Programmable block change behavior WAITC
WAITC can be used to define block change behavior, for example after a change to coupling
parameters or positioning actions, with a variety of synchronism conditions (coarse, fine,
IPOSTOP). If no synchronism conditions are specified, the block change behavior specified in
the COUPDEF definition will apply.
Example:
Wait for synchronism condition according to COUPDEF to be fulfilled
WAITC( )
Wait for synchronism condition FINE to be fulfilled for following spindle S2 and COARSE to be
fulfilled for following spindle S4:
WAITC(S2,"FINE",S4,"COARSE")
Deactivate coupling COUPOF
COUPOF can be used to define the turn-off behavior of the coupling:
• Deactivation of coupling with immediate block change:
-
-
• Deactivation of coupling after switch-off positions have been crossed. The block change
takes place after the switch-off positions have been crossed.
-
-
Deactivate coupling with following spindle stop COUPOFS
COUPOFS can be used to define the turn-off behavior of the coupling with following spindle
stop:
• Deactivation of coupling with following spindle stop and immediate block change:
-
-
• Deactivation of coupling after switch-off positions have been crossed with following
spindle stop. The block change takes place after the switch-off positions have been
crossed.
-
Delete couplings COUPDEL
COUPDEL deletes the coupling:
• COUPDEL(S2,S1) (with specification of leading spindle)
• COUPDEL(S2) (without specification of leading spindle)
