3.2.24.7 Selection of the target position in the disengaged state
Description
The target position is specified if the drive has to be set to a specific position in the disengaged state.
As the internal master angle corresponds to the target position, the tool position can be derived from
the internal master angle.

l The internal master angle (PHOUT) is running synchronously to the external master angle
(PHI−SET) until the braking position has been crossed.
– The braking position always is before the target position.
l
If the braking position is crossed, the drive is celerated to the speed at CLUTCH3−LOW−VEL.
– If CLUTCH3−LOW−VEL = 0, the internal master angle is exactly on the target position.
Adjustment
l
Set C1707 = 0.
l Define the target position at CLUTCH3−TARGET−POS.
l
Start the disengaging process with CLUTCH3−CLOSE = LOW.
3.2.24.8 Time−controlled disengaging in target position
Description
The function is required for applications with material transfer (e.g. placing caps on the bottles and
screwing them).
If there are no bottles in the machine, no caps may be feeded. The cap feed is disengaged for one
or several machine pulses, until bottles are available again. If disengaging is to be carried out, it may
only be started with the following machine pulse. In the disengaged state, the cap feed has to be in
a defined target position.
