Connecting several modules in parallel

In Startdrive, several Power Modules or several Motor Modules respectively can be
connected in parallel in vector control. 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.
Functionality of the parallel connection is identical for Motor Modules and Power Modules.

NOTICE
Damage to a sine-wave filter through incorrect parameter assignment
If a sine-wave filter is installed in your hardware configuration, the sine-wave filter can
be destroyed if it has not been set in the additional data of the Motor Module or Power
Module.
• Set the installed sine-wave filter in the "Output filter" drop-down list and add the
required filter parameter data.
