Part 1 Specification

(4) Acceleration/Deceleration x Input the acceleration/deceleration at which to move the actuator (unit: [G]). Input a value

within the rated range.

(Refer to Appendix, “Specification List of Supported Actuators.”)

Exercise caution when setting the acceleration/deceleration, because the input range is

greater than the rated range in the catalog.

If the transferring load vibrates during acceleration/deceleration to cause problems,

decrease the set value.

Increasing the value will make the acceleration/deceleration curve sharper, while

decreasing the value will make the curve more gradual.

Caution

Refer to Appendix, “Specification List of Supported Actuators” and input appropriate values for speed and

acceleration/deceleration by considering the installation conditions and the shape of the transferring load, so that the

actuator will not receive excessive impact or vibration.

Take note that increasing this value will significantly affect the allowable transferring mass, or may even cause a system

failure.

(5) Push

x

Select “positioning operation” or “push operation.”

The factory setting is “0.”

0:

Normal positioning operation

Other than 0: The set value indicates a current-limiting value. The push operation mode is

selected when a current-limiting value is set.

(6) Threshold

x

This field is not used with this controller.

The factory setting is “0.”

(7) Positioning Band

x

How the set value is handled varies between “positioning operation” and “push operation.”

“Positioning operation”

This field defines how much before the target

position the position complete signal is

turned ON.

Even after the position complete signal turns

ON, the actuator will continue to move toward

the target position.

Increasing the positioning band will quicken

the start of the next sequence, which helps

reduce the tact time. Set an optimal value by

considering the balance of the entire system.
