6.20 Parking axis and parking encoder
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
● With a parked motor measuring system, the associated drive must be brought to a
● The monitoring functions for the power unit remain active (r0126 = 1).
Note
Removing/replacing parked components
Once parked components have been disconnected/connected, they can only be unparked
once they have been successfully integrated in the actual topology (see r7853).
Example: Parking axis
In the following example, an axis is parked. To ensure that the axis parking is effective, the
drive must be brought to a standstill (e.g. via STW1.0 (OFF1). All components assigned to
the motor control (e.g. power unit and motor encoder) are shut down.
