OH4 Heatsink temperature > C0122

What does x054 mean?

The heatsink temperature has exceeded the specific threshold value set in parameter C0122. This is an advance warning for heatsink overheating, which can be caused by high ambient temperatures (Tu > +40°C or +50°C), a dirty heatsink, or an incorrect mounting position. This monitoring can be switched off via C0582.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify and, if necessary, change the drive's mounting position to ensure optimal airflow and ventilation.

2. 4

   If the value specified in C0122 is too low for the application, enter a higher value for the heatsink temperature threshold.

3. 5

   If monitoring needs to be disabled, set parameter C0582 = 3.
