Check The Line Data Of The Infeed - Siemens SINUMERIK 840D sl Commissioning Manual

6.9.2

Check the line data of the infeed

Checking and setting the power data
Finally, after commissioning the drive system, check the power data of the infeed module. In the
operating area "Commissioning" → "Drive system" → "Infeed", the "Power data" softkey is
enabled if the infeed module has already been commissioned and the data have been saved
in the non-volatile memory:
The following power data are configured:
● When the checkbox is selected, the line/DC link identification is activated once the infeed
pulse has been enabled (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 "Line 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.
● Enter the device connection voltage: This is the basis for the mains overvoltage (p0281 -
p0283), for which an alarm is issued when the threshold is exceeded or undershot (warning
threshold and trip threshold). The actual line voltage is determined automatically and the
adjustment is made based on this value.
