Cause : Vdc_max controller de-activated comes when the main supply voltage (P0210) is permanently too high or motor is driven by an active load, causing motor to go into regenerative mode.

Check the following:

• Input voltage must lie within range.
• Load must be match.
• In certain cases apply braking resistor.
