Activate synchronized mode
• Fastest possible activation of coupling with any
angle reference between LS and FS:
N ... COUPON (S2, S1)
• Activation with angular offset POS
Position-synchronized coupling for profiled
workpieces.
POS refers to the 0° position of the lead spindle
FS
in the positive direction of rotation.
Value range POS
COUPON (S2,S1,30)
You can use this method to change the angle offset
even when the coupling is already active.
Deactivate synchronized mode, COUPOF
Three variants are possible:
• For the fast possible activation of the coupling
and immediate enabling of the block change:
COUPOF (S2,S1)
• After the deactivation positions have been
crossed; the block change is not enabled until the
deactivation positions POS
appropriate, POS
Value range 0° ... 359.999°:
COUPOF (S2,S1,150)
COUPOF (S2,S1,150,30)
