5 POSITIONING DEDICATED SIGNALS
(7) Axis interlock (Forward)/(Reverse) (M4406+10n/M4407+10n)
This signal is used to select whether an axis is made deceleration stop during
positioning control.
(a) The axis interlock (forward)/(reverse) command turns on while the axis
interlock valid/invalid (M4418+10n) is turning on, a deceleration stop is
executed in the applicable axis.
• ON.......... Valid: If the axis interlock (forward)/(reverse) command turns
• OFF........ Invalid: A deceleration stop is not executed in the applicable
(b) The interlock is valid in the following cases.
• Positioning control using the Motion program (Except for hige speed
oscillate (G25))
• Home position return
• Manual pulse operation
(c) The interlock is invalid at the "home position return" and "hige speed
oscillate".
(d) Deceleration stop is executed follows "deceleration stop time" by the
parameter block. However, a deceleration stop at the manual pulse
operation only is "a stop without deceleration processing".
(e) If the axis interlock of travel direction turns on with at least one axis,during
interpolation control, a deceleration stop is executed in all interpolation
axes.
(f) When the travel of axis stops by the axis interlock, a minor error "axis
interlock" (error code: 292) will occur.
In this case, since the program is not ended, the start accept flag (M2001 to
M2032) of applicable axis does not turn off.
Therefore, when the Motion program is started by the specification of
applicable axis, a minor error "the start accept flag (M2001 to M2032) for
applicable axis is ON." (error code: 101) will occur.
(g) When the axis interlock signal turns on at a Motion program start, after the
servomotor travels minutely, a minor error "axis interlock" (error code: 292)
will occur and a deceleration stop is made. (The servomotor does not travel
during JOG operation or manual pulse operation, and a minor error" axis
interlock" (error code: 292) will occur.)
on during execution of the Motion program, a
deceleration stop is executed in the applicable axis.
