7.6.18.3 Engage clutch
The function is activated through a LH - transition at the input CLUTCH-CLOSE.
For the time required to start cam operation again, the function of the speed setpoint at
CLUTCH-NSET can be configured under C1410. The following alternatives are possible:
– Engage clutch immediately
– Set drive back to open-position, engage clutch
– Set drive to target position, engage clutch
– Latch at set position
After the selected function has been processed the output CLUTCH-OPEN is set to LOW.
Engage clutch immediately
l
C1410 = 0.
The output CLUTCH-OPEN is immediately set to LOW.
Set drive back to open-position
l
C1410 = 1.
The current position is stored by the input CLUTCH-PHI-ACT when the monitoring is activated or
aHL transition occurs at the input CLUTCH-CLOSE.
Note!
The actual position is not available.
AL H transition at the input CLUTCH-CLOSEstarts a profile generator which sets the drive back
to the open-position.
– Acceleration/deceleration time adjustable under C1412/2
– Max. speed adjustable under C1411/1
– A corresponding speed setpoint is output at -NSET.
CLUTCH-OPEN is set to LOW when the open-position is reached.
Set drive to target position
l
C1410 = 2
AL H transition at the input CLUTCH-CLOSEstarts a profile generator which sets the drive to the
target position. The target position must be selected through CLUTCH-PHI-SET.
– Acceleration/deceleration time adjustable under C1412/2
– Max. speed adjustable under C1411/1
A corresponding speed setpoint is output at CLUTCH-NSET.
CLUTCH-OPEN is set to LOW when the target position is reached.
Latch at set position
l
C1410 = 3
The drive remains in standstill until CLUTCH - PHI-ACT = CLUTCH - PHI-SET.
After a L -> H transition at the input CLUTCH-CLOSE:
– the speed setpoint = 0 is output at -NSET
– with CLUTCH - PHI-ACT =CLUTCH - PHI-SET output CLUTCH - OPEN is set to LOW
– Hysteresis adjustable under C1413/1
