Integration
The Power Modules communicate with the higher-level control module via DRIVE-CLiQ. The Control Unit in this case could be a
CU310-2, CU320-2 or a SIMOTION D Control Unit. An external 24 V DC power supply is required to operate liquid-cooled Power
Modules.
Connection example of a liquid-cooled Power Module in the chassis format
Note:
The integrated 24 V power supply at connector X42 can have a
maximum load of 2 A. When the Control Unit is supplied from the
integrated power supply, the total load of the digital outputs must
be carefully observed to ensure that the 2 A is not exceeded.
