Upper Limit of
Integral Control
Range: 00 to 100% Default: 100%
50.40
PID Output Delay
Filter Time
Range: 0.0 to 2.5 seconds Default: 0.0 sec
Units: 0.1 seconds

4 – 20 mA Input Loss
Detection Time
Range: 0.1 to 3600 seconds
00 Disabled
Default: 60 sec Units: 0.1 second
If the 4 – 20 mA input falls below 4 mA, the drive will consider
this a loss of input speed command. Upon loss of 4 – 20 mA,
the AC drive will begin to record time. If the time set in 50.41
is reached, the AC drive will follow the operation selection in
50.42.
50.42
4 – 20 mA Input Loss
Operation
Range: Default: 00
00 Warn and Stop operation
01 Warn and continue to run at last known speed command
This parameter selects the operation of the AC drive after a
loss of 4 – 20 mA input is detected and the time set in 50.41 is
reached. This parameter is disabled if 30.04 is set to 0.0 mA.
50.43
PID Setpoint Range: Default: 00 Hz
0.1 to 400.0 Hz
00 Hz Disabled
Units: 0.1 Hz
This parameter sets the frequency target value for the PID
function.
