3.2.24.9 Time−controlled disengaging at disengaging position
Description
In the case of printing machines, the last process (printing) must be completed before the tool or the
drive may be disengaged.

Fig. 3−68 Angle diagram and path−time diagram: Time−controlled disengaging at disengaging position
0 External master angle at CLUTCH3−PHI−SET
1
Internal master angle at CLUTCH3−PHI−ACT
PHI−SET Position of the external master angle at CLUTCH3−PHI−SET after completion of the disengaging process
TARGET−POS Disengaging position specified at CLUTCH3−TARGET−POS
OPEN
If CLUTCH3−OPEN switches to HIGH, the clutch is disengaged
ACC/DEC During the disengaging process, CLUTCH3−ACC/DEC = HIGH
l The external master angle (PHI−SET) and the internal master angle (PHOUT) run synchronously
until the disengaging position is reached.
l If the external master angle (PHI−SET) crosses the disengaging position, the braking process is
initiated.
l The position of the internal master angle (PHOUT) results from the deceleration time Ti and the
machine speed.
l If CLUTCH3−LOW−VEL = 0, the internal master angle (PHOUT) is placed on the standstill
position (PHOUT = 0), when the disengaging position has been crossed and the braking
distance (DIST) has been travelld.
Adjustment
l Set C1707 = 1.
l Define the disengaging position at CLUTCH3−TARGET−POS.
l Set the deceleration time Ti [s] in C1706/2.
l Define the external master angle at CLUTCH3−PHI−SET.
