Overtemperature in brake

¿Qué significa 89 ?

The integrated motor brake has exceeded its safe operating temperature limit. This is often caused by frequent braking cycles, continuous brake slipping, or high ambient temperatures affecting the brake mechanism.

• Frequent braking cycles leading to excessive heat generation
• Continuous slipping of the brake during operation
• High ambient temperature affecting the motor brake
• Damage or malfunction of the brake coil

1. 1

   Verify drive parameters related to brake control (e.g., release/engage times, holding voltage/current) against application requirements and manufacturer specifications.

2. 2

   Inspect the mechanical condition of the motor brake, checking for signs of wear, correct air gap, and any obstructions causing drag or slipping.

3. 3

   Measure the actual brake control voltage/current at the motor terminal block to confirm it matches the drive output and specified brake coil voltage.

4. 4

   Measure the ambient temperature around the motor and brake assembly, and inspect the motor cooling fan for proper operation and clear airflow.
