When TRUE, the integral term does not operate.
Range: -500.00 to 500.00 %
The integral term will be preset to this value when the drive starts.
The speed demand is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
The speed feedback is filtered to reduce ripple, such as that caused by low line count encoders. The filter is first order with
time constant equal to the value of this parameter.
Range: -300.00 to 300.00 %
When the drive is operating in speed control mode, the value of this parameter is added on to the torque demand produced by
the speed loop PI. When the drive is operating in torque control mode (i.e. “torque demand isolate is TRUE) the speed loop
PI does not operate, and the torque demand becomes the sum of this parameter plus the DIRECT INPUT (if selected).
If the speed demand is less than the adaptive threshold, the speed loop proportional gain is the adaptive p-gain.
PREF: 78.09 Default: 20.00 Range: 0.00 to 300.00
Proportional gain used if speed demand < adaptive threshold.
