Measurement circuit temperature

What does A5EA mean?

A problem has been detected with the internal temperature measurement circuit of the drive. This means the drive may be unable to accurately monitor the temperatures of critical components (e.g., IGBTs, power supply board), which could lead to undetected overheating and damage if left unresolved. The auxiliary code provides specific location details of the issue.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Ensure proper ventilation and cooling within the drive and its enclosure.

2. 4

   If the fault persists and no external cause is found, contact your local ABB representative as it may indicate an internal sensor or board failure.
