Possibilities for the position selection

The following options are available for the selection of different positions:

1. Changeover of profiles
2. Changing the profile position via parameter data (SDO)
3. Changing the profile position via process data (PDO)

• The profile position is defined in [increments] or in the application unit [units].

Possibility 1: Changeover of profiles
A total of 15 profiles is available in the 8400 TopLine.

• A profile describes a motion task that can be converted into a rotary motion by the Motion

Control Kernel in the "Positioning" operating mode.
