62

Output frequency at maximum limit

Danfoss · VLT HVAC-FC 102 Frequency Converter

What does 62 mean?

The output frequency has reached the maximum value set in parameter 4-19 (Max Output Frequency). This indicates the drive is attempting to run the motor faster than its configured limit, potentially due to incorrect parameter settings or application requirements exceeding the drive's setup. The warning will clear when the output frequency drops below the maximum limit.

Complete Troubleshooting Guide

  1. 1

    Examine the application requirements to understand why the motor needs to run at or above the current maximum output frequency setting.

  2. 2

    If the application genuinely requires a higher speed, cautiously increase the value in parameter 4-19 (Max Output Frequency).

  3. 3

    Before increasing the limit, confirm that the motor, mechanical system, and driven equipment can safely operate at higher speeds without damage.
