Speed monitoring

What does 08 mean?

Speed monitoring has been triggered, indicating that the load on the drive is too high, causing the motor speed to deviate beyond acceptable limits. This protective function prevents the motor from operating outside its designed speed range under excessive load.

• Actual motor speed deviates significantly from setpoint.
• Encoder feedback signal loss or corruption.
• Incorrect speed control loop tuning (e.g., P0338, P0340).
• Mechanical load changes exceeding drive capability.
• Parameter P0260 (speed monitoring) threshold too sensitive.

Click steps to track your progress.

1. 1

   Reduce the mechanical load on the drive.

2. 2

   Increase the n-monitoring delay time setting in the inverter parameters.

3. 3

   Reset the fault by switching off the DC 24 V supply voltage.
