WARNING
• Read and understand this manual before installing, operating, or servicing this drive. All warnings, cautions, and
instructions must be followed. All activity must be performed by qualified personnel. The iQpump drive must be
installed according to this manual and local codes.
• Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the
power is on. Do not remove or insert the digital operator while power is on.
• Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power
supply is turned off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus
voltage is below 50 Vdc. To prevent electric shock, wait at least five minutes after all indicators are OFF and
measure DC bus voltage level to confirm safe level.
• Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be
damaged by high voltage.
• The iQpump drive is not suitable for circuits capable of delivering more than 100,000 RMS symmetrical amperes.
Install adequate branch short circuit protection per applicable codes. Refer to the specification. Failure to do so may
result in equipment damage and/or personal injury.
• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices

b1 Sequence
The Sequence Group contains parameters associated with starting and stopping the drive. Parameters involving the Run Command, Speed
Reference location, Stopping Method and Hand / Auto changeover are located in this group.
◆ b1-01 Reference (Auto Setpoint) Source Selection
Setting Description
0 Operator - Digital Preset Setpoint d1-01 (factory default)
1 Terminals - Analog Input Terminal A1 (or Terminal A2, see Parameter H3-13)
2 Serial Com - RS-485 Terminals R+, R-, S+ and S3 Option PCB - Option Board connected at 2CN
In order to run the iQpump drive and motor, the iQpump drive must receive a Run command and a Auto Setpoint command. Parameter
b1-01 specifies from where the Auto Setpoint is received when in the “Auto” mode. Switching into the “Auto” mode can be done by
pressing the AUTO button on the digital operator while the iQpump drive is stopped.
Important: If a Run command is input to the iQpump drive but no corresponding Auto Setpoint is input, the Run indicator on the digital
operator will turn on and the STOP indicator on the digital operator will blink.
To configure the iQpump drive to follow the “Hand Reference” set by the digital operator: Use the “Hand” mode by pressing the
hand key and set P5-01 = “1: Hand Reference (P5-02)”. The hand reference can then be entered into the P5-02 parameter.
The iQpump drive offers the ability to provide four types of “Auto Setpoint” reference sources. These Auto Setpoint reference sources are
determined by the setting of b1-01 and the drive set to “Auto” mode by pressing the Auto key on the digital operation.
Note: Prior to programming, it is recommended to first select the system units (P1-02) and the feedback device, Scaling
(P1-03). P1-03 will automatically scale the iQpump Setpoint.
Example:
P1-02 = 1: psi
P1-03 = 200, feedback range = 200 psi.
To configure the iQpump drive to follow an “Auto Setpoint” set by the digital operator: Set b1-01 = “0: Operator” (factory default),
The Auto Setpoint can then be entered into the U1-01 monitor parameter in the “-DRIVE-” menu.
Figure 1.2
Figure 2. Digital Operator Auto Setpoint
To configure the iQpump drive to follow an “Auto Setpoint” set by the analog input: Set b1-01 = “1: Terminals,” and connect a
potentiometer or external signal to the iQpump drive. Refer to Figu re 3. for connection diagram for the setpoint potentiometer.

b1-02 = 0, Operator (factory default).
The iQpump drive comes factory programmed for Start and Stop from the Keypad.
The iQpump drive can be programmed to receiver a Run command from four different inputs: digital operator, terminals, serial
communications, or an option PCB.
If the Run command input is determined by the digital operator: Set b1-02 = “0: Operator,” and the HAND and OFF keys will be
used to provide the Run command to the iQpump drive.
b1-02 = 1, Terminals
If the Run command input is determined by the external terminals: Set b1-02 = “1: Terminals” and initiate an external Run
command by a contact closure between terminals S1 and SN. Refer to Figure 8. for the connection diagram of the external Run
command.
Note: To use the external terminals requires the iQpump drive to be set to “Auto” mode by pressing the Auto key.
Select between 2-wire and 3-wire control operation by doing the following:
2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN will be
interpreted as a Forward Run command by the drive.
Figure 1.6
Figure 6. 2-Wire Control
3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and S2 become
Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward / Reverse input for the iQpump
drive. When the Forward / Reverse input is open the iQpump drive will run in the Forward direction and when the input is closed, the
iQpump drive will run in the Reverse direction.
In 3-wire operation a momentary closure (> 50mS) of S1 will cause the iQpump drive to run provided that S2 is held closed. The iQpump
drive will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization (A1-03 =
“3330: 3-Wire Initial”), then terminal S3 becomes the Forward / Reverse input.
Note: Reverse operation is disabled in the iQpump drive; however, in 3-wire control, one of the multi-function digital inputs
needs to be programmed to 0. Otherwise, the 3-wire control will not work.

