Figure 7.6
Jog Retract Operation
Jog retract exit moves
Jog retract return moves
In Figure 7.6 notice that the control only recognized 6 jog moves upon
returning instead of the actual 11 moves that were made to retract the tool.
This is because the jog retract feature records consecutive jog moves on the
same axis as one move.
CAUTION: If the number of jog retract moves performed
exceeds the maximum allowed number set in AMP, the control
will move the cutting tool directly from the final point of jog
retract to the last remembered jog retract point along a straight
line when <CYCLE START> is pressed. Then the tool will be
returned in the normal jog retract fashion.
