6.13 Parking axis and parking sensor
6.13.1 Description
The parking function is used in two ways:
● "Parking sensor"
– Monitoring of a certain encoder is suppressed.
– The encoder is prepared for the "removed" state.
● "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).
● Control is carried out via the sensor control/status words of the cyclic telegram
(Gn_STW.14 and Gn_ZSW.14).
● 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 CTW1.0/OFF1).
● The monitoring functions for the power unit remain active (r0126 = 1).
Parking an axis
When an axis is parked, the power unit and all the sensors assigned to the "motor control"
are switched to inactive (r0146[n] = 0).
● 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.
● The drive must be brought to a standstill by the higher-level controller (disable pulses e.g.
via STW1.0/OFF1).
● DRIVE-CLiQ communication to downstream components via the deactivated power unit
(r0126 = 0) remains active.
● A measuring system that is not assigned to the "motor control" (e.g. direct measuring
system) remains active (r0146[n] = 1).
● The drive object remains active (r0106 = 1).
