Over-Current at deceleration

When the frequency inverter decelerates, output current exceeds over-current

Check whether the motor is and its lines are short circuit, grounded or too long;
Conduct parameter identification delay the deceleration time;
Delay the deceleration time;
Check whether the input voltage is relativily low;
Check whether the input voltage is relatively low; Check whether the load has mutation;
Install additional brake unit and brake resistance;
