Over-current at acceleration

When the frequency inverter accelerates, output current exceeds over-current.

Check whether the motor is and its lines are short circuit, grounded or too long;
Check whether the input voltage is relatively low;
Delay the acceleration time;
Conduct parameter identification or improve low frequency torque compensation or adjust V/F Curve;
Check whether the load has mutation;
Check whether it is to select speed tracking or start after the motor stops stably;
Check whether the rated power of the motor or frequency inverter is large enough;
