◆ 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.
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 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.
If you want 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 3 Setpoint Potentiometer Connection Diagram
Refer to Figure 4 for the connection diagram for an external analog signal setpoint reference.
Note: When b1-01 = 1 (terminals) and P5-01 = 0 (hand mode reference source), the setpoint and the hand reference are
determined by the external analog signal.
Figure 1.4
Figure 4 External Analog Signal Setpoint Reference
If you want the iQpump drive to receive the “Auto Setpoint” from serial communication: Set b1-01 = “2: Serial Com,” and connect
the RS-485/422 serial communications cable to terminals R+, R-, S+, and S- on the control I/O terminal block.
Refer to Figure 5 for the connection diagram using a PC to provide the auto setpoint reference to the iQpump drive. Further information
regarding communication protocols are referenced in Appendix A.

If the Run command is determined by Serial Communications: b1-02 = “2: Serial Communications,” and initiate the Run command
through the serial communications. Refer to Figure 6 (in the previous b1 sequence section) for the connection diagram for serial
communications through the RS232/485 terminals. The following is a simple setup procedure for programming the iQpump drive and PC
Serial communications to initiate Run and Stop commands through serial communications.
1. Program b1-02 = “2: Serial communications”.
2. Program the following H5 parameters:
H5-01 Serial Communication Address: 31
H5-02 Serial Baud Rate: 9600 Baud (setting 3).
H5-03: Serial Communication Parity Selection: None (setting 0)
3. Initiate a Start/Stop command
iQpump command register number: 0001
Stop Command: Transmit value of 0000 (16 bit) to iQpump command address.
Start Command: Transmit value of 0001 (16 bit) to iQpump command address.
Reset Command: Transmit value of 0008 (16 bit) to iQpump command address.
If the Run command input is determined by a network communications option PCB: b1-02 = “3: Option PCB,” and initiate the Run
command through the available network communications option PCB listed below. The Installation Guides (IG) and Technical Manuals
(TM) are available at http://iQpump.yaskawa.com
.

■ Feedback Device
The iQpump Controller requires a feedback device (e.g. Pressure transducer, flow meter, etc.) to perform automatic system regulation.
Any analog 0~10 V or 4-20 mA 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 4~20 mA feedback device connected to
analog input A2.
To successfully operate the iQpump drive remotely, an external run command must be received by the
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 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 Drive.
Figure 1.7
S1
FWD Run/Stop
S2
REV Run/Stop
SN
Figure 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 (> 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.

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.
14 YAS KA WA TM.iQp.02 iQpump Drive Programming Manual
To issue the Run command via a 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
0 Ramp to Stop (factory default)
1 Coast 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.

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.

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.

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).

As a safety precaution, the iQpump drive will not normally respond to a Run input when the digital operator is being used to adjust
parameters. If it is necessary that external Run commands be recognized even while the Drive is being programmed, set b1-08 = “1:
Enabled.”
■ b1-11 Drive Delay Time Setting
Setting Range: 0 to 600 sec
Factory Default: 0 sec
If a time is set into parameter b1-11, the iQpump drive will delay executing any run command until the b1-11 time has expired. During
iQpump drive delay time execution, the digital operator will display:

Both the ALARM and Run indicators will blink while the iQpump drive waits to execute the Run command.
YAS KA WA TM.iQp.02 iQpump Drive Programming Manual 17
◆ 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”).

■ b2-02 DC Injection Braking Current
||
b2-04
t
ime
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 the iQpump drive rated output current. iQpump drive rated output
current is stated on the iQpump drive nameplate.
■ 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 to 10.00 sec
Factory Defaults: b2-03 = 0.00 sec and b2-04 = 0.50 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 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 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 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.
YAS KA WA TM.iQp.02 iQpump Drive Programming Manual 19
◆ 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.

Setting Range: 0 to 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 to 10.0 sec
Factory Default: 2.0 sec
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).
■ b3-05 Speed Search Delay Time
Setting Range: 0.0 to 20.0 sec
Factory Default: 0.2 sec
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
0 Disabled
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.

