The following filters are activated using p1656 and p1657:
● Enter the natural frequency for manipulated variable filters 1, 2 (PT2 low-pass) in the
velocity controller.
● Enter the damping for manipulated variable filters 1, 2 (PT2 low-pass) in the velocity
controller.
● Enter the blocking frequency for control output filters 1, 2 (bandstop) in the velocity
controller.
● Enter the -3 dB bandwidth for manipulated variable filters 1, 2 (bandstop) in the velocity
controller.
● Enter the numerator bandwidth for control output filters 1, 2 (damped bandstop) in the
velocity controller. Entering a value of 0 initializes the filter as an unattenuated bandstop
filter.
