[Md.320] Synchronous encoder axis position value
The position value for the synchronous encoder axis is stored in synchronous encoder axis position units (Page 56
Synchronous encoder axis position units).
The synchronous encoder position for an incremental synchronous encoder is "0" immediately after the power supply ON.
[Md.321] Synchronous encoder axis position value per cycle
The position value per cycle for a synchronous encoder axis is stored in the range from 0 to ("[Pr.324] Synchronous encoder
axis length per cycle" - 1).
The unit is synchronous encoder axis position units (Page 56 Synchronous encoder axis position units).
