3.16 Axis couplings
Examples
● 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")
● Wait for synchronism condition according to COUPDEF to be fulfilled: WAITC( )
Deactivate coupling COUPOF
COUPOF can be used to define the turn-off behavior of the coupling:
● Deactivation of coupling with immediate block change:
– COUPOF(S2,S1) (with specification of leading spindle)
– COUPOF(S2) (without specification of leading spindle)
● Deactivation of coupling after switch-off positions have been crossed. The block change
takes place after the switch-off positions have been crossed.
– COUPOF(S2,S1,150) (switch-off position FS: 150°)
– COUPOF(S2,S1,150,30) (switch-off position FS: 150°, LS: 30°)
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:
– COUPOFS(S2,S1) (with specification of leading spindle)
– COUPOFS(S2) (without specification of leading spindle)
● 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.
– COUPOFS(S2,S1,150) (switch-off position FS: 150°)
Delete couplings COUPDEL
COUPDEL deletes the coupling:
● COUPDEL(S2,S1) (with specification of leading spindle)
● COUPDEL(S2) (without specification of leading spindle)
Reset coupling parameters, COUPRES
COUPRES activates the coupling values parameterized in the machine and setting data:
● COUPRES(S2,S1) (with specification of leading spindle)
● COUPRES(S2) (without specification of leading spindle)
System variables
● Current coupling status of following spindle
The current coupling status of a following spindle can be read bit-coded via:
<Value> = $AA_COUP_ACT[<FS>]
