Power Off Required for Hardware Reconfiguration

What does FF39 mean?

The inverter type (e.g., sr0025_3) has been changed, typically at the factory or during drive implementation, and a power cycle is required to validate this change. This alarm prompts the user to switch off the control board power to finalize the hardware reconfiguration and allow the drive to operate with the new settings.

Complete Troubleshooting Guide

1. 1

   Switch the control board power off completely and then back on to validate the inverter type change and clear the alarm.
