Over-voltage at acceleration

When the frequency inverter runs at constant speed, DC voltage of the main circuit exceeds this set value. The detected over-voltage value is the same as above

Check whether the input voltage is too high;
Check whether the bus voltage display is normal;
Delay the deceleration time;
Check whether the motor is dragged to run by external force in the process of deceleration;
Install additional brake unit and brake resistance;
