Comment:
In the event of overtemperature, l
2
t monitoring or
braking power monitoring, the fault will be acknowl-
edged automatically after a cooling down phase.
Manual acknowledgment is not possible.
Troubleshoot the fault using
the output terminals and
acknowledge it using the
input terminal.
DC LINK - Off The DC link voltage is not available, the electronics
power supply is missing or is outside the permissible
tolerance range.
The component is not active.
