Example, hot plugging

Description
Using the hot-plugging function, components can be withdrawn from the operational drive
line-up (the other components continue to operate) on the DRIVE-CLiQ line. This means that
the corresponding drive object must first be deactivated/parked beforehand using parameter
p0105 or STW2.7.
The following requirements must be met:
Hot plugging is only possible when a drive object is connected in a star configuration to a
Control Unit or to the DRIVE-CLiQ Hub DMC20.
The system does not support removing DRIVE-CLiQ connections between the other DRIVE-
CLiQ components e.g. Sensor/Terminal Module to the Motor Module, Motor Module to the
Motor Module.
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
with pulse inhibit.
