Overview
SINAMICS G120 standard inverters
0.37 kW to 250 kW (0.5 hp to 400 hp)
Power Modules
PM240 Power Modules – 18.5 kW to 250 kW
(25 hp to 400 hp), IP20 degree of protection
PM240 Power Modules, frame sizes FSD to FSF
PM240 Power Modules, frame size FSGX
PM240 Power Modules have a braking chopper (four-quadrant
applications) and are suitable for a large number of applications
in general machinery construction.
The braking chopper is already integrated in frame sizes FSD
to FSF. For frame size FSGX, an optional pluggable Braking
Module can be ordered
(see section "DC link components")
.
The permissible cable lengths between inverter and motor
are limited. Longer cables can be used if output reactors are
connected
(see section "Load-side power components")
.
Line reactors are available to minimize line harmonics as well
as voltage and current peaks
(see section "Line-side power
components")
.
The PM240 Power Module is suitable for safety-oriented applica-
tions. In conjunction with a fail-safe Control Unit, the drive can be
transformed into a Safety Integrated Drive
(see section "Control
Units")
.
PM240 Power Modules in frame size FSGX (i.e. 160 kW/250 hp
and higher) are approved only for the Basic Safety functions
(STO, SS1 and SBC).
Power Modules with integrated line filter class A are suitable for
connection to TN systems. Power Modules without integrated
line filter can be connected to grounded TN/TT systems and
non-grounded IT systems.
Note:
Shield plates and shield connection kits are available. These can
be used in the wiring installation for the Control Units and
Power Modules to ensure that it complies with EMC guidelines.
For further information, see Shield connection kits and shield
plates for Control Units and Power Modules in section
Supplementary system components.
