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

Make the following calculation to find the device number corresponding to
each axis.
(Example) M3200+20n (stop command) = M3200+20
×
31=M3820
M3215+20n (servo off)
= M3215+20
×
31=M3835
