Parking an encoder

When an encoder is parked, the encoder being addressed is switched to inactive (r0146 =

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

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.

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
