BENTLY 125744-02 Voltage input module

The overdamped (undershooting) velocity loop does not respond to velocity changes (disturbances) quickly. It has soft, smooth motion. It requires extra time to settle. Increasing KVI and/or KVP will bring the system closer to critically damped. Remember, when increasing KVP, the ARFx filters may need to be increased proportionally. In this waveform, the current feedback is extremely low and the ripple shown is acceptable (normal) because it is much less than ± 5% of peak rated current.

Underdamped

The underdamped (overshooting) velocity loop is an unstable waveform. It has wasted oscillatory motion. It requires extra time to settle. Decreasing KVI and/or increasing KVP will bring the system closer to critically damped. Remember, when increasing KVP, the ARFx filters may need to be increased proportionally. In this waveform, the oscillating current is a result of the ARFx filters being set too low.

Critically damped

The critically damped velocity loop follows the command without overshoot or undershoot. It has the shortest settling time and no wasted motion. Get as close to this waveform as possible.
