Commissioning

During commissioning, power units connected in parallel are treated like a power
unit on the line or motor side. With parallel connection, the parameter display for
the actual values changes only slightly. Instead, suitable "total values" are derived
from the individual values of the power units.
In STARTER, the parallel connection (Line Modules and Motor Modules) are acti-
vated via the Wizard. You can also select parallel connection when choosing the
power unit. You then have to specify the number of power units to be connected in
parallel.
