Basic functions

8.22 Parking axis / parking encoder

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.

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 STW1.0/OFF1).

● The monitoring functions for the power unit remain active (r0126 = 1).

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).
