4.6 Basic iQpump Setup and Application Preset Parameters
Setting 0: Operator (HOA keypad)
This setting requires entering the Run command via the HOA keypad AUTO key and also illuminates the HAND indicator
on the digital operator.
Setting 1: Control Circuit Terminal
This setting requires entering the Run command via the digital input terminals using one of following sequences:
• 2-Wire sequence 1:
Two inputs (FWD/Stop-REV/Stop). Set A1-03 to 2220 to initialize the drive and preset terminals S1 and S2 to these
functions. This is the default setting of the drive.
• 2-Wire sequence 2:
Two inputs (Start/Stop-FWD/REV).
• 3-Wire sequence:
Three inputs (Start-Stop-FWD/REV). Set A1-03 to 3330 to initialize the drive and preset terminals S1, S2, and S5 to these
functions. Refer to Setting 0: 3-Wire Sequence on page
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the Run command via serial communications by connecting the RS-485/422 serial
communication cable to control terminals R+, R-, S+, and S- on the removable terminal block.
Setting 3: Option Card
This setting requires entering the Run command via the communication option board by plugging a communication option
board into the CN5-A port on the control PCB. Refer to the option board manual for instructions on integrating the drive into
the communication system.
Note: If b1-02 is set to 3, but an option board is not installed in CN5-A, an oPE05 operator programming error will be displayed on the digital
operator and the drive will not run.
n b1-03: Stopping Method Selection
Selects how the drive stops the motor when the Run command is removed or when a Stop command is entered.
No.
b1-03
Setting 0: Ramp to Stop
When the Run command is removed, the drive will decelerate the motor to stop. The deceleration rate is determined by the
active deceleration time. The default deceleration time is set to parameter C1-02.
When the output frequency falls below the level set in parameter b2-01, the drive will start DC injection, Zero Speed Control,
or Short Circuit Braking.
Setting 1: Coast to Stop
When the Run command is removed, the drive will shut off its output and the motor will coast (uncontrolled deceleration) to
stop. The stopping time is determined by the inertia and the friction in the driven system.
Note: After a stop is initiated, any subsequent Run command entered will be ignored until the minimum baseblock time (L2-03) has expired. Do
not enter Run command until it has come to a complete stop. Use DC Injection at Start
Circuit Braking on page
