MOTOR TEMP

What does 4310 mean?

The ABB ACS800 drive has detected or estimated that the motor temperature is too high. This condition (3.08 AW 1 bit 3) can be caused by excessive load, an undersized motor, inadequate cooling, or incorrect drive configuration, potentially leading to motor winding damage or premature failure. It is controlled by programmable Fault Function parameters 30.04 to 30.09.

• Excessive mechanical load continuously applied to the motor.
• The motor is undersized for the current application requirements.
• Inadequate motor cooling due to a blocked fan, dirty cooling surfaces, or insufficient ambient airflow.
• Incorrect motor ratings or start-up data configured in the drive (parameter group 99 START-UP DATA).
• Incorrect settings for motor temperature Fault Function parameters (30.04…30.09) in the drive.

Click steps to track your progress.

1. 1

   Check the mechanical load on the motor and compare it to the motor's rated capacity; reduce load if it is consistently exceeding the motor's capabilities.

2. 2

   Inspect the motor's cooling fan and cooling surfaces (fins, vents) for blockages or dirt; clean thoroughly to ensure optimal heat dissipation.

3. 3

   Verify all motor ratings (power, current, speed, frequency, voltage) entered in the ABB ACS800 drive's start-up data (parameter group 99 START-UP DATA) precisely match the motor nameplate.

4. 4

   Review and adjust the motor temperature Fault Function parameters (30.04…30.09) to ensure they are appropriate for the motor's thermal characteristics and the application.

5. 5

   Monitor actual motor temperature (if sensors are installed) and compare it to the alarm and trip limits to understand the heating profile.
