"IPOSTOP" Block change is performed with setpoint synchronism.
"COARSE" Block change is performed with actual value syn‐
chronism "coarse".
"FINE" Block change is performed with actual value syn‐
chronism "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.
Fax: Designates the following axis and therefore the coupling module.
BC: Defines the desired block change criterion.
