Mains And Dc Link Identification Of The Infeed Module - Siemens SINUMERIK 840D sl Commissioning Manual

Commissioning NC-controlled drives
6.9 Tips for commissioning the SINAMICS drives
● The actual line frequency for the infeed is determined automatically. In parameter p0284,
p0285 you set the warning threshold at which an alarm is triggered (presetting of the
monitoring function: 45 Hz to 65 Hz).
● Quick stop for axes when the voltage dips after a delay time in [ms]:
In the event of a voltage dip, alarm 207862 "External fault 3" is triggered, followed by alarm
207841 "Drive: Infeed operation withdrawn", and the associated fault response is initiated
from p2101. If an alarm is not to be initiated for very short voltage dips, this can be configured
with the ON-delay time p2101.
The switch-on delay is not active for each specific drive, but per infeed – and therefore for
all the drives connected to this infeed. This does not affect alarms, for example from the DC
link, and they continue to be triggered.

Mains and DC link identification of the infeed module

Objective
To optimally set the current and voltage control, start a mains and DC link identification after
completing the commissioning of the drive.
Automatic identification
The automatic identification determines characteristic mains and DC link characteristics, which
serve as the basis for optimally set controllers in the Line Module. You can adapt the dynamics
of the voltage control with p3560.
