Controller DC-Link voltage out of range (< 40 or > 54 V DC)
If the voltage is out of range the system starts to reduce the speed and a warning is generated. When
reaching 0 rpm and the voltage is still out of range the system is disabled and an error is generated. In
case the voltage is again within the range during speed reduction the system switches to normal
operation and no Error is generated.
