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”).
