a Run command from four different inputs: digital operator, terminals, serial communications, or an option PCB.

If the Run command input is determined by the digital operator: Set b1-02 = “0: Operator,” and the HAND and OFF keys will be used to provide the Run command to the iQpump drive.

b1-02 = 1, Terminals

If the Run command input is determined by the external terminals: Set b1-02 = “1: Terminals” and initiate an external Run command by a contact closure between terminals S1 and SN. Refer to Figure 8. for the connection diagram of the external Run command.

Note: To use the external terminals requires the iQpump drive to be set to “Auto” mode by pressing the Auto key.

Select between 2-wire and 3-wire control operation by doing the following:

2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN will be interpreted as a Forward Run command by the drive.

Figure 1.6

Figure 6. 2-Wire Control

3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and S2 become Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward / Reverse input for the iQpump drive. When the Forward / Reverse input is open the iQpump drive will run in the Forward direction and when the input is closed, the iQpump drive will run in the Reverse direction.

In 3-wire operation a momentary closure (> 50mS) of S1 will cause the iQpump drive to run provided that S2 is held closed. The iQpump drive will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization (A1-03 = “3330: 3-Wire Initial”), then terminal S3 becomes the Forward / Reverse input.

Note: Reverse operation is disabled in the iQpump drive; however, in 3-wire control, one of the multi-function digital inputs

needs to be programmed to 0. Otherwise, the 3-wire control will not work.

• Only enabled when all three Run / Stop Control parameters are set to a value greater than zero (P4-18 > 0, P4-19 > 0, and P4-20 > 0).

• Available only when in HAND or LOCAL mode.

• PI control is disabled.

• Will always start off running when a run command is given.

• A stop command, power loss or fault will reset all timers and counters associated with the Run / Stop Control.

• A stop command will result in a stopping method set by parameter b1-03.

• When the “Run” portion of the timer expires, the drive stop using the stopping method set by parameter b1-03.

• When stopped due to the “Run” timer expired, the standard “sleep” message will be displayed on the operator.

• When stopped because the final cycle count has been exceeded, the digital operator will display “Run / Stop Finished”. The display will be cleared when a stop command is given or power is lost.

• If a fault (not auto-restart) occurs during Run / Stop Control, all timers and counters are reset.

• If an auto-restart is in process, under most circumstances the Run / Stop Control will continue to operate. However, if the stop timer expires prior to the auto-restart expiring, the drive will wait until the auto-restart time expires before resuming normal Run / Stop Control.

When this feature is enabled and the drive is given a run command, the drive will run for the time specified in parameter P4-18, then stop for the time specified in parameter P4-19. It will do this the number of times programmed in parameter P4-20. (Refer to parameters P418, P4-19 and P4-20.) The display will show one of two messages if the drive is stopped due to this feature. Run-Stop control cannot be enabled when a multiplex mode (P1-01 > 0).

Timed Run:

If parameter b1-02 is set to 5 “Timed Run”, the timed run feature will be enabled. When “Timed Run” is enabled, Terminal S1 will be a normally open “start” input and Terminal S2 will be a normally closed “stop” input. The drive can be started by either causing a rising edge (open to close) on the S1 digital input when S2 is closed, or both S1 and S2 are closed when power is applied to the drive. The drive will then start running at the HAND frequency reference P5-02 and run for the time specified in parameter P4-18. If the drive needs to be stopped before the P4-18 timer expires, the circuit connected to Terminal S2 can be opened, or the Stop or Off keys on the digital operator can stop the drive. The drive can be re-started by simply causing another rising edge on Terminal S1. There will be no modified display or messages when the drive is stopped due to the Timed Run feature. If the drive is switched into HAND or LOCAL mode, the timed run feature will be disabled.

1. Wire-Break detection for Terminal A2 will be completely disabled during Timed Run control.

2. The pre-charge feature is disabled during Timed Run control.

3. Uses the “Hand” reference as the frequency reference. If P5-01 is set to 1, parameter P5-02 will be used as the reference. If P5-02 is set to 0, Terminal A1 will be used as the reference.

4. The “Not Maintaining Setpoint”, and “Low Feedback” faults are disabled during Timed Run control.

5. The “Loss of Prime” fault (if enabled) will become active when the output frequency comes to within 1 Hz of the frequency reference.

6. The Timed Run Control will take priority over the “Auto Mode Fixed Speed” mode (digital input).

When this feature is enabled, the drive will run at the “Hand” frequency reference for the time specified in parameter P4-18. Timed Run cannot be enabled when in Multiplex Mode (P1-01 > 0). (Refer to parameter P4-18.)

determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.

When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5 Hz) DC current will be injected in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0 Default), to establish the end point of the ramp. DC injection can be used to insure the motor is at zero rpm prior to the iQpump drive shutting off.

Figure 1.14

Figure 14. Deceleration to Stop

The actual deceleration time can be determined by the following formula.

If S-Curve characteristics are specified by the iQpump drive programming, they will add to the total time to stop.

1: Coast to stop: When the Run command is removed, the iQpump drive will turn off its output and the motor will coast (uncontrolled deceleration). The friction of the driven equipment will eventually overcome any residual inertia of the system and the rotation will stop.

Figure 1.15

Figure 15. Coast to Stop

Important: After a stop is initiated, a subsequent Run commands input before the Minimum Baseblock Time (L2-03) has expired, will be ignored.

2: DCInj to Stop: When the Run command is removed, the iQpump drive will Baseblock (turn off its output) for the Minimum Baseblock Time (L2-03). Once the Minimum Baseblock Time has expired, the iQpump drive will inject DC current into the motor windings to lock the motor shaft. The stopping time will be reduced as compared to Coast to Stop. The level of DC Injection current is set by parameter b2-02 (50% Default). The DC Injection brake time is determined by the set value in b2-04 and the output frequency at the time the Run command is removed.

Important: If an overcurrent (OC) fault occurs during DCInj to Stop, lengthen the Minimum Baseblock Time (L2-03) until the fault no longer occurs.

3: Coast w / Timer: When the Run command is removed, the iQpump drive will turn off its output and the motor will coast to a stop. If a Run command is input before time T (operation wait time) expires, the iQpump drive will not run and the Run command will need to be cycled before operation can occur. The time T (operation wait time) is determined by the output frequency when the Run command is removed and the active deceleration time (C1-02).

The DC Braking Group contains parameters associated with the DC injection braking feature. Parameters involving the starting frequency, current level, braking time, and motor pre heat current level are located here.

◆ b2-01 DC Injection Braking Start Frequency

Setting Range: 0.0 ~ 10.0 Hz

Factory Default: 0.5 Hz

Parameter b2-01 sets the output frequency where the iQpump drive begins DC Injection during Ramp to stop in order to lock the rotor of the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.

Parameter b2-01 also determines the output frequency that the iQpump drive must be at or below before a Zero Speed condition is considered true. This affects any digital output configured as a Zero Speed signal (H2-0x = “1: Zero Speed”).

Figure 1.18

DC injection

Figure 18. DC Injection Braking During Stopping

◆ b2-02 DC Injection Braking Current

Setting Range: 0 ~ 100%

Factory Default: 50%

The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to hold the motor shaft. DC Injection current is set in percentage of the iQpump drive rated output current. iQpump drive rated output current is stated on the iQpump drive nameplate.

◆ b2-03 and b2-04 DC Injection Braking Time

Parameter No. Parameter Name

b2-03 DC Injection Braking Time at Start b2-04 DC Injection Braking Time at Stop

Setting Range: 0.00 ~ 10.00 s

Factory Defaults: b2-03 = 0.00 s and b2-04 = 0.50 s

The iQpump drive can be programmed to automatically DC Inject for a predetermined amount of time prior to accelerating to speed (b2-

03) and / or at the end of a Ramp to stop (b2-04). Parameter b2-03 can be used to stop a rotating motor prior to attempting acceleration

(i.e. a wind milling fan). If DC Injection braking at start or Speed Search is not enabled, attempting to drive a spinning motor may cause nuisance tripping.

Parameter b2-04 can be used to resist any residual motion of the load after the deceleration has finished.

Parameter b2-04 also serves the function of affecting the length of time DC Injection to stop (b1-03 = “2: DC Injection to Stop”) will occur.

◆ b2-09 Motor Pre-Heat Current

Setting Range: 0 ~ 100%

Factory Default: 0%

A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and prevent condensation. Parameter b2-09 determines the percentage of the iQpump drive rated output current that will be used for the motor pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions. Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat Input (H1-0x = 60). Check with the motor manufacturer to determine the maximum acceptable current level the motor can withstand when stopped. Be sure not to exceed the motor manufacturers recommended level.

26 YASK AWA TM.iQp.07 iQpump Controller Programming Manual

b3 Speed Search

The Speed Search function allows the iQpump drive to determine the speed of a motor shaft that is being driven by rotational inertia. Speed Search will allow the iQpump drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed without first having to bring it to a complete stop. When a momentary loss of supply power is experienced, the iQpump drive output is turned off. This results in a coasting motor. When power returns, the iQpump drive can determine the speed of the coasting motor and start without requiring it to be brought to minimum speed. Speed Search can be programmed to always be active by setting b3-01 or it can be commanded by remote contact closure by setting a digital input.

