NC FUNCTION
292
Axis feed specified to each axis can be stopped separately. If interlock is
specified to any of the moving axis during cutting feed, all axes of the
machine movement will decelerate to a stop. When interlock signal is
reset, the moving starts.
Feed of all axes can be inhibited. When all axes interlock is commanded
during move, it decelerates and stops. When all axes interlock signal is
reset, the moving restarts.
Feeding of a specific axis in a specific direction can be inhibited
independently of other axes. If the interlock signal is input to any of the
axes during a cutting feed operation, all axes decelerate and come to a
stop. When the interlock signal for each axis direction is released, the axes
start moving again.
This function is usable for both the manual and automatic operations of
the M series. For the T series, the DAU parameter (bit 4 of parameter No.
3003) can be used to specify whether to make the function usable only for
the manual operation or for both the manual and automatic operations.
NOTE
To enable axis direction–specific interlocking for the
automatic operation of the T series, set the DAU parameter
(bit 4 of parameter No. 3003).
Feeding of all axes can be inhibited only during automatic operation.
When the start lock signal is input while the axes are moving, all axes
decelerate and come to a stop. When the start lock signal is released, the
axes start moving again.
During automatic operation, the start of the next block can be disabled.
A block that has already started is executed as is till its end.
When the block start interlock is released, the execution of the next block
starts.
During automatic operation, the start of a block containing a move
command other than positioning can be disabled.
When the cutting block start interlock is released, the execution of the
next block starts.
When spindle rotation is specified or when the spindle speed is changed,
the cutting block start interlock can be applied until the spindle reaches
a target speed so that the next cutting block can be executed at the target
spindle speed.
