4. Description of Operating Functions
(4) Acceleration/deceleration: Enter the acceleration/deceleration at which the actuator will be moved, in [G].
Basically, use acceleration/deceleration within the catalog rated value range.
The input range allows larger value input than the catalog rated values, on the assumption that the tact time
will be reduced if the transfer mass is significantly smaller than the rated value.
Make the numeric value smaller if transfer work vibrates and causes trouble during
acceleration/deceleration.
The acceleration will become sudden if the numeric value is made larger, and it will become gradual if the
numeric value is made smaller.
Caution: Enter appropriate values for the speed and acceleration/deceleration in such a way as to
prevent excessive impact or vibration from being applied to the actuator in consideration of
the installation conditions and the shape of transferred work by referring to the “List of
Actuator Specifications” in the Appendix.
Increasing such values largely relates to the transfer mass and the actuator characteristics
vary depending on the model, consult IAI regarding the input-limiting values.
(5) Push: Select the positioning operation or push & hold operation.
The default value is “0.”
0: Normal positioning operation
Other than 0: Indicates the current-limiting value and indicates the push & hold operation.
(6) Threshold: This field is invalid in the case of this controller.
The default value is “0.”
(7) Positioning band: The “positioning operation” and “push & hold operation” have different implications.
Positioning operation
It defines the distance to the target position from a
position at which the position complete signal turns
ON.
Since increasing the positioning band value hastens
the next sequence operation, it becomes a factor for
tact time reduction. Set the optimum value by
considering a balance of the entire equipment.
