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 "
" or via the control bit "ResetFault" in the control word
wCanControl
or
wMCIControl
.
