Cause : INT CONFIG comes when number of inverter modules is not equal to original number of inverters. This disrupts the proper operation of the drive and can lead to the drive shutting down to protect itself.

The code 5410 in your ABB ACS800 drive indicates a communication issue between the control board (APBU) and the inverter modules.

1. Check status of inverters. See signal 04.01 FAULTED INT INFO.
2. Check fiber optic cables between APBU and inverter modules.
3. If Reduced Run function is used, remove faulted inverter module from main circuit and write number of remaining inverter modules into parameter 95.03 INT CONFIG USER. Reset drive.
