SINAMICS G150 – A Global Product
SINAMICS G150 is a global product. However, regional
differences in regulations, standards, specifications and
voltage levels for power and control require modifications
to the packaging (enclosure) and auxiliary components.
SINAMICS G150 enclosed drives are therefore offered in
versions designed to IEC (European) as well as to NEMA
(North American) standards.
SINAMICS G150 designs to NEMA vs. to IEC standards
All models of SINAMICS G150 (NEMA or IEC, type A or type
C) use the identical basic drive and electronics components
– power module of a particular power and voltage rating,
CU320-2 control unit, CompactFlash card with firmware,
AOP30 operator panel and TM31 input/output module as
well as optional modules (SMC30 encoder interface, VSM10
voltage sensing module, CBE20 PROFINET communications
module, etc.).
Differences between the NEMA and IEC versions are found
in the configuration of the base units, i.e. the enclosure type
and the scope of auxiliary equipment/options included, as
well as the offered range of standard and custom options.
Below is an overview of some of the more significant
differences between NEMA and IEC versions (not a
complete list!).
