Check the model number on the nameplate on the right side of the iQpump drive. Reconcile with packing slip and/or order information.

Inspect the entire exterior of the iQpump drive to see if there are any dents, scratches or other damage resulting from shipping.

◆ Nameplate Information

A nameplate is attached to the right side of each iQpump drive. The following nameplate is an example for a standard iQpump drive.

1.6 Checking and Controlling the Installation Site

Install the iQpump drive as described below and maintain optimum conditions.

WARNING

The iQpump drive heatsink temperature may exceed 158°F (70°C). Therefore, mount the iQpump drive to a surface suitable for high temperature.

◆ Installation Site

Locate the iQpump drive as close as possible to the motor. Install the iQpump drive under the following conditions in UL Pollution Degree 1 & 2 environments. This excludes wet locations where surfaces may become conductive due to moisture and contaminant loading.

Table 1.5 Installation Site Specifications

Typ e Ambient Operating Temperature Humidity Plenum Rated

NEMA Type 1 14°F-to 104°F (-10-to 40°C) 95%-RH-or-less-(no-condensation) Yes

Open Chassis 14°F-to 113°F (-10 to +45°C) 95%-RH-or-less-(no-condensation) No

Protective covers are attached to the top and bottom of the iQpump drive. It is recommended to remove the protective covers before operating a CIMR-P7U2030/4055-107 iQpump drive and smaller in a panel to obtain the 113°F (45°C) ambient operating temperature.

Observe the following precautions when installing the iQpump drive:

• in a clean location which is free from oil mist and dust.

• in an environment where metal shavings, oil, water, or other foreign materials will not get into the iQpump drive enclosure.

• in a location free from radioactive materials.

• in a location free from harmful gasses and liquids.

• in a location free from excessive vibration.

• in a location free from chlorides.

• in a location away from direct sunlight.

• on a non-combustible surface.

◆ Controlling the Ambient Temperature

To enhance the reliability of operation, the iQpump drive should be installed in an environment free from extreme temperature variations. If the iQpump drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature below 113° (45°C).

◆ Protecting the iQpump Drive from Foreign Matter

During iQpump drive installation and project construction it is possible to have foreign matter, such as metal shavings or wire clippings, fall inside the iQpump drive. To prevent foreign matter from falling into the iQpump drive, place a temporary cover over the iQpump drive.

Always remove the temporary cover from the iQpump drive before Start-Up. Otherwise, ventilation will be reduced, causing the iQpump drive to overheat.

22 YASKAWA TM.iQp.01 iQpump Drive User Manual

1.7 Installation Orientation and Clearances

Install the iQpump drive vertically so as not to reduce the cooling efficiency. When installing the iQpump drive, always provide the following installation clearances to allow normal heat dissipation. For 3HP, 208V/240V (CIMR-P7U22P2-107 and below) or 2HP, 480V (CIMR-P7U41P-107 and below), ensure that the heatsink is against a closed surface to avoid diverting cooling air around the heatsink.

2.2 Wiring Main Circuit Terminals

■ Cable Length Between iQpump Drive and Motor

The iQpump should be installed as close as possible to the motor to minimize the length of load side power cable needed between the iQpump drive and the motor.

If the cable between the iQpump drive and the motor is long, the high-frequency leakage current will increase, causing the iQpump drive output current to increase as well. This may affect peripheral devices. To prevent this, reduce the cable length whenever possible, or if necessary, adjust the carrier frequency (set in C6-02) as shown in Tab le 2. 6.

The line side power cables, load side power cables and the control wiring should all be run in a separate conduit. Careful attention to this recommended design practice will avoid many potential motor and iQpump drive related problems.

Table 2.6 Motor Cable Length vs. Carrier Frequency (C6-02)

Motor Cable Length 328ft. (100m) maximum More than 328ft. (100m)

Carrier Frequency 10kHz maximum 5kHz maximum

(See the limitations on carrier frequency, based on iQpump drive capacity and model number in Appendix B).

