PID DERIV FILTER
Defines the filter time constant for the derivative part of the process PID
controller. Increasing the filter time smooths the derivative and reduces
noise.
1.0 s
0.0
…10.0 s
Filter time constant. If parameter value is set to zero, the derivative filter is
disabled.
4005
ERROR VALUE INV
Selects the relationship between the feedback signal and drive speed (drive
output frequency).
0 = NO
0 = NO
Normal: A decrease in feedback signal increases drive speed (drive output
frequency). Error = Ref - Fbk
1 = YES
Inverted: A decrease in feedback signal decreases drive speed (drive output
frequency). Error = Fbk - Ref
