Increase the gain by turning clockwise

(cw) using 

"KV potentiometer"

 until

achieving a situation as shown on the left.

Insufficient proportional gain.

To reduce the overshoot adjust

clockwise (cw) using 

"Der

potentiometer"

 until achieving a situation

as shown on the left.

Caution

: Do not set KV too high :  it can

cause unnecessary motor heating

caused from ocsillating currents in the

motor.

It's possible to increase the velocity loop derivative constant

by inserting a capacitor CDER on the personalization

adjustment.
