Over current

What does ALARM 13 mean?

The inverter peak current limit (approximately 200% of rated current) has been exceeded. The warning lasts about 1.5 seconds before the frequency converter trips and issues an alarm. This is often caused by shock loading, rapid acceleration of high-inertia loads, or can occur after kinetic back-up. An overcurrent condition can rapidly damage the inverter's power components.

Complete Troubleshooting Guide

1. 1

   Remove power and physically check if the motor shaft can be turned freely.

2. 2

   Verify that the motor size is appropriate and matches the frequency converter's rating.

3. 3

   Confirm that the motor data in parameters 1-20 to 1-25 is correctly entered.