There are two forms of Speed Search in the drive, the speed estimation method and the current detection method.

Important: When setting the iQpump drive for remote Speed Search input, via a contact closure, the method of Speed Search is determined by the setting of b3-01. If b3-01 = “0: SpdsrchF Disable” then the remote input will initiate speed estimation method, and if b3-01 = “2: SpdsrchI Disable,” then the remote input will start the current detection method.

Parameters L2-03 and L2-04 also affect the current detection method of Speed Search operation.

◆ b3-01 Speed Search Selection

This parameter is effective only when the iQpump drive is given a new Run command.

Setting Description

0 SpdsrchF Disable 1SpdsrchF Enable 2 SpdsrchI Disable (factory default) 3SpdsrchI Enable

Speed Estimation: Method (b3-01 = 0 or 1) The speed estimation method will calculate the speed using measurements of residual motor fields. The speed estimation version is bi-directional and will determine both the motor speed and direction. To enable speed estimation Speed Search at start, set b3-01 = “1: SpdsrchF Enable”.

Important: If the speed estimation method of Speed Search is to be used, then Auto-tuning must be performed prior to using Speed Search. If the length of cable between the iQpump drive and motor is ever changed after Auto-tuning then Auto-tuning should be performed again

Important: The speed estimation mode cannot be used when there are multiple motors operated by one iQpump drive or the motor is two or more frames smaller than the standard size motor per the iQpump drive capacity.

Current Detection Method (b3-01 = 2 or 3): The current detection method starts searching from a predetermined frequency while monitoring the iQpump drive output current to determine when the rotor speed and the iQpump drive output speed (frequency) match. The current detection version is not bi-directional. To enable current detection Speed Search at start set b3-01 = “3: SpdscrhI enable” and program any digital input equal to Speed Search 1 (H1-0x = 61) or Speed Search 2 (H1-0x = 62). Speed Search 1 will start searching from the max. frequency (E1-04) and ramp down to meet the rotor speed. Speed Search 2 will start searching from the set frequency and ramp down to meet the rotor speed.

Important: If a UV1 fault occurs when current detection Speed Search is attempted, increase the setting of L2-04.

Important: If an OC fault occurs when Speed Search is attempted after power loss recovery, increase the setting of L2-03.

◆ b3-02 Speed Search Deactivation Current

Setting Range: 0 ~ 200% of the iQpump drive rated output current

Factory Default: 120% of the iQpump drive rated output current

When using the current detection method of Speed Search, parameter b3-02 sets the current level that will determine when the search is complete and the rotor and output speeds match. When the output frequency is higher than the actual rotor speed, the slip causes the current to be high. As the output frequency is lowered, the closer it comes to the rotor speed, the lower the current draw will be. When the output current drops below the level as set in b3-02 (100% = iQpump drive Rated Current) the output frequency stops decreasing and normal operation resumes.

◆ b3-03 Speed Search Deceleration Time

Setting Range: 0.1 ~ 10.0 s

Factory Default: 2.0 s

Parameter b3-03 sets the deceleration ramp used by the current detection method of Speed Search when searching for the motor’s rotor speed. Even if Speed Search 2 is selected, for Speed Search at start, the time entered into b3-03 will be the time to decelerate from maximum frequency (E1-04) to minimum frequency (E1-09).

YASK AWA TM.iQp.07 iQpump Controller Programming Manual 29

◆ b3-05 Speed Search Delay Time

Setting Range: 0.0 ~ 20.0 s

Factory Default: 0.2 s

In cases where an output contactor is used between the iQpump drive and the motor, extra waiting time is provided after power returns and before Speed Search is performed. This extra time allows for the contactor to operate. When Speed Search at start is used, b3-05 will serve as the lower limit of the Minimum Baseblock Time (L2-03).

◆ b3-14 Bi-Directional Speed Search Selection

Setting Description

0Disabled 1 Enabled (factory default)

The b3-14 parameter can be used to turn off the bi-directional capabilities of the Speed Estimation form of Speed Search. By turning off the bi-directional capability, the speed search will only try to match the speed in the last known direction.

PI Feedback

The capability to accept an analog signal as feedback for a PI (Proportional + Integral) control function is built into the drive.

Figure 1.26

The analog feedback to the iQpump drive for the PI control is via the A2 terminal. The iQpump drive must be programmed (H3-09 = “B: PI Feedback”) to use terminal A2 as feedback for the PI functionality of the drive.

The PI Setpoint can be configured to come from one of many different inputs or parameters. Table 6 on page 32 describes the options for originating the PI Setpoint.

The PI Setpoint will be read from:

MEMOBUS/Modbus Register 06H 0 ON N/A

In some situations there are two feedback inputs. The drive can be programmed to maintain a set differential between two analog signals. If input A2 is configured as a “PI Differential Mode” (H3-09 = “16: PI Differential”), then the iQpump drive will maintain a set difference between the measurements read on inputs A1 and A2. This differential setpoint is programmed by parameter (b5-07).

When Dual Zone PI Operation is enabled:

• When the drive is in auto mode, the digital operator display will change as noted in Table 6 on page 32.

• Terminal A1 becomes a PI feedback, assigned to Zone 1.

• Standard PI feedback is assigned to Zone 2 (requires H3-09 = B).

• If feedback on Terminal A1 within the P4-17 value of the feedback on Terminal A2, the drive will use the d1-04 parameter as the setpoint. It will use either Terminal A1 or Terminal A2 as feedback depending on which one is higher. The feedback signal(s) need to be different for more than 5 seconds before any switching between the two will occur.

• If the feedback on Terminal A1 is more than the feedback on Terminal A2 plus the P4-17 value for more than 5 seconds, the drive will then operate off of the Zone 1 setpoint (d1-02) and the Zone 1 feedback (Terminal A1).

• If the feedback on Terminal A2 is more than the feedback on Terminal A1 plus the P4-17 value for more than 5 seconds, the drive will then operate off of the Zone 2 setpoint (d1-03) and the Zone 2 feedback (Terminal A2).

From the main “Auto Mode” display see Table 6 on page 32, if the <Data / Enter> key is pressed, the currently active setpoint will be editable.

Note: To convert Terminal A1 to a 4 - 20 mA signal, connect a 250 Ohm precision resistor (1/4 Watt or greater) between A1

◆ b5-02 Proportional Gain Setting

Setting Range: 0.00 ~ 25.00

Factory Default: 2.00

The proportional gain will apply a straight multiplier to the calculated difference (error) between the PI Setpoint and the measured transmitter feedback at terminal A2. A large value will tend to reduce the error but may cause instability (oscillations) if too high. A small value may allow to much offset between the setpoint and feedback (See Figure 29. on following page).

TIME

Setting Range: 0.0 ~ 360.0 s

The Integral factor of PI functionality is a time-based gain that can be used to eliminate the error (difference between the setpoint and feedback at steady state). The smaller the Integral Time set into b5-03, the more aggressive the Integral factor will be. To turn off the Integral Time, set b5-03 = 0.00.

Figure 29. PI Feedback Response Characteristics

◆ b5-04 Integral Limit Setting

Setting Range: 0.0 ~ 100.0%

Factory Default: 100.0%

On some applications, especially those with rapidly varying loads, the output of the PI function may have large oscillations. To suppress these oscillations, a limit can be applied to the integral factor by programming b5-04.

◆ b5-06 PI Output Limit

Setting Range: 0.0 ~ 100.0%

Factory Default: 100.0%

Places a cap on the output of the PI function. Limiting the PI function may help to prevent large overshoots in the drive’s response to error (the difference between the setpoint and the feedback).

◆ b5-07 PI Offset Adjustment

Setting Range: -100.0% ~ +100.0%

Factory Default: 0.0%

The PI Offset Adjustment parameter has two different uses. Parameter b5-07 serves different functions depending on whether it is used on a standard PI loop or a Differential PI loop.

Parameter b5-07 causes an offset to be applied to the output of the PI function in a non-Differential PI loop. Every time the PI output is updated, the offset (b5-07) is summed with the PI output. This can be used to artificially kick-start a slow starting PI loop.

If the iQpump drive is configured for Differential PI Regulation (H3-09 = “16: PI differential”), then this parameter is the target setpoint for the differential to be maintained between the signal measured on analog input A1 and the signal measured on analog input A2.

36 YASK AWA TM.iQp.07 iQpump Controller Programming Manual

◆ b5-08 PI Primary Delay Time Constant

Setting Range: 0.00 ~ 10.00 s

Factory Default: 0.00 s

Acts as a time based filter that lowers the responsiveness of the PI function, but also makes the function more stable when the setpoint varies rapidly or when the feedback is noisy.

◆ b5-09 PI Output Level Selection

Setting Description

0 Normal Output (direct acting) (factory default) 1 Reverse Output (reverse acting)

Normally, the output of the PI function causes an increase in motor speed whenever the measured feedback is below the setpoint. This is referred to as direct acting response. However, if b5-09 = “1: Reverse Output,” the output of the PI function causes the motor to slow down when the feedback is below the setpoint. This is referred to as reverse acting response.