◆ b4 Delay Timers
The iQpump drive has an internal timer function that operates independently from the Drive. A digital input must be programmed to be a
timer start input by setting H1-0x = 18. A digital output must be programmed as a timer output by setting H2-0x = 12. (Not to be
confused with the “Wait to Run Time” in b1-11.)
■ b4-01 Timer Function ON-Delay Time
Setting Range: 0.0 to 3000.0 sec

The timer start input (H1-0x = 18) must be held on for at least the time specified in parameter b4-01 before the digital output programmed
as the timer output will close. See Figure 20 for timing details.
■ b4-02 Timer Function OFF-Delay Time
Setting Range: 0.0 to 3000.0 sec

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 22 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 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.
26 YAS KA WA TM.iQp.02 iQpump Drive Programming Manual
■ 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 to 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
0 Disabled (factory default)
1Alarm
2Fault
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).
■ b5-13 PI Feedback Loss Detection Level
Setting Range: 0 to 100%
Factory Default: 0%
■ b5-14 PI Feedback Loss Detection Time

The iQpump drive interprets feedback loss whenever the feedback signal drops below the value of b5-13 and stays below that level for at
least the time set into b5-14. See Figure 23 for timing details.

b5-17 PI Accel/Decel Time
Setting Range: 0.0 to 25.5 sec
Factory Default: 0.0 sec
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.

◆ 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)
1Enabled
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 to 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 to 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 to 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).

Factory Defaults: C1-01 and C1-02, 25.0 sec
C1-03 and C1-04, 10.0 sec
C1-05 and C1-06, 50.0 sec
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
further description.
■ C1-09 Fast Stop Time
Setting Range: 0.0 to 6000.0 sec
Factory Default: 10.0 sec
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
further description.
■ C1-11 Accel/Decel Switch Frequency
Setting Range: 0.0 to 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.

◆ C4 Torque Comp
■ C4-01 Torque Compensation Gain
Setting Range: 0.00 to 2.50
Factory Default: 1.00
■ C4-02 Torque Compensation Primary Delay Time
Setting Range: 0 to 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.

◆ C6 Carrier Frequency
■ C6-01 Normal Duty Selection
Setting Description
1 Normal Duty 1
2 Normal Duty 2 (factory default)
Adjustment of parameter C6-01 will affect the Drive’s overload and carrier frequency settings. Generally this parameter does not need
adjustment and should be left at the factory default setting.

Setting Description
0Low Noise
1 Fc=2.0 kHz
2 Fc=5.0 kHz
3 Fc=8.0 kHz
4 Fc=10.0 kHz
F Program
*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 to 4 (10 kHz max.) 1 to 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.

The iQpump drive can be programmed to utilize digital inputs to change between four setpoint and a jog references. It is a two-step
process to set the iQpump drive up for setpoint point and jog references. 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.

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.

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.

Setting the center point of the dead band with the d3-01 through d3-03 parameters and setting the width of the dead band with parameter
d3-04 determines the dead band characteristics. The programmer can set up to three Jump Frequencies. If multiple Jump Frequencies are
programmed the following rule applies:

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 Motor Setup
■ E2-01 Motor Rated Current
Setting Range: 10% to 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.
■ E2-04 Number of Motor Poles
Setting Range: 2 to 48 poles
Factory Default: 2 pole
This parameter sets the number of motor poles used for no-flow detection function and for the calculation of RPM-related parameters.
■ E2-05 Motor Line-to-Line Resistance
Setting Range: 0.000 to 65.000 Ω
Factory Default: Model Dependent
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.)

