6. NORMAL GAIN ADJUSTMENT
6 - 19
3) [Pr. PB08 Position loop gain]
This parameter determines the response level to a disturbance to the position control loop.
Increasing the value increases the response level to the disturbance, but a too high value will
increase vibration of the mechanical system.

4) [Pr. PB07 Model loop gain]
This parameter determines the response level to a position command. Increasing the value
improves trackability to a position command, but a too high value will make overshoot liable to
occur at settling.