◆ b5-10 PI Output Gain Setting

Setting Range: 0.0 ~ 25.0

Factory Default: 1.0

Applies a multiplier to the output of the PI function. Using the gain can be helpful when the PI function is used to trim the Speed Command. Increasing b5-10 causes the PI function to have a greater regulating affect on the speed command.

◆ b5-12 PI Feedback Reference Missing Detection Selection

Setting Description

0Disabled 1Alarm 2Fault (factory default)

Loss of feedback can cause problems to a PI application. The iQpump drive can be programmed to turn on a digital output whenever a loss of feedback occurs. Feedback Loss Detection (FBL) is turned on by b5-12. When b5-12 = “1: Alarm,” the iQpump drive acknowledges the loss of feedback without stopping or turning on the fault output (MA-MB). If b5-12 = “2: Fault,” the iQpump drive coasts to a stop and turns on the fault output if the feedback is determined to be lost.

The Feedback Loss Detection can be disabled during the following conditions:

• Pre-charge Level (P4-01) is set to 0.

• Thrust Bearing acceleration or deceleration.

Note: A Feedback Loss Detection (FBL) will occur when the Thrust Bearing function is enabled and a run command given, P1

Feedback Loss Detection Time (b5-14) is set to 0, and P1 Feedback is below Feedback Loss Detection Level (b5-13).

Function Description

This parameter also allows feedback loss detection to also function as a wire break detection when the signal type is 4 ~ 20mA. The Wirebreak Feedback Loss Detection will still be active when b5-13 = 0%.

Wire break will be detected on Terminal A2 when:

• PI Feedback Loss Detection is enabled (b5-12 = 1 or 2)

• PI is enabled (b5-01 > 0)

• Terminal A2 9s set for PI Feedback (H3-09 = B)

• Terminal A2 is set for 4 ~ 20 mA (H3-08 = 2)

• PI is NOT disabled via Multi-Function Digital Input

• Signal on Terminal A2 goes below 3 mA or above 21 mA for more than 1 s.

Note: Wire break detection on Terminal A2 is unaffected by the gain / bias parameters H3-10 and H3-11.

Wire break will be detected on Terminal A1 when:

<0034>

• PI Feedback Loss Detection is enabled (b5-12 = 1 or 2)

YASK AWA TM.iQp.07 iQpump Controller Programming Manual 37

• PI is enabled (b5-01 > 0)

• Dual Zone PI is enabled (b5-01 = 2, P1-01 = 0, b5-09 = 0, and H3-09 = B)

• PI is NOT disabled via Multi-Function Digital Input

• Signal on Terminal A1 goes below -6.25% or above 106.25% for more than 1 s.

Note: Wire break detection on Terminal A1 occurs after the gain / bias parameters (h3-02 and H3-03) are applied.

Feedback Loss (wire-break):

The drive will then react depending on how parameter b5-12 is programmed. However, if b5-12 is set to “fault” (b5-12 = 2), the drive will only fault when running in “Auto” mode. A warning will only be displayed if the drive is not running, or is running in “Hand” mode.

Feedback Loss (standard):

Note: To convert terminal A1 to a 4 ~ 20 mA signal, connect a 250 Ohm precision resistor (1/4 W or greater) between A1 and

AC. Then program H3-02 = 231.2% and H3-03 = 25.0%.

◆ b5-17 PI Accel / Decel Time

Setting Range: 0.0 ~ 25.5 s

Factory Default: 0.0 s

This is a soft start function that is applied to the PI Setpoint analog input. Instead of having nearly instantaneous changes in signal levels, there is a programmed ramp applied to level changes. When changing setpoints the error can be limited by gradually ramping the setpoint through the use of parameter b5-17.

◆ b5-32 Integrator Ramp Limit <0034>

The Integrator Ramp Limit provides a way to tune the PI loop so that it is less reactive to sudden spikes and dips in the feedback signal. Sometimes in a pressure regulated system with a very long piping system, pressure waves can develop which without this feature, can cause instability in the PI controller.

This feature only applies to the drive’s standard PI Loop. It will not be applied to the PI Loop associated with water level control (Well Draw Down Control).

Function Description

When the Integrator Ramp Limit is enabled, the PI Integrator is limited to +/- the b5-32 value of the soft starter output (output frequency without slip compensation). A b5-32 setting of zero disables this feature and the integrator is allowed to operate normally.

b8 Energy Savings

The energy savings function improves overall system operating efficiency by operating the motor at its highest efficiency. This is accomplished by continuously monitoring the motor load and adjusting the motor terminal voltage so that the motor always operates near its rated slip frequency. A motor is most efficient when operating near rated slip conditions.

◆ b8-01 Energy Savings Selection

Setting Description

0 Disabled (factory default) 1 Enabled

When the Energy Savings function is enabled (b8-01 = “1: Enabled”), the iQpump drive reduces the output voltage to the motor below the voltage value specified by the programmed V/f pattern whenever the motor load is light. Since torque is reduced during this voltage reduction, the voltage has to return to normal levels when the load returns. The energy savings is realized through improved motor efficiency. The reduced output voltage causes increased rotor slipping even with a light load. A motor is most efficient when operating fully loaded (i.e. operating at rated slip).

◆ b8-04 Energy Saving Coefficient Value

Setting Range: 0.0 ~ 655.0

Factory Default: Model Dependent

Parameter b8-04 is used in maximizing motor efficiency. The factory setting will be iQpump drive capacity dependant but can be adjusted in small amounts while viewing the kW monitor (U1-08) and running the iQpump drive to minimize the output kW. A larger value typically results in less voltage to the motor and less energy consumption. Too large a value will cause the motor to stall.

◆ b8-05 Power Detection Filter Time

Setting Range: 0 ~ 2000 ms

Factory Default: 20 ms

The Energy Saving function will search out the lowest output voltage in order to achieve minimum output power usage. Parameter b8-05 determines how often the output power (kW) is measured and the output voltage is adjusted.

◆ b8-06 Search Operation Voltage Limit

Setting Range: 0 ~ 100%

Factory Default: 0%

Once Energy Savings is enabled and the optimal energy saving coefficient value has been set, the programmer can have the iQpump drive further search out the proper voltage to achieve the lowest output power by making minute changes to the output voltage and measuring the output power every b8-05 ms. Parameter b8-06 sets limits to the range over which the voltage will be adjusted in order to minimize the power output. Settings too large a value may allow the motor to stall if the load is applied abruptly.

If b8-06 = 0, then the optimum voltage search operation is disabled (but not Energy Savings itself).

C1-01 Acceleration Time 1 C1-02 Deceleration Time 1 C1-03 Acceleration Time 2 C1-04 Deceleration Time 2 C1-05 Acceleration Time 3 C1-06 Deceleration Time 3

Setting Range: 0.0 ~ 6000.0 s

Factory Defaults: C1-01 20.0 s

C1-02, C1-03 and C1-04 10.0 s C1-05 and C1-06 50.0 s

C1-01 (Acceleration Time 1) sets the time to accelerate from zero to maximum speed (E1-04). C1-02 (Deceleration Time 1) sets the time to decelerate from maximum speed to zero. C1-01 and C1-02 are the factory default active accel / decel “pair”. Another accel / decel pair (C1-03 and C1-04) exists that can be activated by a multi-function digital input (H1-0x = 7), or specified by a switch over frequency as programmed in parameter C1-11.

C1-05 (Acceleration Time 3) and C1-06 (Deceleration Time 3) are used during the multiple pumping operation. Refer to P3-12 for more details.

Acceleration Time: This is the time it takes to accelerate from 0 Hz to Maximum Output Frequency defined by parameter E1-04.

Deceleration Time: This is the time it takes to decelerate from Maximum Output Frequency defined by parameter E1-04 to 0 Hz.

Example: C1-01 Acceleration Time 1 programmed for 30 seconds, E1-04 Maximum Output Frequency set to 60 Hz. It will take the iQpump Controller 20 seconds to accelerate from 0 to 40 Hz (40 Hz ÷ 60 Hz x 30 s = 20 s).

Example: C1-02 Deceleration Time 1 programmed for 50 seconds, E1-04 Maximum Output Frequency set to 60 Hz. It will take the iQpump Controller 10 seconds to decelerate from 60 to 30 Hz (30 Hz ÷ 60 Hz x 50 s = 25 s).

• Thrust Bearing Operation uses a separate acceleration time defined by parameter P4-04. Once Thrust frequency is reached, the iQpump drive returns to its normal acceleration time set by C1-01.

• Pre-charge mode uses C1-01 as its acceleration time.

• Hand Mode Operation uses C1-01 and C1-02 for acceleration and deceleration time.

• Auto Mode can use acceleration time C1-05 and deceleration time C1-06, depending on parameter P3-12 setting (see section. P3-12

Delta Setpoint Feedback Acc / Dec Changeover on page 183.)

◆ C1-09 Fast Stop Time

Setting Range: 0.0 ~ 6000.0 s

Factory Default: 10.0 s

A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a special deceleration that can be operated by closing a digital input configured as H1-0x = 15 or H1-0x = 17. A digital input configured as H1-0x = 15 will look for a switch closure before initiating the Fast Stop operation. A digital input configured as H1-0x = 17 will look for the switch opening before initiating the Fast Stop operation.

Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the iQpump drive cannot be re-operated until the deceleration is complete, the Fast Stop input is cleared, and the Run command is cycled.

The C1-05 (Acceleration Time 3) and C1-06 (Deceleration Time 3) are used during the multiplex pumping operation. Refer to P3-12 for more details.

Time

C1-11

C1-03 Rate C1-01 Rate

Setting Range: 0.0 ~ 200.0 Hz

Factory Default: 0.0 Hz

The iQpump drive can be programmed to automatically switch between the two sets of Accel / Decel parameters on the fly. No digital input is required. If parameter C1-11 is set to a frequency other than zero, the iQpump drive will use Acceleration 1 and Deceleration 1 whenever the output frequency is equal to or above the value of C1-11 and use Acceleration 2 and Deceleration 2 whenever the output frequency is below the value of C1-11.

A multi-function input programmed as “Multi-Acc / Dec 1” will have priority over C1-11. For example, if the output frequency is greater than the value of C1-11 but a digital input configured as “Multi-Acc / Dec 1” is closed then Acceleration 2 and Deceleration2 are active.

Parameters C2-01 and C2-02 will affect the acceleration rate of the output frequency in order to reduce shock to the load. The S-curve addition to the acceleration profile can ramp the acceleration rate from a 0 to the rate specified by the active Acceleration Time (C1-01 or C1-03) and back to 0.

Figure 1.32

The S-Curve transition into and out of the active acceleration rate can be programmed independently. C2-01 will ramp up the acceleration from no acceleration up to the rate of C1-01 or C1-03. C2-02 will ramp the acceleration rate from the rate of C1-01 or C1-03 back down to no acceleration (constant speed). The use of S-Curve characteristics will lengthen the overall acceleration time as follows:

◆ C4-01 Torque Compensation Gain

Setting Range: 0.00 ~ 2.50

Factory Default: 1.00

Refer to parameter C4-01 in Appendix A for description details.

◆ C4-02 Torque Compensation Primary Delay Time

Setting Range: 0 ~ 10000 ms

Factory Default: 200 ms

The Torque Compensation function compensates for insufficient torque production at start-up and during low speed operation. The iQpump drive will detect increases in the motor load by monitoring the output current and compensate by increasing the output voltage. The increased output voltage leads to an increase in usable torque.

Parameter C4-01 sets the aggressiveness of the compensation for IR (resistive) and IL (inductive) losses in the motor windings, which are more pronounced at lower speeds. Normally C4-01 does not need to be changed but may require adjustment in the following cases:

• If the iQpump drive to motor cable is long, increase C4-01

• If the motor capacity is smaller than the iQpump drive capacity, increase C4-01

• If the low speed motor performance is unstable, decrease C4-01.

• If the output current level exceeds the drive’s rated current while operating at low speeds, increase C4-01

Parameter C4-02 determines how quickly the Torque Compensation function will react to situations of insufficient torque. Again, C4-02 will not normally require adjustment except for the following situations:

• If the motor vibrates, increase C4-02

• If the motor response is sluggish (and possibly stalls), decrease C4-02

Important: Performing Auto-tuning can enhance low speed performance.

Setting Description

FProgram

*The factory default setting is model dependent

Parameter C6-02 sets the switching frequency of the drive’s output transistors. It can be changed in order to reduce audible noise and also reduce leakage current. Cases that may require adjustment to the C6-02 are:

• If the wiring length between the iQpump drive and the motor is long, decrease the carrier frequency

Wiring Length 328 ft or less Over 328 ft

C6-02 (carrier frequency) setting 1 ~ 4 (10 kHz max.) 1 ~ 2 (5 kHz max.)

• If speed and torque are inconsistent at low speeds, decrease the carrier frequency

• If leakage current from the iQpump drive is large, decrease the carrier frequency

• If the audible motor noise is too great, increase the carrier frequency (may require iQpump drive current derating)

When parameter C6-02 is set to “0: Low Noise” the iQpump drive uses a carrier frequency of 2 kHz and reduces the motor audible noise by approximately 5 db. over the conventional 2 kHz setting (C6-02 = 1). The iQpump drive modulates the nominal PWM pattern to achieve the lower noise. This setting is normally used with high starting torque loads that are frequently started and stopped or, applications where leakage current needs to be minimized and motor audible noise is important.

First, d1-01 through d1-04 and d1-17 must be programmed with the desired setpoint references and the desired jog reference, respectively. Next, up to three of the drive’s digital inputs (Terminals S3 through S7) need to be programmed (via parameters H1-01 to H1-05) and wired (to normally open contacts) as Multi-step SP1, Multistep SP2, and Jog Frequency.

• If H3-09 = “2: Aux Reference” then the analog input A2 will be used instead of Setpoint Reference 2 for the second preset Setpoint. If H3-09 = 2 then Setpoint Reference 2 will be used. This is only available when the iQpump drive is operating in the speed mode.

Important: The programming of d1-01 through d1-04 and d1-17 will be affected by the setting of P1-02 and o1-03, respectively. The programming of these parameters will be in the units specified by Display Scaling parameter (P1-02 and o1-03).

◆ d2-02 Frequency Reference Lower Limit

Setting Range: 0.0 ~ 110.0%

Factory Default: 0.0%

The use of parameters d2-01 and d2-02 places limitations on the speed command that the iQpump drive will accept. The parameters are set in units of percentage of the maximum frequency (E1-04) and provide limits on any remote speed command input. By entering upper or lower frequency limits, the iQpump drive programmer can prevent operation of the iQpump drive above or below levels that may cause resonance, equipment damage or discomfort (see also parameter d3-0X). For example, limits may be needed to prevent low speed operation of: Cooling tower fans with gear boxes, pumps with pressure dependent seals, or AHUs with minimum delivery requirements.

Unlike Frequency Reference Lower Limit (d2-02) which will affect the speed command no matter where it is sourced from (i.e. analog input, preset speed, jog speed, etc.), the Master Speed Reference Lower Limit (d2-03) sets a low speed threshold that will only affect the analog input that is the active master speed frequency (as determined by parameter H3-13 and H3-09). This parameter allows a minimum speed to be programmed for the master reference while allowing a lower speed to be set as a jog reference. If the speed commanded by the active master speed frequency is below the setting of d2-03, then the iQpump drive will operate at the speed specified by d2-03.

◆ d3-04 Jump Frequency Width

Setting Range: 0.0 ~ 20.0 Hz

Factory Default: 1.0 Hz

In order to avoid continuous operation at a speed that causes resonance in driven machinery, the iQpump drive can be programmed with jump frequencies that will not allow continued operation within specific frequency ranges. If a speed is commanded that falls within a dead band, or Jump Frequency, the iQpump drive will clamp the frequency reference just below the dead band and only accept higher speed commands when the commanded speed rises above the upper end of the dead band, for increasing references. Similarly, the iQpump drive will clamp the frequency reference just above the dead band and only accept lower speed commands when the command speed falls below the lower end of the dead band, for decreasing references.

Set the Input Voltage parameter (E1-01) to the nominal voltage of the connected AC power supply. This parameter adjusts the levels of some protective features of the iQpump drive (i.e. Overvoltage, Stall Prevention, etc.). E1-01 also serves as the Maximum / Base Voltage used by the Preset V / Hz curves (E1-03 = 0 ~ D).

, with parameter values per setting 1)

The iQpump drive operates utilizing a set V/f pattern to determine the appropriate output voltage level for each commanded speed. There are 14 different preset V/f patterns to select from with varying voltage profiles, saturation levels (frequency at which maximum voltage is reached), and maximum frequencies.

There are also settings for Custom V/f patterns that will allow the programmer to manually set (“Customize”) the V/f pattern using parameters E1-04 through E1-13.

Using parameter E1-03, the programmer can select one of the preset V/f patterns or chose between a custom V/f pattern with an upper voltage limit (E1-03 = “F: Custom V/f”) and a custom V/f pattern without a voltage limit (E1-03 = “FF: Custom w/o limit”).

◆ E2-01 Motor Rated Current

Setting Range: 10% ~ 200%

Factory Default: Model Dependent

The Motor Rated Current parameter (E2-01) is necessary information for the iQpump drive motor protection function. The motor overload protection parameter L1-01 is enabled by default. In addition, motor rated current is used by the torque compensation function to insure optimum torque production. Set E2-01 to the full load amps (FLA) value stamped on the motor’s nameplate. During Autotuning, it is required for the operator to enter the motor rated current in parameter T1-04 on the Auto-Tuning menu. If the Auto-tuning operation completes successfully, the value entered into T1-04 will be also written into E2-01.

For applications employing an iQpump drive that is oversized for the motor, E2-01 may be set as low as 10% of the iQpump drive output current rating. The AMP value in E2-01, however, must always be greater than the “No Load Current” value in parameter E2-03 or an OPE02 error will be displayed.

◆ E2-03 No Load Current

Setting Range: Model Dependent (see Appendix B)

Factory Default: Model Dependent

Set E2-03 to the motor no-load current at rated voltage and rated frequency. Consult the motor manufacturer for the proper value if the no load current is not stated on the motor nameplate.

