PM340 Power Modules in blocksize format, frame sizes FSA to FSF
The PM340 Power Modules in blocksize format feature the
following connections and interfaces as standard:
•
Line connection
•
DCP/R1 and DCN DC link terminals
•
PM-IF interface for connection of the PM340 Power Module
and CU310-2 Control Unit or CUA31 Control Unit Adapter. The
PM340 Power Module also supplies power to the CU310-2
Control Unit or CUA31 Control Unit Adapter by means of an
integrated power pack
•
Terminals DCP/R1 and R2 for connection of an external
braking resistor
•
Motor connection using screw-type terminals or screw studs
•
Control circuit for the Safe Brake Relay for controlling a
holding brake
•
2 PE connections
Power Modules without integrated line filter can be connected
to grounded star (TN, TT) and non-grounded symmetrical IT
systems. Power Modules with integrated line filter are suitable
only for connection to TN systems with grounded neutral.
The integrated Braking Module is rated with the capability to
continuously utilize the external braking resistor. The tempera-
ture of the external braking resistor must be monitored to provide
protection against thermal overloading.
