n-Monitoring

Hva betyr 08 ?

Immediate switch-off because the speed controller or current controller is operating at its setting limit. This can be due to mechanical overload, a phase failure in the power supply or motor, an incorrectly connected encoder, or exceeding the maximum speed (nmax) during torque control.

• Motor speed (n) is not within the expected monitored range during operation.
• Discrepancy between commanded speed and actual motor speed.
• Faulty speed feedback mechanism or motor performance deviation.

1. 1

   Reduce the mechanical load on the motor.

2. 2

   Increase the deceleration time setting (P501 or P503) to allow for longer deceleration.

3. 3

   Check the encoder connection; if necessary, swap A/A and B/B signal pairs to correct direction.

4. 4

   Verify the encoder voltage supply is stable and within specifications.

5. 5

   Check the current limitation settings (e.g., P303 for maximum current).

6. 6

   Extend acceleration/deceleration ramps if current limits are being hit.
