4.4.3 Function for Changing the Proportional Gain in the Stop State
(1) Overview
The velocity gain or load inertia ratio is generally increased if a large
load inertia is applied to a motor, or to improve the response. An
excessively large velocity gain may cause the motor to generate a
high-frequency vibration when it stops. This vibration is caused by
excessive proportional gain of the velocity loop (PK2V) when the
motor is released within the backlash of the machine in the stop state.
This function decreases the velocity loop proportional gain (PK2V) in
the stop state only. The function can suppress the vibration in the stop
state and also enables the setting of a high velocity gain.
