Design
PM240-2 Power Modules, frame sizes FSA to FSF (with Control Unit and
Operator Panel)
The PM240-2 Power Modules in blocksize format feature the
following connections and interfaces as standard:
•
Line supply connection
•
PM-IF interface for connection of the PM240-2 Power Module
and CU310-2/SIMOTION D410-2 Control Unit or
CUA31/CUA32 Control Unit Adapter. The PM240-2 Power
Module also supplies power to the
CU310-2/SIMOTION D410-2 Control Unit or CUA31/CUA32
Control Unit Adapter by means of an integrated power supply
•
Terminals DCP/R1 and R2 for connection of an external
braking resistor
•
Motor connection using screw terminals or screw studs
•
Control circuit for the Safe Brake Relay for controlling a
holding brake
•
2 PE/protective conductor connections
Power Modules without integrated line filter can be connected to
grounded TN/TT systems and non-grounded IT systems. Power
Modules with integrated line filter are suitable only for connec-
tion to TN systems with grounded neutral.
Push-through variant
The push-through variant allows the cooling fins of the Power
Module to be pushed through the rear panel of the control
cabinet. Push-through versions should be used in applications
where the amount of power loss generated inside the control
cabinet itself must be minimized.
The scope of delivery of Power Modules includes shield connec-
tion kits used for EMC-compliant installation of Power Modules.
