5. Notes
(1) Feedrate override is not supported for retracting.
(2) Interlock is supported for retracting.
(3) Machine lock is supported for retracting. Retract completion signal is output when retract
operation is completed in the machine lock condition.
(4) Feed hold is not supported for retracting.
(5) The mirror image (the signal or the setting) is invalid. Therefore, the direction of retract is
the direction of the machine coordinate. (The mirror image is valid for update of the
absolute coordinate.)
(6) When retract is executed during automatic operation, the control unit enters the feed hold
state at the same time as the retract operation starts.
(7) The acc./dec. of retract is the condition of the acc./dec. at retract execution.
(8) Retract operation stops, when Reset or Emergency-stop is executed during retract
movement. At this time, the retract completion signal is not turned to “1”.
(9) When the servo alarm or the OT alarm of the retract axis occurs during retract
movement, retract operation stops. At this time, the retract completion signal is not turned
to “1”. However, when an alarm except the OT alarm or the servo alarm occurs, retract
operation does not stop.
(10) Even if the retract signal RTRCT is turned to “0” after retract operation starting, retract
operation does not stop.
(11) The retract signal RTRCT is not accepted while the retract completion signal RTRCTF is
set to “1”.
(12) Even if thread cutting is executed, retract is effective. When the retract signal is input, the
thread cutting operation is stopped at once and retract operation is executed.
(13) Even if the retract is executed to the axis controlled by PMC, the movement command
for the PMC axis is not canceled. In this case, the PMC axis must be canceled by the
PMC axis reset signal ECLRg at the same time as the retract signal RTRCT is turned
to “1”.
(14) During advanced preview control mode, high-precision contour control mode (in
machining center series), or AI contour control mode (in machining center series), this
function is not used.
(15) This function is not used in high-speed cycle cutting or binary operation. In case of high-
speed cycle cutting or binary operation, the retract function for each function has to be
used.
