3. Select "Next step >".
The power data of the infeed is configured here:
– When the checkbox is selected, the line/DC link identification is activated once the infeed
– Enter the device connection voltage: This is the basis for monitoring the line voltage
– The actual line frequency for the infeed is determined automatically.
– In parameters p0284, p0285, set a threshold above which an alarm is triggered (default

pulse enable has been activated (p3410). The infeed then switches to operational mode.
Note
DC link identification
If the line supply environment changes or the components on the DC link change (e.g.
after setting up the equipment at the customer site or after expanding the drive group),
the checkbox must be set again: Hence the "Power data" softkey in the overview in order
to restart the line/DC link circuit identification.
If p3410 = 5 is saved in the commissioning archive, then the line/DC link identification
starts automatically once the drive data is input into the archive.
Only then can it be guaranteed that the infeed operates with the optimum controller
settings.

undershoot. (Alarm threshold and shutdown threshold). The actual line voltage is
determined automatically and the adjustment is made based on this value.
