Mechanical brake low

Was bedeutet 63 ?

The actual motor current failed to exceed the configured release brake current within the specified start delay time window. This indicates an issue with the mechanical brake's release mechanism, potentially due to a stuck brake, insufficient current to release it, or incorrect timing settings, preventing the motor from starting.

• The mechanical brake coil is faulty (e.g., open circuit, short circuit) or its power supply is insufficient.
• Insufficient voltage or current being supplied from the drive's brake control terminals to the brake.
• Mechanical issue with the brake pads, springs, or release mechanism (e.g., worn, binding, seized).
• Incorrect brake release current parameter (e.g., P1-62) or start delay time (e.g., P1-60) settings.
• Drive's motor current sensor is faulty, leading to an incorrect measurement of motor current during release.
• The load is too heavy for the motor to generate sufficient current to overcome the brake within the delay time.

1. 1

   1. Verify the supply voltage to the mechanical brake coil using a multimeter at the brake's terminals.

2. 2

   2. Measure the resistance of the brake coil (e.g., at brake terminals) to check for open or short circuits.

3. 3

   3. Adjust Parameter P1-60 (Brake Open Delay Time) to allow more time for the brake to fully release.

4. 4

   4. Adjust Parameter P1-62 (Brake Release Current) to a higher value if the motor requires more current to overcome initial brake drag.

5. 5

   5. Manually inspect the mechanical brake for worn pads, rust, physical obstructions, or signs of overheating preventing disengagement.

6. 6

   6. Confirm drive's output current during brake release (e.g., P16-04) is reaching or exceeding the set brake release current (P1-62).
