Cause : Belt Failure Detected - Load conditions on motor indicate belt failure or mechanical fault.

Diagnosis & Remedy

Check the following:

1. No breakage, seizure or obstruction of drive train.

2. If using an external speed sensor, check for correct function. Check parameters:
- P0409 (pulse per min at rated speed).
- P2191 (Belt failure speed tolerance).
- P2192 (delay time for permitted deviation)

3. If using the torque envelope, check parameters:
- P2182 (threshold frequency f1)
- P2183 (threshold frequency f2)
- P2184 (threshold frequency f3)
- P2185 (upper torque threshold 1)
- P2186 (lower torque threshold 1)
- P2187 (upper torque threshold 2)
- P2188 (lower torque threshold 2)
- P2189 (upper torque threshold 3)
- P2190 (lower torque threshold 3)
- P2192 (delay time for permitted deviation)

4. Apply lubrication if required.