3Alarm Only
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.
■ F6-05 Current Scaling via Communication Option PCB
Setting Description
0A Display (factory default)
1 100%/8192 (Drive Rated Current)
A communication option card can read the Drive’s DPRAM to access the current monitor. The format of the current reading in the
DPRAM will be determined by parameter F6-05.
F6-05 = “0: A Display” Æ Current is a decimal number corresponding to actual Amperes
F6-05 = “1: 100%/8192 (Drive Rated Current)” Æ Current reading is a number where 8192 = 100% of the iQpump drive rated

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 9 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 b1-02 (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 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: Multi-Acc/Dec 1 (Setting: 7)
When a digital input configured as Multi-Acc/Dec 1 (H1-0x = 7) is OPEN the first set of acceleration/deceleration times (C1-01 and C1-

When a digital input configured as Multi-Acc/Dec 1 (H1-0x = 7) is CLOSED the second set of acceleration/deceleration times (C1-03

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 RampHold (Setting: A)
r
The Acc/Dec RampHold 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 RampHold function is affected by parameter d4-01. If d4-01 = “1: Enabled” and the Acc/Dec RampHold 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/DecRampHold function, if the Acc/Dec
RampHold 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
previous speed command can be reset to the frequency reference lower limit automatically by closing either the UP or Down input
without having a Run command active.
YAS KA WA TM.iQp.02 iQpump Drive Programming Manual 51
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.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: External Fault (Setting: 20 through 2F)
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:
-DRIVE- Rdy

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

• 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.

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.

• 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

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:
Table 14 6B, COM/INV SEL
Option/Inv Function Input Status Run and Speed Command Source
OPEN From the control circuit and analog input terminals (follows b1-01)
CLOSED From Serial Comm port (R+,R-,S+, and S-) (embedded protocols)

• 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

When the digital input is open, the drive will return to normal operation. Refer to the P2 group for further description of the Sleep
function.
Note: Oscillation can occur if Sleep is activated by using the digital input and Sleep Feedback Drop Detection is enabled and
detected. It is recommended to disable Sleep Feedback Drop Level (P2-04) or program a long Sleep Delay Time (P2-03)
and a large Delta Sleep Feedback Drop Level (P2-04).

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 Low Level Input (P1-15). When P1-15 = 0, a Low Water Level Fault will
occur when the contact is closed. An open contact will indicate the drive is operating under normal operating conditions.
When P1-15 = 1, a Low Water Level Fault will occur when the contact is open. 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.
To reset the Low Water Level Fault would require the removal of the run command, initiate a fault reset, and restart the drive using the
Pre-Charge function.
Note: Low Water Level Fault is only active in the Auto Mode and inactive during the Pre-Charge function.

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.

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

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: 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 & 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.

Setting Range: -100.0% to +100.0%

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 61 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.

Adjustment of the bias setting will likewise adjust the speed command that is equivalent to the minimum analog input level (0 Vdc or 4
mA). If, for instance, the bias is set to –25%, then 0 Vdc or 4 mA will be equivalent to a –25% speed command. Since the minimum
speed command is 0% an analog input of 2.5 to10 Vdc or 8 to 20 mA will now be equivalent to 0-100% speed command span.

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 the figure
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.

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.

Function: Aux Reference (Setting: 2)
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 24).
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: PI Differential (Setting: 16)
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.

Parameters H3-10 and H3-11 perform the same function for the A2 analog input that parameters H3-02 and H3-03 perform for the A1
analog input. Please refer to the parameter description for H3-02 and H3-03 for information about H3-10 and H3-11.
These parameters could be used for final calibration of a factory or field installed pressure to electric transducer input connected to
terminal A2 and AC. This field calibration may be needed if there is a job site variation from the typical 3 to 15 PSIG pneumatic signal
input range.
■ H3-12 Analog Input Filter Time Constant
Setting Range: 0.00 to 2.00 sec
Factory Default: 0.30 sec
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.

Parameter H3-13 allows the programmer to select which analog input will serve as the Speed Command input when “Terminals” are
selected as the Auto Mode Speed source (b1-01 = “1: Terminals”), or Terminal is selected as the reference source for the Hand mode (b112 = “1: Terminals”). 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.