Sets the line-to-line resistance of the motor’s stator winding. Usually determined by performing Auto-tuning. If Auto-tuning cannot be completed without error, then manually set E2-05 to the value as determined by the motor manufacturer. Remember this value must be entered as line-line and not line neutral.

If a serial communication option board is attached to the iQpump drive at the 2CN connector, the iQpump drive will automatically monitor the card for any type of communication errors. F6-01 is applicable no matter whether a run command or speed command is coming via the option board, digital operator, or terminal input. The setting of F6-01 determines whether the communication error is seen as a fault or an alarm. If F6-01 = “3: Alarm Only,” then the fault output is not energized upon a communication error. All other settings of F6-01 cause the fault output to energize. The setting of F6-01 does not apply to any of the embedded communication protocols used at the RS-485 / 422 terminals on the removable terminal board. (See parameters H5-0X.)

If an external fault is received from a communication option card, the settings of F6-02 and F6-03 will determine the iQpump drive operation in reaction to the fault signal. Parameter F6-02 will determine if the external fault is always recognized (F6-02 = “0: Always Detected”) or only recognized when the Run command is active (F6-02 = “1: Detected only during operation”).

Once the fault is recognized, parameter F6-03 will determine the operation of the drive. If parameter F6-03 is set to anything other then “3,” the iQpump drive will fault and a stopping sequence is begun. If F6-03 = “3: Alarm Only,” then the external fault is treated like an alarm. Operation will continue and an EF0 fault will flash on the digital operator.

Location

When one of the digital inputs is programmed for 3-Wire control, that input becomes a Forward / Reverse directional input. Whenever the input is open, the iQpump drive will be set for forward rotation of the motor shaft. If the input it closed, then the motor shaft will rotate in the reverse direction whenever a there is a Run input. The S1 and S2 digital inputs will function as a Run and Stop input respectively.

Function: Option / Inv Selection 1 (Setting: 2)

■

The Option / Inv Selection function allows the user to select the source for the Run and speed commands between either the drive’s terminals or an optional communication card. When a digital input is programmed for the Option / Inv Selection function (H1-0x = 2) that input will function as follows:

Table 22 Digital Input Functions

Option / Inv Selection Input Status Run and Speed Command Source

CLOSED From the control circuit and analog input terminals

OPEN From the Communications Option Card

To switch the command source between the option card and the terminals be sure to program the following parameters:

• Set b1-01 (Auto Setpoint Reference Selection) to 1 (Terminals).

•Set (Run Command Selection) to 1 (Terminals).

• Set H1-0x (Input Terminal Function Selection) to 2.

Important: Switching between the different Reference and Run sources can only be done while the iQpump drive is stopped.

■ Function: Multi-step SP1 (Setting: 3)

■ Function: Multi-step SP2 (Setting: 4)

The iQpump drive can be programmed to step through four preset setpoints and a jog reference. It is also possible to mix in the analog inputs as setpoint references that can be chosen in place of the first and second preset setpoint references. The selection of which preset setpoint will be the active setpoint is determined by the status of the digital inputs set for Multi-step SP1 (H1-0x = 3) and Multi-step SP2 (H1-0x = 4). Changing the active setpoint via the Multi-step Setpoint References can be done while the iQpump drive is running.

The following table details which reference is active based on the status of the Multi-step SP1 and Multi-step SP2 inputs:

(determined by H3-09)

The determination of whether the Preset Reference 1 will be the Setpoint Reference 1 (d1-01 or the analog input A1) is determined by the status of b1-01. If b1-01 = “1: Terminals,” the value of the input to A1 will determine the commanded Setpoint when Preset Reference 1 is selected. If b1-01≠1, the setting of d1-01 will determine the commanded Setpoint when Preset Reference 1 is selected.

The determination of Preset Reference 2 is made much the same way as Preset Reference 1 except that the setting of parameter H3-09 decides whether the analog input A2 or d1-02 is Preset Setpoint 2. If H3-09 = “2: Aux Reference,” the value of the input to A2 will determine the commanded Aux Reference when Preset Reference 2 is selected. If H3-09 = 2, the setting of d1-02 will determine the commanded setpoint when Preset Reference 2 is selected.

■ Function: Ext Baseblk N.O. (Setting: 8)

■ Function: Ext Baseblk N.C. (Setting: 9)

When the iQpump drive is commanded into baseblock, gating of the output transistor stops and output voltage/frequency drops to zero (motor coasts). The iQpump drive can be forced into a baseblock state by either closing a digital input configured for Ext Baseblk N.O. (H1-0x = 8) or opening a digital input configured for Ext Baseblk N.C. (H1-0x = 9).

When the baseblock state is removed the speed search function is used to catch the coasting motor and ramp it back to the commanded speed.

The method of speed search, Current Detection or Speed Estimation, that is utilized when the baseblock input is removed depends on the setting of parameter b3-01:

If b3-01 = “0: SpdsrchF Disable” or “1: SpdsrchF Enable”; Speed Estimation is used

If b3-01 = “2: SpdsrchI Disable” or “3: SpdsrchF Enable”; Current Detection is used

Function: Acc / Dec Ramp Hold (Setting: A)

The Acc / Dec Ramp Hold function will clamp (“hold”) the speed of the output frequency whenever a digital input that has been programmed for it (H1-0x = A) is closed. All acceleration or deceleration will stop and the iQpump drive will hold the current speed. Once the input is opened, acceleration or deceleration continues.

The Acc / Dec Ramp Hold function is affected by parameter d4-01. If d4-01 = “1: Enabled” and the Acc /Dec Ramp Hold functions are both being used, whenever the RampHold input is closed the output frequency is memorized. When interrupted power is returned and a Run command is input, the Speed Command will be the last output frequency memorized by the Acc / Dec Ramp Hold function, if the Acc / Dec Ramp Hold input is still closed.

■ Function: Term A2 Enable (Setting: C)

Any digital input configured as Term A2 Enable (H1-0x = C) when open will cause the input to analog input A2 to be ignored.

If analog input A2 is configured as the Main Reference (H3-13 = “1: Main Fref TA1”), then the Term A2 Enable input will have no effect.

■ Function: Term Not Used (Setting: F)

Any digital input programmed as Term Not Used (H1-0x = F) will have no function assigned to it and it’s OPEN / CLOSED state will not matter to the drive’s operation.

■ Function: MOP Increase (Setting: 10)

■ Function: MOP Decrease (Setting: 11)

Using two digital inputs, the iQpump drive can operate with the same type of functionality as a motor operated potentiometer (MOP). One digital input can be programmed as an MOP Increase input (H1-0x = 10) and another digital input can be programmed as an MOP Decrease input (H1-0x = 11). This MOP functionality is also commonly referred to as Floating Point Control, Incremental Control or UP and DOWN Control since closing the MOP Increase input will cause the speed command to increase and closing the MOP Decrease input will cause the speed command to decrease.

If both the MOP Increase and the MOP Decrease are closed or open simultaneously, the speed will command will not change. The speed command will change at the active acceleration or deceleration rate.

MOP Increase cannot be programmed without also programming the MOP Decrease (or vice versa) else an OPE03 fault will occur. Setting the MOP Increase / Decrease function while the Acc / Dec RampHold function is programmed into other digital inputs will also cause an OPE03 fault.

Once the MOP function is programmed the preset speeds are disabled and the analog speed command input becomes a potential frequency reference lower limit. The lower limit of the MOP function is the greater of the analog speed command and the programmed frequency reference lower limit (d2-03). Once a Run command is issued the iQpump drive will accelerate immediately to the lower limit. The upper limit will be the Frequency Reference Upper Limit (d2-01), if used, otherwise the Maximum Frequency (E1-04).

The status of the d4-01 parameter (MOP Reference Memory) will affect the performance of the iQpump drive after power is cycled to the iQpump drive and a fresh Run command is issued. If d4-01 = “0: Disabled,” the Run command will cause the iQpump drive to ramp to the frequency reference lower limit. However, if d4-01 = “1: Enabled,” the Run command will cause the iQpump drive to ramp to the last speed commanded by the MOP function before the Run command was removed and the power cycled. Even if d4-01 = “1: Enabled,” the

without having a Run command active.

Important: Be sure to set b1-01 = “1: Terminals,” (Auto Setpoint = Terminals) if the MOP function is to be used. If b1-01 = “0: Operator,” then the MOP is disabled even if it is programmed. The Jog inputs have priority over the MOP function.

■ Function: Fault Reset (Setting: 14)

Whenever the iQpump drive detects a fault condition, the fault output contact will close and the drive’s output will shut OFF causing the motor to coast (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). Once the Run command is removed, the fault can be reset by either the RESET key on the digital operator or by closing a digital input configured as a Fault Reset (H1-0x = 14).

■ Function: Fast Stop N.O. (Setting: 15)

■ Function: Fast Stop N.C. (Setting: 17)

The Fast Stop function operates much like an emergency stop input to the drive. While in the Run mode, if a Fast Stop is input to the iQpump drive (CLOSED for H1-0x = 15 or OPEN for H1-0x = 17), the iQpump drive will decelerate to a stop with the deceleration time determined by C1-09 (Fast Stop Time). The Run command can remain closed during the Fast Stop operation. The iQpump drive will not run, from either the terminals or the digital operator, while the Fast Stop is being input to the drive. To restart the drive, the Fast Stop input must be removed and the Run command must be cycled.