Ground Wiring

■

Observe the following precautions when connecting the ground wire:

1. 208-240 VAC iQpump drives should have a ground connection with resistance of less than 100Ω.

2. 480 VAC iQpump drives should have a ground connection with resistance of less than 10Ω.

3. Do not share the ground wire with other devices, such as motors or large-current electrical equipment.

4. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the iQpump drive. Therefore, if the distance between the ground rod and the ground terminal is too long, potential on the ground terminal of the iQpump drive will become unstable.

5. When using more than one iQpump drive, be careful not to loop the ground wire. See Figure 2.4.

NOT OK

Figure 2.2 Ground Wiring Examples

■ Control Circuit Ground Terminals

The removable iQpump drive control terminal card provides two ground terminals (marked TB3 and TB4) to accept the control wire shield connection. The control wire shield should be connected on this end only, the opposite end should be isolated with electrical tape.

IMPORTANT

Grounding of the iQpump enclosure and motor is required for proper system operation.

YASKAWA TM.iQp.01 iQpump Drive User Manual 39

2.3 Control Wiring

◆ Control Circuit Wire Sizes

The auto mode setpoint (speed command) field wiring connection is made to iQpump drive terminals A1 or A2 (signal positive), AC (signal common) and G (shield). Keep this lead length as short as possible to maintain signal quality. Insulated twisted shielded pair wire (2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same conduit as other AC power or control wires. The shield must be connected on this end only, stub and isolate the other end. The A2 signal employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA.” For 0 to 10 Vdc, parameter H3-08 is set for “0: 0 - 10 Vdc” and the iQpump control board DIP switch S1-2 must be in the OFF position. (See Figure 2.4).

For remote operation, keep the length of the control wiring to 50m or less. Separate the control wiring from high-power lines (input power, motor leads or relay sequence circuits) to reduce noise induction from peripheral devices.

When setting speed commands (frequency references) from an external speed potentiometer (and not from the Digital Operator), use shielded twisted-pair wires and ground the shield to terminal E(G), as shown in Figure 2.3. Terminal numbers and wire sizes are shown in Table 2.7.

Step

 1. The iQpump drive is thoroughly tested at the factory. The start up person should verify that the iQpump drive is free of shipping

and installation damage. Shipping damage is not covered by the Yaskawa warranty. Claims must be filed with the shipping company as soon as possible for any potential recovery via insurance.

 2. Review the iQpump (P7U) User Manual (TM.iQp.01) shipped with the iQpump drive.

 3. Verify that the model number and voltage ratings in the purchase order match the nameplate data for each unit.

 4. Location of the iQpump drive is important to achieve proper performance and normal operating life. The unit should be installed

in an area where it is protected from:

Direct sunlight, rain or moisture Corrosive gases or liquids Vibration, airborne dust or metallic particles

 5. Ensure the iQpump drive is on a vertical surface with adequate space for air circulation (4.75” above and below, 1.2” on each

side). Refer to Figure 1.5.

 6. Verify that the proper branch circuit protection is installed in front of the iQpump drive. Refer to Appendix E Peripheral

Devices for proper input fuse or circuit breaker sizing.

 7. Avoid running input and output wiring in the same conduit.

 8. Avoid routing power wiring near equipment sensitive to electrical noise.

66 YASKAWA TM.iQp.01 iQpump Drive User Manual

4.1 Start Up

 9. Never allow wire leads to touch metal surfaces. Short-circuit may result.

 10. Never connect AC main power output terminals U/T1, U/T2 and W/T3.

 11. Never connect power factor correction capacitors or noise filters to the iQpump drive output.

 12. Use 600 Vac vinyl-sheathed wire or equivalent. Wire size should be determined considering voltage drop of leads.

Line voltage drop (V) =

x wire resistance (Ω/km) x wire length (m) x current (A) x 10

-3

 13. It is recommended that the motor lead length not exceed 164 feet (50 meters) and motor wiring be run in a separate conduit from

the power wiring. If lead length must exceed this distance, reduce the carrier frequency (see Figure 2.6) and consult Yaskawa toll free at 1-800-YASKAWA (927-5292) for other motor protection measures.

