Programming function

7 a. 6

With these 2 bits you determine how coupled motion is to be performed.

00 ... no coupled motion

10 ... coupled motion in opposite directions

11 ... coupled motion in the same direction

01 ... not defined (Alarm 85)

The definition of the coupled motion combination can be changed on a warm restart

without POWER ON (for warm restart see also Section entitled ”Functional Descriptions”).
