MOTOR 2 TEMP
ABB · ACS800
What does 4313 mean?
The measured temperature from motor sensor 2, connected to the ABB ACS800 drive, has exceeded the alarm limit set by parameter 35.05. This fault (3.16 AW 4 bit 2) indicates a detected overheating condition in the motor, requiring immediate attention to prevent winding damage or component failure.
Common Causes
- Motor temperature exceeding the alarm limit defined by parameter 35.05 (MOTOR 2 TEMP ALARM).
- Incorrect setting of parameter 35.05 (MOTOR 2 TEMP ALARM), potentially set too low for normal operating conditions.
- Incorrect number of temperature sensors configured in the drive compared to the actual sensors installed.
- Motor overload, inadequate motor cooling, or high ambient temperature contributing to excessive heat.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Allow the motor to cool down. Identify and address the source of excessive motor heat, such as motor overload, insufficient cooling, or high ambient temperature.
- 2
Verify the value set in parameter 35.05 (MOTOR 2 TEMP ALARM) is appropriate for the motor's thermal characteristics and the application.
- 3
Ensure that the parameter reflecting the actual number of motor temperature sensors corresponds to the physical installation in the motor.
- 4
Inspect the motor cooling fan for proper operation, clean cooling surfaces, and ensure clear airflow around the motor body.
- 5
Check the motor's load and operating conditions to ensure they are within the motor's continuous rating, especially for long operating cycles.
