3. POSITIONING SIGNALS
3.1.1
Axis status
(1) Positioning start completed signal (M2400+20n)
(a) This signal comes ON when starting of positioning control of the axis
designated by the SVST instruction in the sequence program is completed.
It does not come ON when positioning control starts due to a zeroing, JOG
operation or manual pulse generator operation.
It can be used, for example, to read an M-code when positioning is started.
(See Section 8.2.)
(b) The positioning start completed signal goes OFF at the leading edge
(OFF→ON) of the end signal OFF command (M3204+20n) or when
positioning is completed.
