3.2.24.6 Selection of the disengaging position
Description
The disengaging position is specified if an operation has to be completed before the disengaging
process may be initiated.

The internal master angle (PHOUT) is running synchronously to the external master angle (PHI−SET)
until the position at CLUTCH3−TARGET−POS is crossed. Then drive is decelerated to the speed at
CLUTCH3−LOW−VEL.
Adjustment
l Set C1707 = 1.
l Define the disengaging position at CLUTCH3−TARGET−POS.
l Start the disengaging process with CLUTCH3−CLOSE = LOW.
