Device changed (same type)

What does 37 mean?

An option board or control unit has been replaced with another of the exact same type or power rating. While the hardware is compatible, the system registers a component change. A reset is typically required to recognize the new component and ensure existing parameter settings are correctly applied.

Complete Troubleshooting Guide

1. 1

   Perform a reset on the frequency converter to allow the drive to recognize the newly installed component.

2. 2

   After the reset, verify that the drive operates correctly and that all previously configured parameter settings are retained and functional.
