Example: Hot-plugging
Using the hot-plugging function, components can be withdrawn from the operational drive line-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 all of
the drive objects or components involved must first be deactivated/parked using parameter
p0105 or STW2.7.
The following requirements must be satisfied:
Hot-plugging only functions when a drive object is connected in a star configuration to a Control
Unit or to the DRIVE-CLiQ Hub DMC20/DME20.
The system does not support removing DRIVE-CLiQ connections between the other DRIVE-
CLiQ components, e.g. Sensor/Terminal Module to Motor Module, Motor Module to 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
Drive functions
