When the FIN signal (M3219+20n) is turned from OFF to ON to OFF during
positioning in block 2), the axis performs constant-speed operation without
decelerating stop in the block of M-code.
(6) The M-codes except the M00, M01, M02, M30, M98, M99 and M100 are output to
the M-code storage registers (D13+20n) of all axes specified at the program start.
However, the M-code storage register is not output to the axis in execution of
high-speed oscillation. Also, if the FIN signal (M3219+20n) is set to the axis in
execution of high-speed oscillation is invalid.
(Program No. 1 is started with X (axis 1) and Y (axis 2) specified
"SVST J1J2 K1" )