 14. Signal and control leads must be separated from main circuit leads (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3).

 15. Determine proper wire size for power and motor leads. Refer to Table 2.1 and Table 2 . 2 for details.

 16. Review proper ground connections for the iQpump drive. Refer to Chapter 2 for details. The iQpump drive must be solidly

grounded using the main circuit ground terminal. Ground resistance should be less than 100Ω for a 208-240 Vac iQpump drive. Ground resistance should be less than 10Ω for a 480 Vac iQpump drive. Select wire size suitable for the size of terminal screw. Make the length as short as possible.

Never ground the iQpump drive in common with welding machines, motors or other large-current electrical equipment.

Where several iQpump drives are used, ground each iQpump drive directly or daisy-chain to the ground pole(s). DO NOT FORM A LOOP WITH THE GROUND LEADS. See Table 2.4.

 17. Review terminal functions of signal and control circuits. Refer to Table 2.8.

 18. Verify if any customer safety devices are required (e.g. External Pump Fault).

 19. Record the following motor nameplate information:

Voltage: _____________________Motor Rated Amps: ____________________

 20. Verify that the commercial power supply is within the rated iQpump drive input voltage:

Power Supply: ____________________VAC Drive Input Voltage: ____________________VAC

 21. Verify that the leads in the 3-Phase electric motor conduit box are configured for the proper voltage.

 22. Ensure Motor Rated Current is less than or equal to iQpump drive Output Amps. If multiple motors are being used, make sure

that the Motor Rated Current sum is less than or equal to iQpump drive Output Amp rating. Please note that if multiple motors are being operated from one iQpump drive, each motor must have its own overload and short circuit protection.

 23. Wire all necessary power leads to the iQpump drive. DO NOT CONNECT MOTOR TO iQpump DRIVE YET.

 24. Wire all necessary ground wires to the iQpump drive.

YASKAWA TM.iQp.01 iQpump Drive User Manual 67

4.1 Start Up

 25. Wire all necessary control wires to the iQpump drive.

 26. Ensure that the power leads are connected to the R/L1, S/L2 and T/L3 terminals in the iQpump drive.

 27. Tighten all of the three-phase power and ground connections. Please check that all control and signal terminations are tight.

 28. Inspect the control circuit connections (including the shield) and determine if a motor “safety circuit” is connected.

If normally closed, these contacts may be wired in series with the RUN command contacts, which are between terminals S1 and SN of the iQpump drive. No special programming is required. Refer to Chapter 2.

Alternately, these contacts could be wired between terminals S3 and SN as External Fault Inputs, and may be either normally closed or normally open contacts.

 29. Record any other connections to the iQpump drive using the blank terminal connection drawing in Chapter 2 – Electrical

Installation (Fig. 2.9) to determine if special programming is required for the following:

Multi-function Inputs – refer to Appendix A.

Multi-function Outputs – refer to Appendix A.

Multi-function Digital Inputs – refer to Appendix A.

Multi-function Analog Outputs – refer to Appendix A.

Serial Communications – refer to Appendix A.

The installed feedback device requires the proper scaling. For proper installation of the feedback device, refer to Chapter 3. The feedback scaling is determined by programming the feedback device scaling parameter P1-03.

To make setting up the feedback scaling easier, first select the actual system units desired for the iQpump drive to regulate. The system units can be selected by programming the desired units in parameter P1-02.

The feedback range can be specified with one single parameter: P1-03 Feedback Device Scaling. The maximum feedback value for the iQpump is 3600 (PSI, GPM, etc.).

If the monitors seem more natural in terms of PSI, set P1-02 = 1.

If another engineered unit, such as WC (Inches of Water) or GPM (Gallons per Minute), is desired, set P1-02 to the appropriate value. The setting programmed in the Feedback Device Scaling (P1-03) will determine the display at 100% and the position of the decimal point.

The iQpump drive has a built-in function that allows the system to start regulating when the feedback signal drops below a programmed start level (P1-04) for a programmed start level delay time (P1-05).