• Only enabled when all three Run / Stop Control parameters are set to a value greater than zero (P4-18 > 0, P4-19 > 0, and P4-20 > 0).
• Available only when in HAND or LOCAL mode.
• PI control is disabled.
• Will always start off running when a run command is given.
• A stop command, power loss or fault will reset all timers and counters associated with the Run / Stop Control.
• A stop command will result in a stopping method set by parameter b1-03.
• When the “Run” portion of the timer expires, the drive stop using the stopping method set by parameter b1-03.
• When stopped due to the “Run” timer expired, the standard “sleep” message will be displayed on the operator.
• When stopped because the final cycle count has been exceeded, the digital operator will display “Run / Stop Finished”. The display
will be cleared when a stop command is given or power is lost.
• If a fault (not auto-restart) occurs during Run / Stop Control, all timers and counters are reset.
• If an auto-restart is in process, under most circumstances the Run / Stop Control will continue to operate. However, if the stop timer
expires prior to the auto-restart expiring, the drive will wait until the auto-restart time expires before resuming normal Run / Stop
Control.
When this feature is enabled and the drive is given a run command, the drive will run for the time specified in parameter P4-18, then stop
for the time specified in parameter P4-19. It will do this the number of times programmed in parameter P4-20. (Refer to parameters P418, P4-19 and P4-20.) The display will show one of two messages if the drive is stopped due to this feature. Run-Stop control cannot be
enabled when a multiplex mode (P1-01 > 0).
Timed Run:
If parameter b1-02 is set to 5 “Timed Run”, the timed run feature will be enabled. When “Timed Run” is enabled, Terminal S1 will be a
normally open “start” input and Terminal S2 will be a normally closed “stop” input. The drive can be started by either causing a rising
edge (open to close) on the S1 digital input when S2 is closed, or both S1 and S2 are closed when power is applied to the drive. The drive
will then start running at the HAND frequency reference P5-02 and run for the time specified in parameter P4-18. If the drive needs to be
stopped before the P4-18 timer expires, the circuit connected to Terminal S2 can be opened, or the Stop or Off keys on the digital operator
can stop the drive. The drive can be re-started by simply causing another rising edge on Terminal S1. There will be no modified display or
messages when the drive is stopped due to the Timed Run feature. If the drive is switched into HAND or LOCAL mode, the timed run
feature will be disabled.
1. Wire-Break detection for Terminal A2 will be completely disabled during Timed Run control.
2. The pre-charge feature is disabled during Timed Run control.
3. Uses the “Hand” reference as the frequency reference. If P5-01 is set to 1, parameter P5-02 will be used as the reference. If P5-02 is set
to 0, Terminal A1 will be used as the reference.
4. The “Not Maintaining Setpoint”, and “Low Feedback” faults are disabled during Timed Run control.
5. The “Loss of Prime” fault (if enabled) will become active when the output frequency comes to within 1 Hz of the frequency reference.
6. The Timed Run Control will take priority over the “Auto Mode Fixed Speed” mode (digital input).
When this feature is enabled, the drive will run at the “Hand” frequency reference for the time specified in parameter P4-18. Timed Run
cannot be enabled when in Multiplex Mode (P1-01 > 0). (Refer to parameter P4-18.)

determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.
When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5 Hz) DC current will be injected
in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0
Default), to establish the end point of the ramp. DC injection can be used to insure the motor is at zero rpm prior to the iQpump drive
shutting off.
Figure 1.14
Figure 14. Deceleration to Stop
The actual deceleration time can be determined by the following formula.
If S-Curve characteristics are specified by the iQpump drive programming, they will add to the total time to stop.
1: Coast to stop: When the Run command is removed, the iQpump drive will turn off its output and the motor will coast (uncontrolled
deceleration). The friction of the driven equipment will eventually overcome any residual inertia of the system and the rotation will stop.
Figure 1.15
Figure 15. Coast to Stop
Important: After a stop is initiated, a subsequent Run commands input before the Minimum Baseblock Time (L2-03) has expired, will
be ignored.
2: DCInj to Stop: When the Run command is removed, the iQpump drive will Baseblock (turn off its output) for the Minimum
Baseblock Time (L2-03). Once the Minimum Baseblock Time has expired, the iQpump drive will inject DC current into the motor
windings to lock the motor shaft. The stopping time will be reduced as compared to Coast to Stop. The level of DC Injection current is set
by parameter b2-02 (50% Default). The DC Injection brake time is determined by the set value in b2-04 and the output frequency at the
time the Run command is removed.

Important: If an overcurrent (OC) fault occurs during DCInj to Stop, lengthen the Minimum Baseblock Time (L2-03) until the fault no
longer occurs.
3: Coast w / Timer: When the Run command is removed, the iQpump drive will turn off its output and the motor will coast to a stop. If
a Run command is input before time T (operation wait time) expires, the iQpump drive will not run and the Run command will need to be
cycled before operation can occur. The time T (operation wait time) is determined by the output frequency when the Run command is
removed and the active deceleration time (C1-02).

The DC Braking Group contains parameters associated with the DC injection braking feature. Parameters involving the starting
frequency, current level, braking time, and motor pre heat current level are located here.
◆ b2-01 DC Injection Braking Start Frequency
Setting Range: 0.0 ~ 10.0 Hz
Factory Default: 0.5 Hz
Parameter b2-01 sets the output frequency where the iQpump drive begins DC Injection during Ramp to stop in order to lock the rotor
of the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.
Parameter b2-01 also determines the output frequency that the iQpump drive must be at or below before a Zero Speed condition is
considered true. This affects any digital output configured as a Zero Speed signal (H2-0x = “1: Zero Speed”).

◆ b2-02 DC Injection Braking Current
Setting Range: 0 ~ 100%
Factory Default: 50%
The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the
level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to
hold the motor shaft. DC Injection current is set in percentage of the iQpump drive rated output current. iQpump drive rated output
current is stated on the iQpump drive nameplate.

The iQpump drive can be programmed to automatically DC Inject for a predetermined amount of time prior to accelerating to speed (b2-
03) and / or at the end of a Ramp to stop (b2-04). Parameter b2-03 can be used to stop a rotating motor prior to attempting acceleration
(i.e. a wind milling fan). If DC Injection braking at start or Speed Search is not enabled, attempting to drive a spinning motor may cause
nuisance tripping.
Parameter b2-04 can be used to resist any residual motion of the load after the deceleration has finished.

Parameter b2-04 also serves the function of affecting the length of time DC Injection to stop (b1-03 = “2: DC Injection to Stop”) will
occur.
◆ b2-09 Motor Pre-Heat Current
Setting Range: 0 ~ 100%
Factory Default: 0%
A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and
prevent condensation. Parameter b2-09 determines the percentage of the iQpump drive rated output current that will be used for the motor
pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions.
Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat Input (H1-0x = 60). Check with the
motor manufacturer to determine the maximum acceptable current level the motor can withstand when stopped. Be sure not to exceed the
motor manufacturers recommended level.

