Parallel switching of Motor Modules

The following rules must be followed for parallel switching of Motor Modules:
• Up to four identical Motor Modules can be switched parallel.
• Parallel switching can only be implemented with a common Control Unit.
• The length of the motor supply lines must be the same (symmetric structure).
• The motor modules must be supplied by a common intermediate circuit.
• For motors with a development system supply line with a minimum line length must be
used, the respective line lengths are shown in the tables below.
• A derating factor of 5 % must be taken into account, regardless of the number of Motor
Modules switched in parallel.
Minimum line lengths for parallel switching and connection to a motor with development system
Attention
The minimum motor line lengths shown in the tables below must be complied with for parallel
switching of two or more Motor Modules, and connection to a motor with a development
system. If the required line length cannot be achieved in the application then a motor reactor
must be provided.
