contactor are available, it is possible to bring the DC link voltage in
this drive converter status into a no-voltage condition!
♦ The message is available as long as an OFF2 command is present
via control word bit 1 or an OFF3 command is available via control

Output at the terminal strip with L signal.
Alarm, "Setpoint-actual value deviation" (A034)
♦ A deviation of the actual value compared to the comparison setpoint
has occurred which is larger than P792 (set/act dev) and lasts
longer than P794 (set/act dev. time). (See also function diagram

♦ The bit is again set as H signal, if the deviation is less than
parameter value P792.
