Power Card Temperature Overload

What does 2 mean?

This fault signifies that the temperature of the drive's power card, which contains critical components like IGBTs, has exceeded its safe operating limit. Overheating can lead to premature component failure, reduced drive lifespan, and unexpected shutdowns to prevent damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Confirm the motor load is not excessive, causing the drive to work harder and generate more heat.

2. 4

   Ensure the drive enclosure provides proper ventilation and that internal components are not obstructed.

3. 5

   Monitor the heatsink temperature via drive parameters (e.g., 16-34) to confirm cooling effectiveness.
