Power unit: Air intake overtemperature

What does A05002 mean?

The alarm threshold for the air intake temperature of the power unit has been reached, typically at 42 °C. This indicates insufficient cooling or high ambient temperatures affecting the drive's internal environment. If the air intake temperature increases by an additional 13 K, it will lead to fault F30035, likely resulting in a drive shutdown.

Complete Troubleshooting Guide

1. 1

   Check if the ambient temperature is within the specified operating limits for the drive unit.

2. 2

   Inspect the cooling fan for failure or reduced performance, and verify its direction of rotation is correct.
