Siemens SINAMICS S120 Function Manual page 827

The complete drive object (Motor Module, motor encoder, Sensor Module) is disabled via
p0105.
STW2.7 is used to set the function "Park axis" for all components that are assigned to the
motor control (Motor Module, motor encoders). All components that belong to Encoder_2 or
Encoder_3 remain active. The "Park axis" function is only enabled by setting the ZSW2.7 bit
in combination with pulse inhibit.
Note
Drives with enabled Safety functions must not be deactivated, see Section "Safety
Integrated" for further details.

Note
In order to disconnect and isolate the power unit from the DC link, additional measures must
be applied - such as DC-link wiring through the DC-link infeed adapter and DC-link
disconnecting devices. The safety information and instructions in the Equipment Manual
must be carefully observed.
