When the motion command (OW20) is set to 17, the SERVO-
PACK Cn constant data specified in OW35 is stored.
Position Buffer
Read Data
(CNMON)
Position data from the position buffer specified at OL38: Position
Buffer Access Number is read and stored at this parameter when
motion setting parameter OB21F: Position Buffer Read turns ON.
It takes about 2 scans from the time that OB21F: Position Buffer
Read turns ON until data is stored at this register.
