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).
6.13.2 Example: parking axis and parking sensor
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 CTW1.0 (OFF1). All components assigned to
the motor control (e.g. power unit and motor encoder) are shut down.

Example: parking sensor
In the following example, a motor sensor is parked. To ensure that the motor sensor parking
is effective, the drive must be brought to a standstill (e.g. via CTW1.0 (OFF1).
