Electrical Installation - Siemens SINAMICS G110M Operating Instructions Manual

Power Module (PM), in this case, the standby current of the Converter increases, by an
additional current of 15 mA.
The standby currents for all the possible combinations of the SINAMICS G110M are given in
the following table:
Table 4- 3
Device
G110M FSA (0.37 ... 1.5 kW)
G110M FSB (2.2 ... 4.0 kW)
G110 FSA + Optional 24 V PSU or
External 24 V
G110 FSB + Optional 24 V PSU or
External 24 V
PROFIBUS / USS CM only
PROFINET / AS-i CM only
* The optional 24 V PSU is an orderable item which is designed specifically for use with the
SINAMICS G110M converter. The 24 V PSU is fitted to the terminal housing as shown in
stalling the 24V power supply (Page 54). The external 24 V supply is sourced by the user and is
connected to the converter through the 24 V connections as shown in
(Page 65).
The maximum combined current for all digital inputs is 200 mA, the maximum combined currents for
all the digital outputs is 500 mA.
Thermal stability of the system
The SINAMICS G110M system is comprised of a motor and a converter which are
designed to work together. The system can generate a significant amount of heat which
can affect the performance of your application.
If the duty cycles of the system are not calculated properly, it could result in your application
not working efficiently and produce nuisance trips from overtemperature faults.
To ensure the thermal stability of the system, duty cycles should be calculated using the
lowest rated component of the system - this should be either the motor or the converter
depending on the your application.
NOTICE
Line impedance
To ensure trouble free operation we recommend the mains supply impedance is less than
1% (RSC > 100).
