Cause : Vdc-max controller de-activated. Vdc max controller has been de-activated, since controller is not capable of keeping DC-link voltage (r0026) within limits (P2172).

- Occurs if main supply voltage (P0210) is permanently too high

- Occurs if motor is driven by an active load, causing motor to go into regenerative mode

- Occurs at very high load inertias, when ramping down

Diagnose & Remedy

Check the following:
1. Input voltage (P0210) must lie within range
2. Load must be match
