Measurement circuit temperature
ABB · ACS580 General Purpose Drive
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.
Complete Troubleshooting Guide
- 1
Note the auxiliary code (format XXXY YYZZ) to identify the specific location of the temperature measurement problem (e.g., U-phase IGBT, power supply board).
- 2
Perform a visual inspection of the identified component and its immediate vicinity for any signs of damage, loose connections, or environmental factors affecting temperature sensing.
- 3
Ensure proper ventilation and cooling within the drive and its enclosure.
- 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.
