6.19 Parking axis and parking encoder
The parking function is used in two ways:
● "Parking axis"
● "Parking encoder"
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).
● Control is carried out via the control/status words of the cyclic telegram (STW2.7 and
● The drive must be brought to a standstill by the higher-level controller (disable pulses e.g.
● DRIVE-CLiQ communication to downstream components via the deactivated power unit
● A measuring system that is not assigned to the "motor control" (e.g. direct measuring
● The drive object remains active (r0106 = 1).
Note
Once the "Parking axis" / "Parking encoder" status has been canceled, you may have to
carry out the following actions:
• If the motor encoder has been replaced: determine the commutation angle offset
• A new encoder must be referenced again (e.g. to determine the machine zero point).

– 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".
– Monitoring of a certain encoder is suppressed.
– The encoder is prepared for the "removed" state.
