1. General
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.
- Feedrate in retract is set to the parameter No.7740. Then the feedrate override is not
effective.
- During the movement in retract, feed hold is not effective.
- 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.
- The retract completion signal is turned to “0” when any retract axis is moved.
This function is used, for example, to prevent the damage of tool or workpiece when
unexpected disturbance occurs during machining, and so on.
Retract movement
Machining direction
: The movement of the auto mode is feed hold state.