b3 Speed Search
The Speed Search function allows the iQpump drive to determine the speed of a motor shaft that is being driven by rotational inertia.
Speed Search will allow the iQpump drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed
without first having to bring it to a complete stop. When a momentary loss of supply power is experienced, the iQpump drive output is
turned off. This results in a coasting motor. When power returns, the iQpump drive can determine the speed of the coasting motor and
start without requiring it to be brought to minimum speed. Speed Search can be programmed to always be active by setting b3-01 or it can
be commanded by remote contact closure by setting a digital input.
There are two forms of Speed Search in the drive, the speed estimation method and the current detection method.
Important: When setting the iQpump drive for remote Speed Search input, via a contact closure, the method of Speed Search is
determined by the setting of b3-01. If b3-01 = “0: SpdsrchF Disable” then the remote input will initiate speed estimation method, and if
b3-01 = “2: SpdsrchI Disable,” then the remote input will start the current detection method.
Parameters L2-03 and L2-04 also affect the current detection method of Speed Search operation.
◆ b3-01 Speed Search Selection
This parameter is effective only when the iQpump drive is given a new Run command.
Setting Description
0 SpdsrchF Disable
1SpdsrchF Enable
2 SpdsrchI Disable (factory default)
3SpdsrchI Enable
Speed Estimation: Method (b3-01 = 0 or 1) The speed estimation method will calculate the speed using measurements of residual
motor fields. The speed estimation version is bi-directional and will determine both the motor speed and direction. To enable speed
estimation Speed Search at start, set b3-01 = “1: SpdsrchF Enable”.
Important: If the speed estimation method of Speed Search is to be used, then Auto-tuning must be performed prior to using Speed
Search. If the length of cable between the iQpump drive and motor is ever changed after Auto-tuning then Auto-tuning should be
performed again
Important: The speed estimation mode cannot be used when there are multiple motors operated by one iQpump drive or the motor is two
or more frames smaller than the standard size motor per the iQpump drive capacity.

Current Detection Method (b3-01 = 2 or 3): The current detection method starts searching from a predetermined frequency while
monitoring the iQpump drive output current to determine when the rotor speed and the iQpump drive output speed (frequency) match.
The current detection version is not bi-directional. To enable current detection Speed Search at start set b3-01 = “3: SpdscrhI enable” and
program any digital input equal to Speed Search 1 (H1-0x = 61) or Speed Search 2 (H1-0x = 62). Speed Search 1 will start searching from
the max. frequency (E1-04) and ramp down to meet the rotor speed. Speed Search 2 will start searching from the set frequency and ramp
down to meet the rotor speed.
Important: If a UV1 fault occurs when current detection Speed Search is attempted, increase the setting of L2-04.
Important: If an OC fault occurs when Speed Search is attempted after power loss recovery, increase the setting of L2-03.

◆ b3-02 Speed Search Deactivation Current
Setting Range: 0 ~ 200% of the iQpump drive rated output current
Factory Default: 120% of the iQpump drive rated output current
When using the current detection method of Speed Search, parameter b3-02 sets the current level that will determine when the search is
complete and the rotor and output speeds match. When the output frequency is higher than the actual rotor speed, the slip causes the
current to be high. As the output frequency is lowered, the closer it comes to the rotor speed, the lower the current draw will be. When the
output current drops below the level as set in b3-02 (100% = iQpump drive Rated Current) the output frequency stops decreasing and
normal operation resumes.
◆ b3-03 Speed Search Deceleration Time
Setting Range: 0.1 ~ 10.0 s
Factory Default: 2.0 s
Parameter b3-03 sets the deceleration ramp used by the current detection method of Speed Search when searching for the motor’s rotor
speed. Even if Speed Search 2 is selected, for Speed Search at start, the time entered into b3-03 will be the time to decelerate from
maximum frequency (E1-04) to minimum frequency (E1-09).
YASK AWA TM.iQp.07 iQpump Controller Programming Manual 29
◆ b3-05 Speed Search Delay Time
Setting Range: 0.0 ~ 20.0 s
Factory Default: 0.2 s
In cases where an output contactor is used between the iQpump drive and the motor, extra waiting time is provided after power returns
and before Speed Search is performed. This extra time allows for the contactor to operate. When Speed Search at start is used, b3-05 will
serve as the lower limit of the Minimum Baseblock Time (L2-03).
◆ b3-14 Bi-Directional Speed Search Selection
Setting Description
0Disabled
1 Enabled (factory default)
The b3-14 parameter can be used to turn off the bi-directional capabilities of the Speed Estimation form of Speed Search. By turning off
the bi-directional capability, the speed search will only try to match the speed in the last known direction.