In many constant pressure applications, it is necessary to start the pump at different feedback levels along with a timer to ensure that the pump does not cycle on and off, if the pressure is floating too close to the start level. Due to system losses and leaks in pipes, the pressure will slowly decrease and it is desirable for the iQpump drive system to sense this changing level and automatically restart the automatic regulation back to desired setpoint.

Example: Constant Pressure System

System Units set to PSI (P1-02 = PSI) System Setpoint set for 80 PSI Pressure Transducer: 150 PSI

Desired Operation:

Pump System should start regulating when pressure drops below 70 PSI.

Solution:

Program P1-04 to 70 PSI and P1-05 to 2 sec.

The iQpump drive offers dedicated functions to protect the pump system from possible occurrences. The following section explains the basic pump protection that the iQpump drive offers. One or more of the basic protection functions can protect from occurrences such as:

•Dry Well

•Air in System

• Blocked Impeller

•No Water

• Low Feedback (e.g. Low System Pressure Detection)

• High Feedback (e.g. High System Pressure Detection)

◆ Pump System Shutdown When System Setpoint Cannot Be Maintained

The iQpump drive continuously monitors pump system regulation and is able to shutdown the pump system after a programmable time in case the system is not able to maintain the system setpoint. The Pump Protection function consists of 2 parameters:

Description

When the Drive is running and the difference between the setpoint and the feedback exceeds the level in P1-11 for the time specified in P1-12, the Drive will trip on a “Not Maintaining Setpoint (NMS)”. The Drive will coast to a stop when a fault occurs. A value of 0 disables this function. This function is only active during running while operating in auto mode.

Delay time before a Not Maintaining SetPoint or Loss of Prime Time fault occurs. Pump protection criteria specified in P1-11 or P1-14 must be met for the Drive to fault. The Drive will coast to a stop when a fault occurs. A value of 0 disables both Loss of Prime and Not Maintaining SetPoint faults.

The iQpump drive can be configured to display a Not Maintaining Setpoint (NMS) fault when the difference between the setpoint and the feedback exceeds the Maximum Setpoint Difference (P1-11). When the Maximum Setpoint Difference has been exceeded, the drive will trip on NMS fault and will coast to a stop when the fault occurs.

Setting P1-11 to a value of 0 will disable this function. This function is only active during operation in the Auto Mode.

The Maximum Setpoint Difference (P1-11) works in conjunction with the Not Maintaining Setpoint and Loss of Prime Time (P1-12). The units for this parameter are determined by the System Units (P1-02)

■ P1-12 Not Maintaining Setpoint and Loss of Prime Time: (Factory Default is 60 sec.)

The iQpump drive can be configured to display a Maximum Setpoint Difference (P1-11) fault when the difference between the setpoint and the feedback are exceeded for the time programmed in the Not Maintaining Setpoint and Loss of Prime Time (P1-12). The drive will coast to a stop after the level has been exceed for the specified time programmed in P1-12.

This function is only active during operation in the Auto Mode.

The Not Maintaining Setpoint and Loss of Prime time (P1-12) is also used for the Prime Loss Level (P1-14) function. refer to Prime Loss Level (P1-14) for further description.

The Not Maintaining Setpoint and Loss of Prime Time (P1-12) works in conjunction with Maximum Setpoint Difference (P1-11) and Prime Loss Level (P1-14).

Note: The time value programmed into P1-12 is shared by Maximum Setpoint Difference (P1-11) and Prime Loss Level _(P1-14) functions. However, independent times are maintained. If one function time, such as P1-11, has elapsed, the other functions time (P1-14) is still maintained until this time has elapsed.

2 Serial Com - RS-485 Terminals R+, R-, S+ and S-

3 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.

If you want 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 U1-01 monitor parameter in the “-DRIVE-” Menu.

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. Please refer to Section 4.1 Start Up for further set up details.

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

If you want the iQpump drive to follow an “Auto Set-Point” 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.

