10.14 Axis Interlock Input Signal
The axis interlock input signal is “opened” during axis movement, the corresponding axis stops
after deceleration. When the signal is “closed” after that, the axis continues moving for the
remaining distance, the program to the next block after the completion of axis movement.
For two or three axis simultaneous interpolation, if the axis interlock signal of any one of these
axis is “opened”, interpolation processing is prohibited and the axes stop after deceleration.
SUPPLEMENT
If this input signal is “opened” while the CNC is in the cycle start state, the STL remains open.
10.15 Direction Specified Axis Interlock Input Signal
These input signals are interlok input signals which are used to disable axis movement only in the
specified direction. The signal is provided for the individual axes.
If this input signal is “opened” while an axis is moving, the axis decelerates to a stop. When it is
“closed” in the state the axis stops, the axis continuously moves by the remaining distance. After
the completion of movements, the program advances to the next block.
These signals are valid regardless of the operation mode.
If the axis interlock signal (#30780 to #30784) is “open”, axis movement is disables in both the
positive and negative directions disregarding of he status of the direction specified axis interlock
input signals.
During interpolation operation by simultaneous multiple axis movements, if any one of the input
signals of the corresponding axis movement direction is “opened”, all axes stop after deceleration.
SUPPLEMENT
In the circular interpolation operation, these signals function as the normal axis interlock regard-
less of the direction of of movement.
