SINAMICS S110 servo drives
0.12 kW to 90 kW (0.16 hp to 125 hp)
PM340 Power Modules in blocksize format
■
Overview
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 supply connection
•
PM-IF interface for connection of the PM340 and CU305
Control Unit. The PM340 Power Module also supplies power
to the CU305 Control Unit by means of an integrated power
supply.
•
Terminals DCP/R1 and R2 for connection of an external
braking resistor
•
Motor connection made with screw-type terminals or screw
studs
•
Control circuit for the Safe Brake Relay for controlling a
holding brake
•
2 PE/protective conductor connections
PM340 Power Modules without integrated line filter can be
connected to grounded TN/TT and non-grounded IT systems.
PM340 Power Modules with integrated line filter are suitable only
for connection to TN systems with grounded star point.
The integrated braking unit (braking chopper) is rated with the
capability to continuously utilize the external braking resistor.
The temperature of the external braking resistor must be
monitored to provide protection against thermal overloading.

Integration
PM340 Power Modules communicate with the CU305 Control
Unit via the PM-IF interface.

Note:
Operation of SINAMICS S110 in conjunction with PM240-2
Power Modules will become possible with a service pack
planned for firmware V4.4.
