Handwheel override in automatic mode
Positioning axis
Syntax for handwheel override:
Example 1:
Activate velocity override
N10 POS[U]=10 FDA[U]=100 POSA[V]=20 FDA[V]=150 . . .
POS[U]=10
FDA[U]=100
POSA[V]=20
FDA[V]=150
Example 2:
Activate path default and velocity override in the same NC block
N20 POS[U]=100 FDA[U]= 0 POS[V]=200 FDA[V]=150 . . .
POS[U]=100
FDA[U]= 0
POS [V]=200
FDA[V]=150
Path axis
Syntax for handwheel override:
To program "Handwheel override in automatic mode" for path axes, the following
preconditions must have been met:
● Active movement commands from group 1: G01, G02, G03, CIP
● Exact stop active (G60)
● Linear feedrate in mm/min or inch/min active (G94)
These preconditions are checked by the control and an alarm is output if any of them is not met.
