4.2.10 Fault
This device status will be active as soon as a monitoring mode responds the error response "Fault"
has been parameterised for.
• The motor has no torque (is coasting) due to the inhibit of the inverter.
• The error must explicitly be reset ("acknowledged") in order to exit the device status, e.g. by the
device command " Reset error " or via the control bit "ResetFault" in the control word
wCanControl or wMCIControl.

Note!
If an undervoltage in the DC bus of the drive controller occurs (error message "LU"), the
device changes to the " Trouble " status.
An additional error of higher priority leads the device into the " Fault " status.
According to the Device state machine , the device changes to the " ReadyToSwitchOn "
status after acknowledging the error although the undervoltage is still available!
If the "Inhibit at fault" auto-start option has been activated in
C00142 , explicit
deactivation of the controller inhibit is required before the status can be abandoned.
