Parking axis and parking sensor

4.12.1 Description
The parking function is used in two ways:
S "Parking sensor"
– Monitoring of a certain encoder is suppressed.
– The encoder is prepared for the "removed" state.
S "Parking axis"
– Monitoring of all encoders and Motor Modules assigned to the "Motor
control" application of a drive are suppressed.
– All encoders assigned to the "Motor control" application of a drive are
prepared for the "removed" state.
– The Motor Module that is assigned the application "Motor control" of drive is
prepared for the state "removed Motor Module".
Parking a sensor
When a sensor is parked, the sensor being addressed is switched to inactive
(r0146 = 0).
S Control is carried out via the sensor control/status words of the cyclic telegram
(Gn_STW.14 and Gn_ZSW.14).
S With a parked motor measuring system, the associated drive must be brought
to a standstill by the higher-level control system (disable pulses
e.g. via STW1.0/OFF1).
S The monitoring functions for the power section remain active (r0126 = 1).
Parking an axis
When an axis is parked, the power section and all the sensors assigned to the
"motor control" are switched to inactive (r0146[n] = 0).
S Control is carried out via the control/status words of the cyclic telegram
(STW2.7 and ZSW2.7) or using parameters p0897 and r0896.0.
S The drive must be brought to a standstill by the higher-level controller (disable
pulses e.g. via STW1.0/OFF1).
S DRIVE-CLiQ communication to downstream components via the deactivated
power section (r0126 = 0) remains active.
S A measuring system that is not assigned to the "motor control" (e.g. direct
measuring system) remains active (r0146[n] = 1).
S The drive object remains active (r0106 = 1).