Function: Frequency Ref (Setting: 1)
The analog output level will correspond to the chosen Speed Command input whether it is input via the digital operator, analog input, or
serial communication. 100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
Function: Output Freq (Setting: 2)
The analog output level will correspond to the actual Speed being output by the iQpump drive and will include the acceleration and
deceleration ramps. 100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
Function: Output Current (Setting: 3)
The analog output level will correspond to the output current level of the Drive. 100% will be equivalent to the Drives rated output
current which is based on the kVA Rating of the iQpump drive (o2-04).
Function: Output Voltage (Setting: 6)
The analog output level will correspond to the output voltage level of the Drive. 100% will be equivalent to either 200 Vac or 400 Vac
depending on the input voltage rating of the Drive.

SFS (Softstart) Output monitor will not include variations to the Speed Command other than the acceleration and deceleration ramps.
100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
Function: PI Feedback (Setting: 24)
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).
Function: Not Used (Setting: 31)
When H4-01 = “31: Not Used” no voltage is output by the analog output.
Function: PI Input (Setting: 36)
The analog output will correspond to the measured error of the PI function. The measured error of normal PI operation is the setpoint
minus the feedback. The measured error of the differential PI is the difference between the A1 and A2 analog inputs summed with the PI
differential setpoint). The output will not function unless PI operation is selected (b5-01≠0).
Function: PI Output (Setting: 37)
The analog output will correspond to the output of the PI function. The PI output will be measured after any gains, offsets, or limits are
applied to the output of the Proportional and Integral factors. The output will not function unless PI operation is selected (b5-01≠0) and
there is an active Run command. 100% will be equivalent to maximum frequency (E1-04).
Function: PI Setpoint (Setting: 38)
The analog output will correspond to the level of the chosen setpoint of the PI function. Please refer to table on page 25 included in the
section PI Control (b5 parameters) for more information about selecting the PI setpoint source. The output will not function unless PI
operation is selected (b5-01≠0).

78 YAS KA WA TM.iQp.02 iQpump Drive Programming Manual
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.

◆ H5 Serial Communications Setup
This section explains the individual functions used in special applications involving Modbus Communications.
◆ Using Modbus Communication
Serial communication can be performed with Programmable Logic Controllers (PLC’s) or similar devices using the Modbus protocol.
◆ Modbus Communication Configuration
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.

◆ Communication Connection Terminal
Modbus communication uses the following terminals: S+, S-, R+, and R-. The terminating resistance must be turned ON only if the
iQpump drive is at the very end of the Serial Communication chain. Set the terminating resistance by turning ON pin 1 of switch S1 On
the Drives terminal board. Switch S1 is located directly above the left most relay module.

◆ Procedure for Setting Up Communication
Use the following procedure to perform communication with the PLC.
1. Turn OFF the input power to the iQpump drive and connect the communication cable between the PLC and the Drive.
2. Turn ON the input power to the Drive.
3. Set the required communication parameters (H5-01 to H5-09) using the Digital Operator.
4. Turn OFF the input power to the Drive, and check that the Digital Operator display has completely faded.
5. Turn ON the input power to the iQpump drive once again.
6. Perform communication with the PLC.

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 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.

When writing parameters to the iQpump drive from the PLC using Modbus communication, the parameters are temporarily stored in the
constant data area in the Drive. To enable these parameters in the parameter data area, use the Enter command.
There are two types of Enter commands:
1. Enter commands that enable parameter data in RAM
2. Enter commands that write data to EEPROM (non-volatile memory) in the iQpump drive at the same time as enabling data in RAM.
The following table shows the Enter command data. Enter command data can only be written.
The Enter command is enabled by writing 0 to register number 0900H or 0901H.

◆ Modbus Self-Diagnosis
The iQpump drive has a built-in function for self-diagnosing the operations of serial communication interface circuits. The self-diagnosis
function connects the communication parts of the send and receive terminals, receives the data sent by the Drive, and checks if
communication is being performed normally.
Perform the self-diagnosis function using the following procedure.
1. Turn ON the power supply to the Drive, and set parameter H1-05 (Terminal S7 Function Selection) to 67 (Comm Test Mode).
2. Turn OFF the power supply to the Drive.
3. Perform wiring according to the following diagram while the power supply is turned OFF.
4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
5. Turn ON the power supply to the iQpump drive again.
Figure 1.80
Figure 85 Communication Terminal Connection for Self -Diagnosis Function
6. During normal self-diagnostic operation, the Digital Operator displays the frequency reference value. If an error occurs, a CE (Modbus
communication error) alarm will be displayed on the Digital Operator, the fault contact output will be turned ON, and the iQpump
drive operation ready signal will be turned OFF.

