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 at the start of synchronising
PHI−ACT Position of the internal master angle at CLUTCH3−PHI−ACT at the start of synchronising
Start position Position of the external master angle at which synchronising is initiated
Sync position Position from which the external and internal master angles run synchronously
OPEN If CLUTCH3−OPEN switches to LOW, the clutch is engaged
ACC/DEC During the process of engaging the clutch, CLUTCH3−ACC/DEC = HIGH
l The sync position is calculated from the acceleration (C1706/3) and the speed of the external
master angle. From this, also the start position results.
l From the sync position, the external and internal master angles are synchronous with regard
to speed and angle (position).
Adjustment
l Set C1707 = 0 or C1707 = 1. The process of engaging the clutch is the same for both modes.
l Set the desired acceleration in C1706/3.
