If a nonstandard motor is to be used, the initial value for this parameter
must be determined through extensive motor testing. For assistance call
Allen-Bradley Commercial Engineering at (440) 646-5000.
Generally, if set too high, the axis is underdampened and oscillation
results. If set too low, the axis is overdampened and requires too much
time to reach speed.

Notes
This parameter must be set independently for each servo.
For assistance on determining the optimal velocity proportional gain
amount refer to the tuning procedure in appendix A of this manual.
