1. AXIS CONTROL
345
When the retract signal RTRCT is turned to ”1” (the rising edge is
detected) in auto mode or manual mode, the axis set in bit 0 (RTR) of the
parameter No.7730 moves (retracts) by the amount set in the parameter
No.7741.
Upon the completion of retraction, the retract completion signal RTRCTF
is output.
S Feedrate in retract is set to the parameter No.7740. Then the feedrate
override is not effective.
S During the movement in retract, feed hold is not effective.
S In case that retract signal is turned to ”1” in auto mode, the movement
of the auto mode is feed hold state and the retract movement is done.
S The retract completion signal is turned to ”0” when any retract axis is
moved.
Retract movement
Machining direction : The movement of
the auto mode is feed
hold state.
This function is used, for example, to prevent the damage of tool or
workpiece when unexpected disturbance occurs during machining, and so
on.
