[Md.141]BUSY
This signal turns ON at the start of positioning. It turns OFF when the "[Da.9] Dwell time/JUMP destination positioning data
No." has passed after positioning stops. (This signal remains ON during positioning.) This signal turns OFF at error
completion or positioning stop.
The BUSY signal turns ON even when position control of movement amount 0 is executed. However, since
the ON time is short, the ON status may not to be detected in the program.
[Md.345] Command generation axis accumulative position value
The accumulative position value for the command generation axis is stored in the "[Pr.1] Unit setting". The axis whose unit
setting is other than "degree" is set to "command position value = accumulative position value".
[Md.347] Command generation axis position value per cycle
The position value per cycle for the command generation axis is stored in the range from 0 to ("[Pr.346] Command generation
axis length per cycle" - 1).
