n-Monitoring

What does 08 mean?

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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

2. 4

   Verify the encoder voltage supply is stable and within specifications.

3. 5

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

4. 6

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