Host Command Reference
KV - Velocity Feedback Constant
Compatibility: Servo drives only
Affects:
Servo tuning and performance
Sets or requests the servo control velocity feedback gain term. Gain value is relative: “0” meaning no gain,
“32767” meaning full gain. KV is part of the Damping servo parameters in Quick Tuner. It aids the KD command
in damping system oscillation. This term helps to control larger inertial loads.
NOTE: The Velocity Feedback (KV) and Velocity Feedforward (KF) constants are typically set to similar values.
The Feedforward value may at times be set larger depending on the frictional content of the motor load.
NOTE: It is recommended to use the Quick Tuner software for tuning and configuring your servo system.
