5.5 Generic coupling
The block change criterion can be defined with the keyword CPBC or with the programming
command WAITC. The instruction programmed last is valid.

Coupling Block Change Criterium
Defines block change criterion with active coupling.
Type: STRING
Range of values:
"NOC" Block change is performed irrespective of the
coupling status.
"IPOSTOP" Block change is performed with setpoint
synchronism.
"COARSE" Block change is performed with actual value
synchronism "coarse".
"FINE" Block change is performed with actual value
synchronism "fine".
Default value: "NOC"
Comment
; Block change during processing of the part program is
done with setpoint synchronism (with active coupling to
following axis X2).
WAITC(FAx1,BC)
Wait for Coupling Condition
Defines block change criterion with active coupling.
