5.1 Description of Position-Data Table
(1) No.
 Indicate the position data number.
To enter an incremental movement, press the minus key in this column.
On the teaching pendant, a “=” will be displayed between the number and
position columns.
The minus key need not be pressed in the absolute mode.
(2) Target position (Position)
 Enter the target position to move the actuator to, in [mm].
Absolute mode: Enter the distance to the target actuator position from the
home.
Incremental mode: Enter the distance to the target actuator position from the
current position. A negative value can also be entered (for
movement in the negative direction along the displayed
coordinate axis).
No. Position
0 30 Absolute mode 30 mm from the home
1 10 Incremental mode +10 mm from the current position
2 -10 Incremental mode -10 mm from the current position
3 100 Absolute mode 100 mm from the home
(3) Speed (Speed)
 Enter the speed at which the actuator will be moved, in [mm/sec].
The default value varies depending on the actuator type.
(4) Acceleration/deceleration
(ACC)
 Enter the acceleration/deceleration at which the actuator will be moved, in [G].
Use the rated acceleration specified in the catalog, as a rule.
This product can be used at higher accelerations to shorten the takt time, but
only if the actual use conditions are such that the “load is significantly more
than the rating.”
To support the above function, the acceleration field in the position table
accepts values greater than the rated acceleration.
Note: Enter appropriate values for speed and acceleration/deceleration by referring to 1.3, “Specifications”
and considering the installation conditions and shape of the load, to make sure the actuator will not
receive excessive impact or vibration.
Whether or not the values of speed and acceleration/deceleration should be raised has a lot to do
with the transferring mass and how the actuator characteristics will change also varies depending on
the model. Consult IAI’s Sales Engineering Section for the maximum values of speed and
acceleration/deceleration you can enter.
