Controlled Power Modules
■
Design
The SINAMICS G110 standard inverters are equipped with a
control module and a power module, providing the inverter in the
CPM 110 version (Controlled Power Module) with a compact
and efficient design. They operate with the latest IGBT technol-
ogy and digital microprocessor control.
The SINAMICS G110 inverter product range consists of the
following variants and versions:
• The
analog variant
is available in the following versions:
- Without EMC filter, with heat sink
- With integrated EMC filter, class A/B, with heat sink
- Without EMC filter, with flat heat sink (FSA frame size only)
- With integrated EMC filter, class B, with flat heat sink (FSA
frame size only)
• The
USS variant
(RS485) is available in the following versions:
- Without EMC filter, with heat sink
- With integrated EMC filter, class A/B, with heat sink
- Without EMC filter, with flat heat sink (FSA frame size only)
- With integrated EMC filter, class B, with flat heat sink (FSA
frame size only)
For frame size FSA, cooling is achieved through a heat sink and
natural convection. Frame size FSA with flat heat sink offers
space-saving and favorable heat dissipation since an additional
heat sink can be installed outside the control cabinet. For frame
sizes FSB and FSC, an integrated fan is used to cool the heat
sink, making the compact design possible.
The connections for all inverter variants are easily accessible
and in the same location. To ensure optimum electromagnetic
compatibility and easy connection, the line and motor connec-
tions are located on opposite sides (as with contactors). The
control terminal block does not require screws to install it.
The optional BOP (Basic Operator Panel) can be installed with-
out the use of tools.

Function
•
The stress on the machine mechanical system is reduced by
using a skippable frequency range to avoid resonance
effects, selecting ramp-up/ramp-down times up to 650 s,
using ramp smoothing as well as being able to switch the
inverter to a spinning motor (flying restart circuit)
•
Increased plant availability as a result of automatic restarting
following a power failure or stoppage
•
Fast current limiting (FCL) for fault-free operation in the event
of sudden load surges
•
Parameterizable V/f characteristic (e.g. for synchronous
motors)
•
DC braking as well as compound braking for fast braking
without an external braking resistor
•
DC link voltage limiting using V
DCmax
controller
•
Slip compensation, electronic motorized potentiometer
function and three fixed speed setpoints
•
Parameterizable voltage boost for a higher dynamic
performance when starting and accelerating
•
Motor holding brake function to control an external
mechanical brake
