Skip function
This function stops (decelerates to a stop) the positioning being
executed when the skip signal is input, and carries out the next
positioning.
12.7.2
M code output function
This function issues an auxiliary work (clamp or drill stop, tool
change, etc.) according to the code No. (0 to 32767) set for each
positioning data.
12.7.3
Teaching function
This function stores the address positioned with manual control into
the positioning address having the designated positioning data No.
(
Cd.5
).
12.7.4
Command in-position
function
At each automatic deceleration, this function calculates the
remaining distance for the AD75 to reach the positioning stop
position, and when the value is less than the set value, sets the
"command in-position flag".
When using another auxiliary work before ending the control, use
this function as a trigger for the auxiliary work.
