3) Feed length multiplication selection (parameter No.PA05)
Set the unit multiplication factor (STM) of position data.
Parameter No.PA05 setting Feed unit [μm] Position data input range [mm]
0 1 0 to 999.999
1 10 0 to 9999.99

(c) Operation
Choosing the point table using RYnA to RYnE, RY(n
2)3 to RY(n 2)5 and turning RYn1 ON starts a
motion in the forward rotation direction over the moving distance of the position data at the preset speed
and acceleration time constant.
Turning RYn2 ON starts a motion in the reverse rotation direction according to the values set to the
selected point table.
