Activation and deactivation
End-of-motion criterion IPOBRKA and precise time of activation.
For part program execution:
● The braking ramp end-of-motion criterion can be activated via the NC command
● The precise time of activation is defined in setting data
● IPOBRKA is deactivated when an axis end-of-motion criterion FINEA, COARSEA or
● The NC command ADISPOSA can be used to program the size of the tolerance window
For technology cycles:
● The braking ramp end-of-motion criterion can be activated via the synchronized action
● IPOBRKA is deactivated when the axis end-of-motion criterion FINEA, COARSEA or
● The size of the tolerance window for the braking ramp end-of-motion criterion can be
Examples
For block change condition "Braking ramp" in the part program:
N10 POS[X]=100
N20 IPOBRKA(X,100)
N30 POS[X]=200
N40 POS[X]=250
