2.9 Commissioning of power units connected in parallel
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. Suitable "total values" are derived from the individual values of the
power units.
Only power units in the "chassis" format are released for a parallel connection:
● Infeeds
● Motor Modules for vector control
When commissioning the power units for the first time, activate the parallel connection via
the wizards in the STARTER commissioning tool. Select the parallel connection when
selecting the power unit (infeed and/or Motor Module) according to the following diagrams as
option:
