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
for the power units.
In STARTER, parallel connection (Line Modules and Motor Modules) is activated 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.
