62

Output frequency at maximum limit

Danfoss · VLT HVAC Drive High Power

What does 62 mean?

The frequency converter's output frequency has reached or exceeded the maximum value set in parameter 4-19 (Max Output Frequency). This typically occurs when the drive is commanded to run faster than its configured limit, potentially indicating an over-speed condition or an incorrectly set limit for the application.

Complete Troubleshooting Guide

  1. 1

    Review parameter 4-19 (Max Output Frequency) and adjust it if the application requires a higher maximum frequency, ensuring the motor and mechanical system can safely handle it.

  2. 2

    Check the commanded reference signal to ensure it is not requesting an excessively high frequency.

  3. 3

    Verify the motor's actual operating speed to determine if it is truly over-speeding.
