Feedback Velocity (Fbvel); Lowpass Filter (Lopass); Notch Filter (Notch) - Parker ACR7000 Series Programmer's Manual

APPENDIX C: SERVO PID TUNING

Feedback Velocity (FBVEL)

Sets the velocity feedback gain to amplify the rate of change of feedback. Only for analog feedback systems or
dual-feedback loop systems (motor feedback for velocity and load-mounted encoder for position). For standard
servo drives, this should be left at 0.0.

Lowpass Filter (LOPASS)

This command initializes the output filter as a lowpass filter, reducing high-frequency noise that may occur in a
system. Setting the cutoff frequency to zero turns off the lowpass filter.

Notch Filter (NOTCH)

This command sets up the first half of the output filter to act as a notch filter, reducing mechanical resonance that
may occur in a system. Setting the center frequency to zero turns off the notch filter.
