Low Pass Filter Bandwidth

The Low Pass Filter Bandwidth parameter sets the bandwidth frequency of the
low pass filter that is applied to the velocity command input for the velocity
regulator. It can be set in the range 0–10,000 Hz. This filter is disabled when
the setting is 0. This filter may be useful in reducing noise on the analog
velocity command. It will also soften the edge of a step command input to the
velocity regulator. This filter setting affects the velocity loop bandwidth.

Position Regulator Settings

The position regulator includes the following parameters available for
adjustment by the user:
•
Kp
•
Kff
