4. OPERATION
Choose the servo motor rotation direction at the time when the forward rotation start (ST1) signal or
reverse rotation start (ST2) signal is switched on with parameter No.PA14 (Rotation direction
selection).

Set the unit multiplication factor (STM) of position data with parameter No.PA05 (Feed function
selection).
Parameter No.PA05 setting Feed unit [μm] Position data input range [mm]

3) Operation
Choosing the point table using DI0 to DI7 and turning ST1 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 ST2 ON starts a motion in the reverse rotation direction according to the values set to the selected
point table.
