7.2.7 Parking axis and parking encoder
The parking function is used in two ways:
● "Parking axis"
– Monitoring of all encoders assigned to the "motor control" application of a drive is
suppressed.
– All encoders assigned to the "Motor control" application of a drive are prepared for the
"removed" state.
● "Parking encoder"
– Monitoring of a certain encoder is suppressed.
– The encoder is prepared for the "removed" state.
Parking an axis
When the axis is parked, the power unit and all the encoders assigned to "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).
● 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.
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 (p1990).
A new encoder must be referenced again (e.g. to determine the machine zero point).
Parking an encoder
When an encoder is parked, the encoder being addressed is switched to inactive (r0146 =
0).
● Control is carried out via the encoder 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).
