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) when the inverter is inhibited.
• 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.

4.2.11 SystemFault
This device state is not used since the inverter lacks the activating event.
This device status becomes active if a system fault occurs.
• The device status can only be abandoned by
•mains switching or
• a system restart.

Note!
If an undervoltage in the DC bus of the inverter 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.