Important: Be aware that during rapid deceleration the iQpump drive may fault on an over voltage condition. When faulted, the iQpump drive output shuts off allowing the motor to coast. The result is an uncontrolled motor state. Therefore, be sure to set an acceptable deceleration time in parameter C1-09 when using the fast stop feature.

■ Function: Timer Function (Setting: 18)

The Timer Function works independently from the drive. For Timer operation a digital input must be configured for a Timer Function start (H1-0x = 18), a digital output must be configured as a Timer Function output (H2-0x = 12), and the Timer Function ON-Delay and OFF-Delay parameters (b4-01 and b4-02, respectively) must be programmed.

Once the applicable parameter are programmed the Timer Function start digital input must be closed at least as long as the setting of b401 before the Timer Function output will close. The Timer Function input must be open for at least as long as the setting of b4-02 before the Timer Function output will reopen.

■ Function: Program Lockout (Setting: 1B)

A Program Lockout digital input will allow changing of parameter values when it is open but prevent changing of any iQpump drive parameter value except the Speed Command when it is closed. Parameter values can be viewed even when a Program Lockout is active.

■ Function: PI Disable (Setting: 19)

When the PI Function has been enabled by b5-01 (PI Mode Selection), it can be indefinitely disabled by closing a digital input configured as a PI Disable input (H1-0x = 19). When disabled, the iQpump drive operates as a standard drive that does not have PI enabled.

External Fault functionality can be programmed into the digital inputs of the drive. The External Fault inputs can be used to signal to the iQpump drive that other equipment related to the operation of the iQpump drive has experienced problems. If the External Fault is input to the iQpump drive the digital operator will display as shown in the illustration below:

The x in EFx and Sx represent the terminal number of the digital input that the fault was received on.

To program an External Fault the value input into the H1-0x parameter will determined by:

• Contact type wired to the terminal (Normally Open or Normally Closed)

• Detection profile (Always Detected or Only Detected while Running)

• Drive operation after fault (Stopping Method or Continue Operation)

■ Function: PI Integral Reset (Setting: 30)

By configuring one of the digital inputs as an Integral Reset Input, (H1-0x = 30), the value of the integral component of PI control can be reset to zero whenever the configured input is CLOSED. The integral component of PI control will be held at zero as long as the configured digital input is held CLOSED.

Resetting the Integral component of PI control can be useful in cases where an excessively large Integral value prevents the PI control from responding quickly to changes in the system being regulated by the iQpump drive (e.g. duct pressure, water temperature).

Function: PI Integral Hold (Setting: 31)

By configuring a digital input as an Integral Hold input (H1-0x = 31), the value of the Integral component of the PI control can be forced to clamp at the value it was at when the input is CLOSED. The Integral component of the PI control returns to accumulating error when the digital input is OPEN again.

Holding the Integral Value can be useful during periods when the error can build up naturally, such as during long accelerations. Not allowing Integral windup produces a more stable PI control.

Function: PI SFS Cancel (Setting: 34)

SFS means softstart, also referred to as accel / decel in this description.

By configuring a digital input as a PI SFS (softstart) Cancel input (H1-0x = 34), the operator will be able to use a contact closure to remove the acceleration and deceleration times that are applied to changes in the PI Setpoint by the b5-17 parameter. If the digital input configured as PI SFS Cancel is closed, the PI Setpoint Accel / Decel (Parameter b5-17) will be ignored. Immediate updating of any change to the setpoint will apply.

■ Function: Input Level Sel (Setting: 35)

When using the PI Function built into the drive, the chosen setpoint is compared with the measured feedback. The difference is called the Error. The proportional and integral function are applied to this error. For some applications it may be appropriate to invert the input to the PI block. This can be accomplished by setting one of the digital inputs up as an Input Level Sel (H1-0x = 35). When an Input Level Sel digital input is closed the Error will be inverted before it is passed to the PI block.

■ Function: Option / Inv Sel 2 (Setting: 36)

The Option / Inv Selection function allows the user to switch the source of the Run and speed command between the drive’s terminals and optional communication card. When a digital input is programmed for the Option / Inv Selection 2 function (H1-0x = 36) that input will function as follows:

Table 25 Programming Choices

Option / Inv Function Input Status Run and Speed Command Source

CLOSED From the Communications Option Card

OPEN From the control circuit and analog input terminals

To switch the command source between the option card and the terminals be sure to program the following parameters:

• Set b1-01 (Frequency Reference Selection) to 1 (Terminals).

• Set b1-02 (Run Command Selection) to 1 (Terminals).

• Set H1-0x (Input Terminal Function Selection) to 36.

Important: Switching the Reference and RUN sources can only be done while the iQpump drive is stopped.

■ Function: Motor Pre-heat (Setting: 60)

In order to prevent condensation on the motor windings, a DC current can be circulated through the windings. The heat produced by the current in the windings will prevent the moisture from condensation on the wire. Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat input (H1-0x = 60). The level of the DC current used by the Motor Pre-heat function is determined by parameter b2-09.

A Run input will be given priority over a Motor Pre-heat input. When the Run command is removed, if the Motor Pre-heat input is still closed, the motor pre-heating will resume.

The Speed Search function can be turned on for all starts with parameter b3-01. If, however, it is beneficial to only use Speed Search at certain starts, a digital input can be programmed to turn on Speed Search only when it is closed.

Speed Search 1 will start searching for the rotor speed from the maximum frequency (E1-04). Speed Search 2 will begin searching for the rotor speed from the existing Speed Command. Speed Search 3 will cause the motor to baseblock when the switch is open and then perform Speed Search when it closes.

In all cases the form of Speed Search, Speed Estimation or Current Detection, is determined by the setting of b3-01. If b3-01 = “0: SpdsrchF Disable,” then the Speed Estimation form of Speed Search is used. If b3-01 = “2: SpdsrchI Disable,” then the Current Detection form of Speed Search is used.

■ Function: Comm Test Mode (Setting: 67)

The iQpump drive has a built-in function for self-diagnosing the serial communications operation. The test involves wiring the send and receive terminals of the RS-485 / 422 port together. The iQpump drive transmits data and then confirms the communications are received normally.

In order to perform the serial communications self-diagnosis, terminal S7 must be programmed as the Comm Test Mode digital input (H1-05 = “67: Com Test Mode”) and then power removed from the iQpump drive and the following steps performed:

1. Wire the S7 and SC terminals of the control circuit terminals together

2. Wire the R+ and S+ terminals of the RS-485 / 422 port together

3. Wire the R- and S- terminals of the RS-485 / 422 port together

4. Turn On the terminating resistance (Move Switch 1 of Dip Switch 1 to the ON position).

If a Run command is closed prior to the iQpump drive Enable input being closed the iQpump drive will not run until the Run command is cycled.

If the iQpump drive Enable input is opened while the iQpump drive is running, the iQpump drive will stop, using the method set by parameter b1-03.

■ Function: Com / Inv Sel (Setting: 6B)

■ Function: Com / Inv Sel 2 (Setting: 6C)

The Com / Inv Selection function allows the user to switch the origin of the Run and speed command between the drive’s terminals and the RS-485 / 422 port (and the embedded communication protocols) on the removable terminal board. When a digital input is programmed for the Com / Inv Selection function (H1-0x = 6B) that input will function as follows:

• Set b1-01 (Auto Setpoint Reference Selection) to 1 (Terminals).

• Set b1-02 (Run Command Selection) to 1 (Terminals).

• Set H1-0x (Input Terminal Function Selection) to 6B or 6C.

The Com / Inv Sel 2 function will operate the same way except the logic is reversed. When a digital input is programmed for the Com / Inv Selection function (H1-0x = 6C) that input will function as follows:

Function: Hand Mode (Setting: 80)

A digital input can be configured to operate the drive in the hand mode from an external contact as a Hand Mode command (H1-0x = 80).

In conjunction with the digital input programmed to hand mode, the run command source has to be programmed to 1 (b1-02 = 1: Terminals).

The multi-function digital input terminal S6 is programmed for Hand Mode as a factory default (H1-04 = 80).

■ Function: Disable Pre-charge (Setting: 84)

A digital input can be configured to enable or disable the Pre-charge function (H1-0x = 84). A contact closure into the multi-function digital input will disable the Pre-charge function independent of the value programmed into the Pre-charge Time (P4-03). When the digital input is open, the Pre-charge function is enabled.

■ Function: Low Water Level (Setting: 85)

A digital input can be configured to indicate a Low Water Level Fault (H1-0x = 85). The Low Water Level input can be configured as a normally open or normally closed contact by programming the Water DI Config (P1-15). When P1-15 = 0 or 2, a Low Water Level Fault will occur when the contact is closed (normally open). An open contact will indicate the drive is operating under normal operating conditions.

When P1-15 = 1 or 3, a Low Water Level Fault will occur when the contact is open (normally closed). A closed contact will indicate the drive is operating under normal operating conditions.

If the Pre-charge function is activated, the Low Water Level will not cause a Low Water Level Fault. The Low Water Level will only indicate that the Pre-charge function has been completed.

