5.2.2 Set counting direction
The counting direction can be reversed in commissioning mode online using bit 28. The coder re-
turns the current direction after the changeover to the master. A 0 means the counting direction is
clockwise (looking toward the shaft) and 1 means anti-clockwise.

5.2.3 Scaling the module in the teach in process
This process makes it possible to automatically scale the module. After starting the process, the
system is moved along a defined path. Then after the process is stopped, the number of steps
into which the travelled path should be divided is input. The path of travel may not exceed 2047
revolutions.

process value output with scaling factor 1

After this function, the gear factor is set to 1 and the drift (preset) is deleted.
Now the system must be moved the defined path. The path of travel is displayed unscaled by
process value output.