Factory Default: 1F 1F 1F
In order for a master to be able to communicate with the iQpump drive using serial communications, the iQpump drive must have a
unique node address. The iQpump drive is given a node address if H5-01¼0. The node addresses do not have to be assigned in sequential
order but they must be unique, i.e. no two Drives on the same serial network can be assigned the same address. After setting the iQpump
drive address with the H5-01 parameter, the power to the iQpump drive must be cycled for the addressing to take effect.
Leaving H5-01 = 0 will disable responses to MEMOBUS communications.

Parameters H5-02 and H5-03 configure the Drives MEMOBUS communications via the RS-485/422 terminals on the removable
terminal block. Configure H5-02 and H5-03 to match the settings of the master controller of the serial network. After changing the H5-02
or H5-03 parameter, the power to the iQpump drive must be cycled for the change to take effect.
If either the speed or parity value is changed via the serial communications, the serial communications will cease to operate until the
iQpump drive power is cycled.
YAS KA WA TM.iQp.02 iQpump Drive Programming Manual 93
It may be necessary to avoid the 19.2 K baud setting if frequent serial communications errors occur at that baud rate.
■ H5-04 Stopping Method after Communication Error
Setting Description
0Ramp to Stop
1Coast to Stop
2Fast-Stop
3Alarm Only (
factory default)
The setting of parameter H5-04 will determine the Drive’s reaction to a serial communications fault such as the CE fault. The iQpump
drive can be programmed to either ramp to a stop in the time specified by C1-02 (H5-04 = “0: Ramp to stop”), coast to a stop (H5-04 =
1), ramp to a stop at the special fast stopping time specified by C1-09 (H5-04 = “2: Fast-Stop”), or continue operating using the
commands received before the serial communication fault and flashing an alarm on the digital operator (H5-04 = “3: Alarm Only”).
■ H5-05 Communications Error Detection Selection
Setting Description
0 Disabled
1 Enabled (
factory default)
The iQpump drive can be configured by parameter H5-05 to recognize a CE fault whenever serial communications time-out. If H5-05 =
“1: Enabled,” the iQpump drive will fault if serial communication responses are not received within a set period of time determined by
parameter H5-09. iQpump drive power should be cycled after a change is made to this parameter.
■ H5-06 Drive Transit Wait Time
Setting Range: 5 to 65 ms
Factory Default: 5 ms
Parameter H5-06 will set the delay time between the receiving of a message from the master and the sending of a response from the
iQpump drive back to the master. The iQpump drive power should be cycled after a change is made to this parameter.
■ H5-07 RTS Control Selection
Setting Description
0 Disabled (RTS is always on)
1 Enabled (RTS turns on only when sending) (
factory default)
RTS or Request To Send control is a method of flow control applied to messaging in serial communications. Parameter H5-07 configures
whether the iQpump drive will implement RTS messaging all the time (H5-07 = “0: Disabled”) or only when sending (H5-07 = “1:
Enabled”). It is recommended to set H5-07 = “0: Disabled,” when using RS-485 and set H5-07 = “1: Enabled,” when using RS-422. The
iQpump drive power should be cycled after a change is made to this parameter.
■ H5-08 Communication Protocol Selection
Setting Description
0 Memobus (Modbus) (
1 N2 (Metasys)
2 FLN (APOGEE)
factory default)
Since the iQpump drive is capable of using MEMOBUS, Metasys N2, or Apogee FLN communications via the RS-485/422 terminals,
parameter H5-08 must be programmed to specify to the iQpump drive which format is being used. iQpump drive power should be cycled
after a change is made to this parameter.
94 YAS KA WA TM.iQp.02 iQpump Drive Programming Manual
■ H5-09 Communication Error Detection Time
Setting Range: 0.0 to 10.0 sec
Factory Default: 2.0 sec
The setting of parameter H5-09 determines the length of time that serial communications must be lost before a CE fault occurs. Setting
H5-09 = 0 will configure the iQpump drive for the quickest CE fault detection but may cause nuisance faults. The iQpump drive power
should be cycled after a change is made to this parameter.