If the drive is operating under normal operating condition and a Low Water Level occurs, the drive will indicate a Low Water Level Fault (LFB / LW) on the digital operator.

■ Function: Fixed Speed Auto (Setting: 86)

A digital input can be configured to enable the Fixed Speed Auto (H1-0x = 86) when operating in the Auto Mode. A contact closure into the multi-function input will enable the Fixed Speed Auto function.

The Fixed Speed Auto will cause the drive to run at the iQpump drive Multi / Maximum Level (P3-02) and disable the PI Control, Sleep Mode and Lead / Lag operation.

When the digital input is open, the Fixed Speed Auto is disabled.

Note: Pre-charge and Thrust Bearing functions have a higher priority than Fixed Speed Auto.

■ Function: Thermostat Fault (Setting:87) <0032>

H1-04 = 87 (Thermostat FltNC)

A digital input can be configured to indicate a Thermostat Fault from an external contact (H1-0x = 87). An open contact into the multifunction input will enable the Thermostat Fault. After an initiation of a Thermostat Fault to disable the Thermostat Fault requires a closed digital input contact, the drive run command to be open and reset the Thermostat Fault via the drive’s reset button or fault reset input.

Note: An OPE12 fault will occur if H1-xx = 83 and 87. H1-xx cannot be programmed to “83” and “87” at the same time.

Function: Freq Detect 1 (Setting: 4)

A “Freq Detect 1” output will be closed whenever the output frequency is equal to or below the value of the programmed Speed Agree Level (L4-01). The Speed Agree Width (L4-02) is the hysteresis to the Freq Detect 1 function. Whenever the output frequency approaches the Speed Agree Level while accelerating it will need to be equal to or exceed the Speed Agree Level (L4-01) plus the Speed Agree Width (L4-02) before the Freq Detect 1 output will energize.

As the output frequency approaches the Speed Agree Level while decelerating, the Freq Detect 1 output will de-energize exactly at the Speed Agree Level.

The Freq Detect 1 function is effective during both forward and reverse operation.

■ Function: Freq Detect 2 (Setting: 5)

A Freq Detect 2 output will be closed whenever the output frequency is equal to or above the value of the programmed Speed Agree Level (L4-01). The Speed Agree Width (L4-02) is the hysteresis to the Freq Detect 2 function. Whenever the output frequency approaches the Speed Agree Level (L4-01) while accelerating it will de-energize exactly at the Speed Agree Level.

As the output frequency approaches the Speed Agree Level while decelerating, the Freq Detect 2 output will de-energize when the output frequency is equal to or below the Speed Agree Level (L4-01) minus the Speed Agree Width (L4-02).

The Freq Detect 2 function is effective during both forward and reverse operation.

■ Function: Inverter Ready (Setting: 6)

The Inverter Ready output will be closed whenever the iQpump drive is not in a fault state and not being programmed. If b1-08 = “1: Enabled,” an iQpump drive that is in an active Run state that is also being programmed will have the Inverter Ready output closed.

■ Function: DC Bus Undervolt (Setting: 7)

The DC Bus Undervolt output will close whenever the main circuit DC Bus voltage or control circuit power supply drop below their respective trip level. The undervoltage trip level is determined by parameter L2-05. An open soft charge contactor answer back signal will also cause the DC Bus Undervolt output to close.

■ Function: BaseBlk 1 (Setting: 8)

A BaseBlk 1 programmed output will close to indicate that the iQpump drive is in baseblocked state. While in a baseblock state the drive’s output transistors are prevented from firing. A BaseBlk 1 output contact can also serve as notice that the iQpump drive has a charged DC Bus, no fault and can start at any time.

Function: Minor Fault (Setting: 10)

A Minor Fault, also referred to as an alarm, indicates that a condition exists that may be critical to the iQpump drive or application but does not require the iQpump drive to stop. A minor fault will be flashed on the digital operator but neither the Fault output (MA-MB) nor any digital output configured as a Fault output (H2-0x = E) will close. Any digital output configured as Minor Fault will close whenever a minor fault of alarm condition exists.

■ Function: Reset Cmd Active (Setting: 11)

A Reset Cmd Active digital output will close to signal that a Fault reset is being attempted from terminals or Serial Com.

■ Function: Timer Output (Setting: 12)

This Timer function, that is built into the drive, is independent of the rest of the iQpump drive operation, i.e. there is no requirement for a Run command for the timer to operate. A Timer digital output will close b4-01 seconds after a digital input configured as Timer Input (H1-0x = 18) closes and remains closed. The Timer digital output will remain closed for b4-02 seconds after the Timer digital input opens and remains open.

Refer to the descriptions of parameters b4-01 and b4-02 for a timing chart of the Timer function.

Function: Trq Det 1 N.C. (Setting: 17)

The Trq Det 1 function ties a digital output to the overtorque / undertorque sensing capabilities of the drive. If a digital output is configured as Trq Det 1 N.C., whenever the output current exceeds the level of L6-02 for at least the length of time set in L6-03, the digital output will open.

The torque detection function has a built-in hysteresis of 10% of the iQpump drive rated output current.

Figure 1.68

Figure 68. Trq Det 1 N.C. Timing Diagram

■ Function: Reverse Dir (Setting: 1A)

The Reverse Dir digital output will close whenever the iQpump drive is turning the motor in the direction that corresponds to the reverse direction (CW or CCW). The Reverse Dir digital output will remain closed during deceleration when the rotation is in the reverse direction.

■ Function: Restart Enabled (Setting: 1E)

Depending on the setting of parameter L5-01, the iQpump drive may be configured to automatically attempt to restart itself after certain faults. The Restart Enabled output will be closed once the restarts begin and will remain closed until a successful restart is accomplished or the number of Auto Restart attempts as specified by L5-01 is reached.

A timing diagram for the Auto Restart function is contained in the parameter L5-01 description.

■ Function: Overload (OL1) Alarm (Setting: 1F)

The OL1 fault function is designed to protect the motor. It estimates the motor’s winding temperature based on the output current, output frequency, and time. The OL1 time is determined by the setting of parameters E2-01, L1-01, and L1-02. An Overload digital output will close whenever 90% of the programmed OL1 time is exceeded.

■ Function: OH Prealarm (Setting: 20)

The Overheat fault function (OH) is designed to protect the iQpump drive from excessive temperature damage. Thermistors attached to the heatsink of the iQpump drive monitor the temperature near the devices attached to the heatsink (e.g. input diode modules, output transistor modules) and will fault the drive if the temperature reaches 105oC.

An OH Prealarm digital output will close whenever the heatsink temperature reaches the level specified by parameter L8-02. Parameter L8-03 will determine the drive’s response to reaching the OH Prealarm level, in addition to closing the configured digital output.

■ Function: Drive Enabled (Setting: 38)

A iQpump drive Enable digital output will reflect the status of a digital input configured as an iQpump drive Enable input (H1-0x = 6A). If the iQpump drive Enable digital input is closed then the iQpump drive Enabled digital output will also close.

■ Function: Drive Waiting (Setting: 39)

A iQpump drive Waiting digital output will close during the time-out period between the input of a Run command and the expiration of the delay time specified by b1-11.

■ Function: Frequency Reduced, OH (Setting: 3A)

A Frequency Reduced, OH digital output will close when L8-03 = “4:OH Alarm and Reduce” and an overheat pre-alarm is detected.

■ Function: Run from Serial Com (Setting: 3B)

A Run from Serial Com digital output will close when the drive run command is from embedded serial com or the com option card.

■ Function: Pump 2 Control (Setting: 40)

The multi-function digital output is configured to enable a second lag pump based on the normal operating conditions of the iQpump, which determines when the second lag pump should be activated or deactivated. The operation of the digital output is determined by the programming of the Pump Mode selection (P1-01).

If P1-01 = 0, the iQpump is programmed for drive only; therefore, the Pump 2 Control output will be deactivated.

If P1-01 = 1 or 2, the iQpump will activate the Pump 2 Control output based on normal operating conditions.

◆ H3-03 Terminal A1 Bias Setting

Setting Range: -100.0% ~ +100.0%

Factory Default: 0.0%

In order to have the iQpump drive properly interpret an analog input, it may be necessary to apply a gain and / or a bias to the signal. The analog inputs have a resolution of 10 bits (1024 steps). Using the factory default settings for the analog input’s gain and bias, the 0-10 Vdc or 4-20 mA signal at the analog input will yield a 0-100% speed command span.

Figure 1.72

Figure 72. Output Frequency as Commanded Via Analog Input

If a different span of analog input signal is desirable, it will be necessary to adjust the gain, the bias, or both to allow the analog input level to generate the desired frequency command. Adjustment of the gain setting will change the speed command that is equivalent to the maximum analog input (10 Vdc or 20 mA). If, for instance, the gain is increased to 200%, then 10 Vdc or 20 mA will be equivalent to a 200% speed command and 5 Vac or 12 mA will be equivalent to a 100% Speed Command. Since the iQpump drive output is limited by the maximum frequency parameter (E1-04), 0-5 Vdc or 4-12 mA will now be equivalent to 0-100% speed command span.

