Fan cooling

What does 32 mean?

The frequency converter's cooling fan failed to start when an ON command was issued. This is a critical issue as the fan is essential for dissipating internal heat from power components. Its failure will lead to rapid overheating and potential damage to the drive if operation continues.

Complete Troubleshooting Guide

1. 1

   Listen for the cooling fan operation immediately after an ON command; if no sound, the fan is likely stuck or has failed.

2. 2

   With the drive powered off and locked out, visually inspect the fan for any obstructions, debris, or visible damage.

3. 3

   If the fan is confirmed not working, contact your Vacon distributor for service, as it may require replacement.
