Motor overtemperature shutdown
Bosch Rexroth · IndraDrive C Drive Controllers
What does F2019 mean?
The motor has reached a critical temperature threshold, triggering a safety shutdown to prevent damage to its windings or insulation. This is a severe thermal event.
Common Causes
- Motor running at excessive load for extended periods.
- Inadequate motor cooling due to blocked vents, fan failure, or high ambient temperature.
- Incorrect motor thermal model parameters in the drive.
- Faulty motor temperature sensor or wiring leading to false readings.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Allow the motor to cool down completely before attempting to reset the fault. Do not attempt to operate the motor immediately.
- 2
Check the mechanical load on the motor and ensure it is within specified limits for continuous operation.
- 3
Verify the motor's cooling system (fans, fins) is clean and functioning correctly. Ensure adequate airflow around the motor.
- 4
Inspect motor cabling and temperature sensor wiring for damage or loose terminals. Measure the resistance of the motor's temperature sensor (e.g., PTC/KTY/PT1000) and compare to expected values.