• Modbus TCP/IP Option Card CM090 Manual: IG.AFD.25

• EtherNet/IP Option Card CM092 Manual: IG.AFD.26

■ Feedback Device

The iQpump Controller requires a feedback device (e.g. Pressure transducer, flow meter, etc.) to perform automatic system regulation. Any analog 0~10V or 4-20mA feedback device can be used in combination with the iQpump controller.

Connecting Your Feedback Device to the iQpump Controller

Note: The factory default setting for the iQpump controller is 4~20mA feedback device connected to

analog input A2.

To successfully operate the iQpump drive remotely, an external run command must be received by the iQpump drive. Parameter b1-02 specifies from where the run command will be accepted.

Although the Run Source and the Reference Source (b1-01) are normally taken from the same source (e.g. digital operator, terminals or serial communication), this is not always the case.

To issue a run command from the digital operator: Set b1-02 = “0: Operator,” and use the HAND and OFF buttons to start and stop the iQpump drive.

To issue the run command from the terminals: Set b1-02 = “1: Terminals,” and 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 iQpump drive.

REV Run/Stop

Figure 5.7 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 (> 50 mS) 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 S5 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.

To issue a Run command via serial communication: Set b1-02 = “2: Serial Com” and connect the RS-485/422 serial communication cable to R+, R-, S+, and S- on the removable terminal block.

To issue the Run command via the network option card: Set b1-02= “3: Option PCB”, and plug a network option board (p/n SI/J) into the 2CN port on the Control PCB. Consult the manual supplied with the option board for instructions on integrating the iQpump drive into your network System.

Important: If b1-01= “3: Option PCB” but a network card is not installed in 2CN, an “OPE05” operator programming error will be displayed on the digital operator and the iQpump drive will not run.

■ b1-03 Stopping Method

There are four methods of stopping the iQpump drive when the Run command is removed.

Setting Description

0Ramp to Stop (factory default)

1Coast to Stop

2 DC Injection to Stop

3Coast w/Timer

0: Ramp to stop: When the Run command is removed, the iQpump drive will decelerate the motor to 0 rpm. The rate of deceleration is 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.

◆ b2 DC Braking

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 to 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 5.13 DC Injection Braking During Stopping

■ b2-02 DC Injection Braking Current

Setting Range: 0 to 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 iQpump drive rated output current. The iQpump drive rated output current is stated on the iQpump drive nameplate.

■ b2-03 DC Injection Braking Time at Start

b2-04 DC Injection Braking Time at Stop

Setting Range: 0.00 to 10.00 sec Factory Default: b2-03 = 0.00 sec

b2-04 = 0.00 sec

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 iQpump 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.

Figure 5.11

Output Frequency

DC injection

b2-03 b2-04

Figure 5.14 DC Injection Braking During Starting and Stopping

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 to 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 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.

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 iQpump drive.

The PI setpoint can be configured to come from one of many different inputs or parameters. Table 5.1 on page 99 describes the options for originating the PI setpoint.

In some situations there are two feedback inputs. The iQpump 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).

Setting Description

0 Disabled (factory default)

1Enabled

3Fref+PI

The iQpump drive can be used as a stand-alone PI controller. If PI functionality is selected by parameter b5-01, the iQpump drive will adjust its output to cause the feedback from a transmitter to match the PI setpoint (b5-19). The setting of b5-01 will determine whether PI functionality is disabled (b5-01 = “0: Disabled”), enabled (b5-01 = “1: Enabled”), or enable with the output of the PI function used to trim a Speed Command (b5-01 = “3: Fref+PI”).

■ b5-02 Proportional Gain Setting

Setting Range: 0.00 to 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 5.16 on following page).

■ b5-03 Integral Time Setting

Setting Range: 0.0 to 360.0 sec Factory Default: 5.0 sec

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.

■ b5-04 Integral Limit Setting

Setting Range: 0.0 to 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 to 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 iQpump drive’s response to error (the difference between the setpoint and the feedback).

■ b5-07 PI Offset Adjustment

Setting Range: -100.0% to +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.

■ b5-08 PI Primary Delay Time Constant

Setting Range: 0.00 to 10.00 sec Factory Default: 0.00 sec

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.
