Power unit: Overtemperature thermal model

What does A05006 mean?

This alarm indicates that the calculated temperature difference between the power chip and the heat sink has exceeded the permissible limit, primarily for blocksize power units. It signifies a potential thermal imbalance or overload condition that, if not self-corrected, can lead to fault F30024. The drive initiates an appropriate overload response based on p0290.

Complete Troubleshooting Guide

1. 1

   No immediate manual intervention is typically necessary as the alarm should clear automatically when the temperature difference falls below the limit.

2. 2

   Monitor the drive; if the alarm persists or temperature continues to rise, investigate potential causes of overheating to prevent fault F30024.
