Current derating factor and permissible output current with sine-wave filter
Furthermore, space vector modulation SVM is the only permitted modulation mode.
As a result, the achievable output voltage for G130, G150 and S120 Motor Modules which are supplied by Basic or
Smart Infeeds is limited to 85 % (380 V to 480 V) or 83 % (500 V – 600 V) of the input voltage. In consequence, the
drive switches earlier to field-weakening operation. As the converter cannot supply the rated voltage of the motor, the
motor can operate at rated output only if it is supplied with a current in excess of its rated current.
With S150 and S120 Motor Modules that are supplied by Active Infeeds, the DC link voltage is so high, as a result of
the step-up converter operating principle of the Active Infeed, that the voltage applied to the motor reaches the line
supply value even in space vector modulation mode.
The maximum output frequency is limited to 150 Hz.
The following table lists the permissible motor cable lengths with sine-wave filter for SINAMICS G130, G150, S150,
S120 Motor Modules (Chassis and Cabinet Modules).

Maximum permissible motor cable lengths with sine-wave filters for SINAMICS G130, G150, S150
and SINAMICS S120 Motor Modules in format Chassis and Cabinet Modules
These cable lengths apply to drives on which only one motor is connected to the filter output. Longer motor cable
lengths can be used for drives with multiple motors. Please refer to section "Motor reactors" for information on how to
calculate the permissible motor cable lengths for multi-motor drives. If this calculation method is used for converters
with sine-wave filters, it has to be taken in account that instead of the maximum number of parallel cables n
the maximum cross-sections A
The sine-wave filter should be sited in the immediate vicinity of the converter or inverter output. The cable length
between the sine-wave filter and the output of the converter or inverter should not exceed about 5 m.
Sine-wave filters must be selected with parameter P0230 when the drive is commissioned.
P230 must be set to "3" for sine-wave filters of the SINAMICS converter range. This ensures that all the required
parameter changes relating to the sine-wave filter are made correctly.
P230 must be set to "4" for sine-wave filters supplied by manufacturers other than Siemens. In this case, the
technical data of the sine-wave filter must be entered in other parameters.
Sine-wave filters can be used in both grounded systems (TN/TT) and non-grounded systems (IT).
