STEP
Task Parameter Name Description/Menu Access Default Value
12.1
NOTICE:
Adjusting this
parameter may cause PID
control loop instability if
misadjusted.
b5-03 Integral Time Setting
(I)
Sets the integral time for the PID controller.
Decrease integral time to make the drive
more responsive.
Programming
3.0 seconds
12.2
NOTE
: Disable parameter
b5-12 if a transducer is not
installed.
b5-12 Feedback Loss
4 to 20 mA
Detection Selection
Performs a 4 to 20 mA wire break detection
on the analog input that is programmed for
PID feedback. Terminal TB1-1 A2 (typical)
0: Disabled, continue running, no message
is displayed.
1: Alarm, display warning on the HOA
keypad when the feedback device fails or
is disconnected.
2: Fault, stop the pump system when the
feedback fails or is disconnected.
3: Run at the setting value of parameter
b5-13.
2 (Fault)
12.3 Adjust depending on
system performance.
C1-01 Acceleration Time 1 Sets the time to accelerate the pump motor
from zero to maximum speed.
Programming
NOTE: The factory default with Thrust Mode
enabled is 12.0 seconds, 20.0 seconds
when disabled.
20.0 seconds
See Note
C1-02 Deceleration Time 1 Sets the time to decelerate the pump motor
from maximum speed to zero.
Programming
Note: The factory default with Thrust Mode
enabled is 5.0 seconds, 10.0 seconds when
disabled.
10.0 seconds
See Note
12.5 Refer to L5 parameter
group (See U1000 iQpump
Drive User Manual No.
TOEPYAIUPW01).
The number of restart attempts
is set by L5-01.
Configurable drive System
Protection Faults for Auto-
restart:
- Low Level Feedback
- High Level Feedback
- Transducer Loss
- Not Maintaining Setpoint
- Loss of Prime
- Pump Over Cycle.
L5-01 Number of Restart
Attempts
Sets the number of times the drive may
attempt to restart after these faults occur:
– Aov - Power Supply Overvoltage
– GF - Ground Fault
– LF - Output Phase Loss
– LSo - LSo Fault
– oC - Overcurrent
– oH1 - Drive Overheat
– oL1 - Motor Overload
– oL3 - Overtorque 1
– oL4 - Overtorque 2
– ov - DC Bus Overvoltage
– STo - Pull-Out Detection