◆ L1 Motor Overload
■ L1-01 Motor Overload Protection Selection
Setting Description
0 Disabled
1 Std Fan Cooled (Enabled) (
The iQpump drive has an I2t electronic overload protection function, the OL1 fault, for protecting the motor from overheating. The
iQpump drive bases the protection on time, output current, and output frequency. The electronic thermal overload function is ULrecognized so an external thermal overload relay is not required.
If the iQpump drive is connected to a single motor, the motor overload protection should be enabled (L1-01 = “1: Std Fan Cooled”)
unless another means of preventing motor thermal overload is provided.
The time before the OL1 fault will occur changes as the output frequency is reduced. The maximum output current level at which there is
no time limit for operation (the OL Start Point) is different depending on the output frequency. For instance, if the iQpump drive is being
operated at 60 Hz and the output current level is below 106% of the motor’s rated current (E2-01), the iQpump drive will run without an
OL1 fault indefinitely. Once the 106% output current level is exceeded, de-rating of the OL1 time starts.

Important: If the iQpump drive is connected to more than one motor for simultaneous operation, the electronic overload protection
should be disabled (L1-01 = “0: Disabled”) and each motor should be wired with its own motor thermal overload.
■ L1-02 Motor Overload Protection Time
Setting Range: 0.1 to 20.0 Minutes
Factory Default: 8.0 Minutes
The L1-02 parameter will set the allowed operation time before the OL1 fault will occur when the iQpump drive is running at 60 Hz and
133% of the motor’s full load amp rating (E2-01). Adjusting the value of L1-02 can shift the set of OL1 curves up the Y-axis of the
diagram below but will not change the shape of the curves.

The iQpump drive can be programmed to accept a PTC (Positive Temperature Coefficient) Thermistor input for monitoring motor
temperature. By setting parameter H3-09 = “E: Motor Temperature,” and attaching the PTC thermistor per the figure below, the iQpump
drive can react to the increasing motor winding temperature with both an alarm (L1-03) and a fault (L1-04).

Using the changing voltage drop across the thermistor the voltage into the A2 analog input will vary according to the motor’s winding
temperature. If the measured voltage into A2 exceeds 1.17 Vdc the iQpump drive will flash an OH3 alarm on the digital operator and will
either ramp to a stop in the time specified by C1-02 (L1-03 = “0: Ramp to Stop”), coast to a stop (L1-03 = “1: Coast to Stop”), ramp to a
stop at the special fast stopping time specified by C1-09 (L1-03 = “2: Fast-Stop”), or continue operating using the commands received
before the OH3 alarm (L1-03 = “3: Alarm Only”). The Drive’s fault contact, MA-MB, will not close.
If the measured voltage into the A2 analog input exceeds 2.34 Vdc the iQpump drive will fault (OH4) and either ramp to a stop in the
time specified by C1-02 (L1-04 = “0: Ramp to Stop”), coast to a stop (L1-04 = “1: Coast to Stop”), ramp to a stop at the special fast
stopping time specified by C1-09 (L1-04 = “2: Fast-Stop”). The Drive’s fault contact, MA-MB, will close.
Parameter L1-05 will apply a time delay filter to the A2 analog input when it is configured as the thermistor input. The greater the time
programmed into L1-05 the less responsive the iQpump drive will be to quick changes to the input voltage but the more stable the input
will be. A noisy input will benefit from a greater L1-05 time.

