MOTOR 1 TEMP

Was bedeutet 4312 ?

The measured temperature from motor sensor 1, connected to the ABB ACS800 drive, has exceeded the alarm limit set by parameter 35.02. This fault (3.16 AW 4 bit 1) indicates a detected overheating condition in the motor, requiring immediate attention to prevent winding damage or component failure.

• Motor temperature exceeding the alarm limit defined by parameter 35.02 (MOTOR 1 TEMP ALARM).
• Incorrect setting of parameter 35.02 (MOTOR 1 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.

1. 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. 2

   Verify the value set in parameter 35.02 (MOTOR 1 TEMP ALARM) is appropriate for the motor's thermal characteristics and the application.

3. 3

   Ensure that the parameter reflecting the actual number of motor temperature sensors corresponds to the physical installation in the motor.

4. 4

   Inspect the motor cooling fan for proper operation, clean cooling surfaces, and ensure clear airflow around the motor body.

5. 5

   Check the motor's load and operating conditions to ensure they are within the motor's continuous rating, especially for long operating cycles.
