Integration
PM240 Power Modules communicate with the Control Unit via
the PM-IF interface.
PM240 Power Modules have the following interfaces as stan-
dard:
• PM-IF interface to connect the PM240 Power Module to the
Control Unit. The PM240 Power Module also supplies power to
the Control Unit using an integrated power supply
• Terminals DCP/R1 and R2 for connection of an external bra-
king resistor, valid up to frame size FSF. For frame size FSGX,
an external plug-in braking unit (Braking Module) is required
to connect a braking resistor
• Motor connection using screw terminals or screw studs
• Control for the Brake Relay or the Safe Brake Relay for control-
ling a motor brake
• 2 PE/protective conductor connections