◆ L2 Momentary Power Loss Ride-thru Function
When momentary power loss recovery is enabled (L2-01≠0), a speed search is executed to catch the potentially spinning motor shaft.
This speed search will occur regardless of the setting of b3-01 “Speed Search Selection”.
■ L2-01 Momentary Power Loss Detection Selection
Setting Description
0 Disabled
1PwrL Ride Thru t
2 CPU Power Active (
■ L2-02 Momentary Power Loss Ride-Thru Time
Setting Range: 0.0 to 25.5 sec
Factory Default: Model Dependent
The iQpump drive allows different responses to momentary power losses. The setting of L2-01 determines whether the iQpump drive
attempts to restart after a short loss of incoming AC power and for what length of time this capability remains active.
If L2-01 = “0: Disabled,” the iQpump drive detects a UV1 fault 15 ms after power loss and automatic restarting is disabled. The iQpump
drive cannot restart until the external run command is removed and the UV1 fault is reset.
If L2-01 = “1: PwrL Ride Thru t,” the iQpump drive restarts without the UV1 fault if power is returned within the time specified in L202, the Momentary Power Loss Ride-thru Time. During the power loss but before the fault trip, the digital operator will display a UV
alarm. If L2-02 is set for a time longer than the control power supply can be sustained, a UV1 fault will not occur and the iQpump drive
restarts upon the return of AC power. The time that the control power supply can be maintained varies with iQpump drive size. The larger
the Drive, the greater the potential ride-thru time.
If L2-01 = “2: CPU Power Active,” the iQpump drive ignores L2-02 and attempts a restart as long as the control power supply is still able
to maintain a minimal voltage level. In effect, setting L2-01 = “2: CPU Power Active” (factory default) is programming the iQpump
drive for maximum Power Loss Ride-thru. An equivalent setting is L2-01 = “1: PwrL Ride Thru t,” with L2-02 set to a time longer than
the control power supply can be maintained after power is lost.
factory default)
Note: The run command must be held during power loss for any power loss ride-thru capability to be possible. It is for this
reason that 3-wire control is not recommended for use with the Momentary Power Loss function.
■ L2-03 Momentary Power Loss Minimum Baseblock Time
Setting Range: 0.1 to 5.0 sec
Factory Default: Model Dependent
When momentary power loss recovery is enabled (L2-01¼0) the iQpump drive will baseblock for a period of time specified by the L2-03
parameter. The baseblock time will be executed just prior to the speed search function in order to allow any residual magnetic fields in
the motor windings to decay before any new voltage is applied to the motor.
If the motor’s secondary circuit time constant is known, set L2-03 = 0.7x (value of time constant). If an OC or OV fault occurs during
momentary power loss recovery, increase the setting of L2-03.
The L2-03 parameter also sets the baseblock time for the DC Injection Braking function (b1-03 = “2: DC Injection to Stop”). If an OC or
OV fault occurs during DC Injection Braking to Stop, increase the setting of L2-03.
YAS KA WA TM.iQp.02 iQpump Drive Programming Manual 99
■
L2-04 Momentary Power Loss Voltage Recovery Ramp Time
Setting Range: 0.0 to 5.0 sec
Factory Default: Model Dependent
When momentary power loss recovery is enabled (L2-01≠0), a speed search is executed to catch the potentially spinning motor shaft. As
part of the speed search function full voltage is not immediately applied to the motor but is ramped up. The setting of parameter L2-04
determines the ramp time for increasing the output voltage from zero to maximum voltage (E1-05).
If a UV1 fault occurs during the current detection speed search function, increase the setting of L2-04.
■ L2-05 Undervoltage Detection Level
Setting Range: 150 to 210 Vdc
Factory Default: 190 Vdc
The L2-05 parameter sets the DC Bus undervoltage level. The setting of L2-05 affects the voltage at which a UV alarm or a UV1 fault
will occur. If the setting of L2-05 is lowered below the factory default level (190 Vdc for a 240 Vac drive and 380 Vdc for a 480 Vac
drive), then an AC Input Reactor must be installed on the input AC line to prevent inrush current from damaging the Drive’s input diodes.
An AC Line dip and fast voltage recovery can potentially cause a large inrush current.
