Maximum permissible motor cable lengths with sine-wave filter for SINAMICS G130, G150, S150
and SINAMICS S120 Motor Modules in Chassis and Cabinet Modules format
These cable lengths apply to drives on which only one motor is connected to the filter output. Longer motor cable
lengths may be used for drives with multiple motors at the filter output. Please refer to section "Motor reactors" for
information on how to calculate the permissible motor cable lengths drives with multiple motors. If the calculation
method described in this section is applied for converters with sine-wave filters, it must be noted that the relevant

1.10.3.2 Supplementary conditions which apply when sine-wave filters are used

It must be noted that the sine-wave filter should be sited in the immediate vicinity of the converter or inverter output in
the case of SINAMICS G130 and S120 Chassis units. The cable length between the sine-wave filter and the output of
the converter or inverter should not exceed about 5 m.
To make allowance for resonant frequency, the pulse frequency setting for systems with sine-wave filters is fixed at
4 kHz (380 V – 480 V) or at 2.5 kHz (500 V – 600 V). For this reason, the permissible output current is reduced to the
values given in the table below.

Current derating factor and permissible output current with sine-wave filter
Space vector modulation is the only permitted modulation mode on systems with sine-wave filters, i.e. they are not
compatible with pulse-edge modulation.
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 % of the input voltage (380 V to 480 V) or to 83 % of the input voltage (500 V – 600 V). As a
consequence, the drive starts earlier to operate in the field-weakening range. 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.
In operation with sine-wave filters, the maximum output frequency is limited to 150 Hz (380 V – 480 V) or 115 Hz
(500 V – 600 V).
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. This setting effects an
overload reaction without pulse frequency reduction (p290=0 or 1) and sets the modulator mode to space vector
modulation without overmodulation (p1802=3). In addition, the technical data of the sine-wave filter must be entered
in parameters p233 and p234. The maximum frequency or maximum speed (p1082) and pulse frequency (p1800)
must also be set according to the data sheet of the sine-wave filter. For further information, please refer to the List
Manuals / Parameter Descriptions.
Sine-wave filters can be used in both grounded systems (TN/TT) and non-grounded systems (IT).
Sine-wave filters are compatible only with vector and V/f control modes, but not with servo control mode.
