Fig. 3−67 Angle diagram and path−time diagram: Time−controlled disengaging in target position
External master angle at CLUTCH3−PHI−SET
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 Target 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 internal master angle (PHOUT) synchronically follows the master value to the brake
position. At the brake position the braking process is started.
– The brake position is automatically calculated from the deceleration time Ti.
– The brake position is variable and depends on the current machine speed.
l If the target position is reached, the braking process is completed.
l
If CLUTCH3−LOW−VEL = 0, the internal master angle (PHOUT) is 0 at the target position.
Adjustment
l Set C1707 = 0.
l
Define the target 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.
