- 293 -
NOTE
1 Interlock is supported for retracting.
2 Machine lock is supported for retracting. Retract completion
signal is output when retract operation is completed in the
machine lock condition.
3 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.)
4 When retract is executed during automatic operation, the
control unit enters the feed hold state at the same time as the
retract operation starts.
5 Automatic operation is impossible when the tool is retracted.
A cycle start results in the warning message "Impossible to
start (the tool is retracted)" being displayed.
6 Nonlinear interpolation type positioning is used in retracting
the tool.
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 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 RSTx at the same time as the retract signal
RTRCT is turned to ”1”.
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 canned cycle cutting (tapping or rigid tapping) is
executed, retract is effective. When the retract signal is input,
the canned cycle cutting operation is stopped at once and
retract operation is executed.
