6. Data Entry
Warning
x If the actuator contacts the work part before reaching the target position, a servo error
alarm will generate. Pay due attention to the relationship of the target position and the
work part position.
x The actuator continues to push the work part at the push force at standstill determined
by the current-limiting value. Since the actuator is not inactive, exercise due caution
when handling the equipment in this condition.
(2) Torque check function when a check band is not used
After reaching the target position set in the “Position” field of the position table, the actuator moves at the push
speed by the distance set in the “Positioning band” field. If the command torque reaches the threshold before the
end of the positioning band is reached, the load output will turn ON. The load output will turn OFF once the
command torque drops to below the threshold.
„ The push speed is set by parameter No. 34, “Push speed.”
The factory setting varies with each actuator in accordance with the characteristics of the actuator.
Set an appropriate speed by considering the material and shape of the work part, among others.
Take note, however, that the maximum speed is limited to 10 mm/s.
„ Set parameter No. 51, “Torque check range” to “1 [Disable].”
„ Set a desired threshold in the “Threshold” field of the position table (input range: a desired value within the
specified push force range).
„ Set a desired positioning band in the “Positioning band” field of the position table.
Set a positioning band slightly longer than the last position, in order to absorb possible mechanical variation
of the work part.
For details, refer to Chapter 8, “Parameter Settings.”

The load output turns ON inside this range.
The position complete signal turns ON here,
as completion of push action is recognized
after the load has been contacted.
