Parking axis and parking encoder

4.11 Parking axis and parking encoder
4.11.1 Description
The parking function is used in two ways:
S Parking encoder
-- Monitoring of a certain encoder is suppressed.
-- The encoder is prepared for the "removed encoder" 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 encoder" state.
-- The Motor Module assigned to the "Motor control" application of a drive is
prepared for the "removed Motor Module" state.
Parking an encoder
When an encoder is parked, the encoder being addressed is switched to inactive
(r0146 = 0).
S Control is carried out via the encoder 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 unit and all the encoders assigned to the "motor
control" are switched to inactive (r0146[n] = 0).
S Control is carried out via the encoder control/status words of the cyclic telegram
(STW2.7 und ZSW2.7) or via parameters p0897 and r0896.0.
S The drive must be brought to a standstill by the higher-level control system
(disable pulses e.g. via STW1.0/OFF1).
S DRIVE-CLiQ communication to downstream components via the deactivated
power unit (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).
