Actions
Extend the deceleration time.
Decrease the setting value.
Reduce the load.
Increase the capacity of Inverter and
Motor.
2
too larger?
Change to flying start mode.
Redesign the system so that the motor is not
driven by external force.
Use a brake resistor with a larger capacity.
Extened the deceleration time.
2
(so that GD of the load is met)
Reduce the braking frequency.
Increase the brake resistor capacity.
Checking feedback signal cable and connected
securely.
Set gain frequency properly.