As a further example, for an inverse-acting speed command, set the bias = 100% and the gain = 0%. The minimum analog input level (0 Vdc or 4 mA) will produce a 100% speed command and the maximum analog input level (10 Vdc or 20 mA) will produce a 0% speed command.

Setting Description

0 0 - 10 Vdc 2 4 - 20 mA (factory default) 3 0 - 20 mA

The H3-08 parameter (Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the A2 analog input. The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a reference. The iQpump drive also has a DIP switch (S1) on the removable terminal board that must be set for the proper reference signal into the A2 analog input. The S1-2 dipswitch setting determines the internal resistance of the A2 input while parameter H3-08 determines how the iQpump drive interprets the measured signal.

The A2 analog input can be programmed to perform many different functions. The setting of parameter H3-09 determines which of the following functions the A2 analog input will perform.

■ Function: Frequency Bias (Setting: 0)

By setting H3-09 = “0: Frequency Bias,” the A2 analog input will serve as a bias signal to the A1 Speed Command. The effect of using A2 for a frequency bias is that the level of the A2 analog input will be summed with the level of the Speed Command analog input (A1). For example, if H3-02 = 100%, H3-03 = 0%, and the A2 analog input level is 1 Vdc, the Speed Command profile will look like Figure 77. below. If A1 = 0 Vdc the Speed Command would be 10% of the programmed maximum frequency because A1 (0 Vdc) + A2 (1 Vdc) = 1 Vdc.

Figure 1.78

H3-02

Bias

109V

Figure 77. Effect of Frequency Bias Function on Speed Command

It should be noted that the bias applied by the A2 analog input functions differently than the level set by the H3-03. If both biases are used simultaneously they will sum together.

The level of the A1 analog input, as a percentage of the maximum input (either 10 Vdc or 20 mA), can be viewed by the U1-15 monitor. The level of the A2 analog input, as a percentage of the maximum input, can be viewed by the U1-16 monitor.

The bias applied by setting H3-09 = “0: Frequency Bias,” can be used in conjunction with the parameter bias H3-03. In that case the H303 bias is applied first which changes the slope of the Speed Command vs. Terminal A1 Voltage graph. Then the level of the A2 analog input is summed with the A1 analog input level, which in effect shifts the Speed Command vs. Terminal A1 Voltage graph upwards or downwards but does not change the slope of the line.

In order for the A2 analog input to be used as the master Speed Command, parameter H3-09 must be set for Aux Reference (H3-09 = “2: Aux Reference”). Once A2 is configured as an auxiliary reference, it can be selected as the master Speed Command by setting H3-13 = “1: Main Fref TA2”. If H3-09 = 2, terminal A2 analog input will become the speed command when a digital input programmed for MultiStep Ref 1 (H1-0x = 3) is selected by a contact closure.

■ Function: PI Feedback (Setting: B)

Configuring the A2 analog input as PI Feedback (H3-09 = “B: PI Feedback”) is a requirement of setting the iQpump drive up for PI operation. The A2 analog input is the only source for feedback for PI operation though the setpoint can come from a number of different sources (refer to the section covering the PI parameters for more information regarding specifying the setpoint source. PI parameters are listed in “b5 PI Function” on page 32).

Parameters H3-10 (Terminal A2 Gain) and H3-11 (Terminal A2 Bias) can be used to configure the A2 analog input to match the signal from the Feedback Transmitter.

The U1-24 monitor (PI Feedback) can be used to check the PI Feedback level with the digital operator.

■ Function: Frequency Bias 2 (Setting: D)

By setting H3-09 = “D: Frequency Bias 2,” the A2 analog input will serve as a bias signal to the A1 Speed Command. This setting functions the same as a setting of H3-09 = 0: Frequency Bias.

■ Function: Motor Temperature (Setting: E)

In addition to or in place of the OL1 (Motor Overload) fault of the drive, it is possible to use a PTC (Positive Temperature Coefficient) thermistor for motor insulation protection. The PTC thermistors are built into the windings of some motors and will vary their resistance based on temperature. An example PTC characteristic is show below.

After the connections are made, configure the A2 analog input for motor temperature protection by setting H3-09 = “E: Motor Temperature”. Parameters L1-03, L1-04, and L1-05 set the response to the alarm level being exceeded, response to the fault level being exceeded, and temperature sensing delay time, respectively.

The proper value of the branch resistance is approximated by the formula:

Normal PI operation will adjust the iQpump drive output in order to match the measured feedback value to a desired setpoint. When PI is operated in the differential mode, however, the iQpump drive output is adjusted in order to maintain a desired differential between two feedback signals. Air handling unit return fan speed control in a “volume snatching” strategy for building pressure control is an example.

When the A2 analog input is configured as a PI Differential (H3-09 = “16: PI Differential”), the A1 analog input becomes the other PI Differential input. The desired differential is set by parameter b5-07 (PI Differential Setpoint) and can be set so that A2 is held less than A1 (b5-07 <0) or A2 is held greater than A1 (b5-07>0).

When PI Differential operation is chosen, the A1 feedback level can be monitored by U1-24 (PI Feedback) and the A2 feedback level can be monitored by U1-53 (PI Feedback2).

■ Function: Not Used (Setting: 1F)

When H3-09 = “1F: Not Used,” any signal applied to the A2 analog input will be ignored by the drive.

An analog input filter can be used to prevent erratic iQpump drive control when a “noisy” analog reference is used. Parameter H3-12 sets the time constant for a first order filter that will be applied to both the A1 and A2 analog inputs. The iQpump drive operation becomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals.

For the A2 analog input to be an effective selection for the H3-13 parameter, parameter H3-09 must be configured as Aux Reference (H3-09 = “2: Aux Reference”).

If H3-09≠2, then the A1 analog input will be used regardless of the setting of parameter b1-12.

The analog output level will correspond to the analog input to the drive’s A2 terminal during normal PI operation but will correspond to the A1 analog input when the A2 analog input is configured as a PI Differential input (H3-09 = “16: PI Differential”). The output will function even if PI operation is not selected (b5-01 = “0: Disabled”). Parameter b5-20 will apply a gain to the measured analog output voltage before the monitor is displayed. (i.e. with b5-20 = 5 the 2 Vdc feedback signal will generate 10 Vdc on the analog output).

The gain and bias parameters for the analog outputs of the iQpump drive allow the programmer to customize the output signal for the equipment connected to the output. The analog outputs are adjustable over a range of 0-10 Vdc. The gain settings for the analog outputs determine the output voltage level that will be equivalent to 100% of the Monitor Function Level. A gain setting greater than 100% will produce 10 Vdc on the analog output when the monitor function is less than 100%.

For example, if H4-02 = 150%, then the FM analog output will produce 6.7 Vdc when the assigned output function initially reached the 100% level.

Like the bias settings for the analog inputs (H3-03 and H3-11), the bias settings for the analog outputs determine the output function level that will be equivalent to 0 Vdc (or 4 mA if the optional terminal board is used).

For example, if H4-03 = -25%, then when the output function level is at 0% the FM analog output will output 2 Vdc.

◆ MEMOBUS / Modbus Communication Configuration

MEMOBUS / Modbus communication is configured using 1 master (PLC) and a maximum of 31 slaves. Serial communication between master and slave is normally initiated by the master and responded to by the slaves.

The master performs serial communication with one slave at a time. Consequently, the slave address of each slave must be individually set, so that the master can perform serial communication using that address. Slaves receiving commands from the master perform the specified functions, and send a response back to the master.

Description

Selects the stopping method when a communication error is detected. 0: Ramp to Stop 1: Coast to Stop 2: Fast-Stop 3: Alarm Only

Enables or disables the communications timeout detection function. 0: Disabled - A communications loss will NOT cause a communications fault. 1: Enabled - If communications are lost for more than the time specified in parameter H5-09, a communications fault will occur.

Sets the time from when the drive receives data to when the drive sends data.

Enables or disables “request to send” (RTS) control: 0: Disabled (RTS is always on) 1: Enabled (RTS turns on only when sending)

Determines how long communications must be lost before a fault is annunciated. Works in conjunction with parameters H5-05 and H5-04.

MEMOBUS / Modbus communication can perform the following operations regardless of the settings in b1-01 and b1-02:

1. Monitoring operation status of the drive

2. Setting and reading iQpump drive parameters

3. Resetting faults

4. Input multi-function commands

Important:

An OR operation is performed between the multi-function command input from the PLC and the command input from multi-function digital input terminals S3 to S7.

■ Message Format

In MEMOBUS / Modbus communication, the master sends commands to the slave, and the slave responds. The message format is configured for both sending and receiving as shown below. The length of the data packets is changed by the command (function) contents.

Slave Address

Set the iQpump drive address from 0 to 32. If 0 is selected, commands from the master will be broadcast (i.e., the iQpump drive will not return responses).

Data

Configure consecutive data by combining the storage register address (test code for a loopback address) and the data the register contains. The data length changes depending on the command details.

Error Check

Errors are detected during communication using CRC-16. Perform calculations using the following method:

1. The factory setting for CRC-16 communication is typically zero, but when using the MEMOBUS / Modbus system, set the factory setting to one (e.g., set all 16 bits to 1).

2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data.

3. Calculate CRC-16 for response messages from the slaves and compare them to the CRC-16 in the response messages.
