4.1 Default settings for the SINAMICS G120D
Factory default settings
The inverter system is shipped from the factory as a Control Unit and a Power Module.
Without any parameterization or after a factory reset, the inverter can be operated without
additional parameterization if the inverter default settings (which depend on the inverter type
and size) match the following data of a 4-pole motor:
Default line supply frequency 50 Hz
Rated motor voltage P0304
Rated motor current P0305
Rated motor power P0307
Rated motor frequency P0310
Rated motor speed P0311
(A Siemens standard motor is recommended.)
Further, the following conditions must be fulfilled:
Control (ON/OFF command) using digital inputs See pre-assigned inputs below.
Asyncronous motor P0300 = 1
Self-cooled motor P0335 = 0
Motor overload factor P0640 = 150 %
Min. frequency P1080 = 0 Hz
Max. frequency P1082 = 50 Hz
Ramp-up time P1120 = 10 s
Ramp-down time P1121 = 10 s
Linear V/f characteristic P1300 = 0
The Control Unit is intended to be control and operate the inverter utilizing the PROFIBUS or
PROFINET interface. The PROFIBUS or PROFINET interface may be used to further
configure and control the inverter as required.
4.2 Commissioning with the IOP
