Speed
Time
(Reference) Acceleration is explained. The same concept applies to deceleration.
1 G = 9800 mm/s 2 : Acceleration at which the actuator can increase its speed up to 9800 mm/s
per second.
0.3 G: Acceleration at which the actuator can increase its speed up to 2940 mm/s (9800 mm/s
× 0.3) per second.
(1) No.
The position data number is shown.
Warning: Be sure to specify absolute coordinates on PCON-C/CG/CF, PCON-CA, ACON-C/CG,
SCON-C, SCON-CA, ROBONET, ERC3 PIO Converter, MSCON (Remote I/O mode)
controllers of solenoid valve mode 2, or PCON-CY and ACON-CY controllers of
solenoid valve mode 1.
If incremental coordinates are specified on these controllers, a position data error
occurs.
Also note that completion of push motion cannot be determined when the push is
specified if incremental coordinates are specified.
(2) Target position [mm]
Enter the target position to move the actuator to.
x Absolute coordinate specification : Enter the target position you want to move the actuator to, based
on the distance from the home. A negative value cannot be
entered.
x Incremental coordinate specification: Enter the target position you want to move the actuator to, based
on the distance from the current position. A negative value can
also be entered.
(Negative direction on displayed coordinate system)
(3) Speed [mm/sec]
Enter the speed at which to move the actuator.
The default value varies depending on the actuator type.
(Note) For SCON-CA, PCON-CA, ERC3 and MSCON, an alarm will be displayed if the set value is lower
than the minimum velocity.
(4) Acceleration/deceleration [G]
Enter the acceleration/deceleration at which to move the actuator.
Basically you should set acceleration/deceleration not exceeding the rated value shown in the catalog.
The input range permits entry of values larger than the rated value shown in the catalog, but this is because
"shorter tact time when the transferring mass is significantly lighter than the rated value" is assumed.
If the load vibrates during acceleration/deceleration to present problems, decrease the value set here.
(Note) For SCON-CA, PCON-CA, ERC3 and MSCON, an alarm will be displayed if the set value exceeds
the rated acceleration/deceleration.
Caution: Acceleration/deceleration setting
(1) Set accelerations/decelerations not exceeding the rated acceleration/deceleration specified in the
catalog or this operation manual. If any acceleration/deceleration is set that exceeds the rated
acceleration/deceleration, the life of the actuator may be significantly reduced.
(2) If the actuator or work part receives impact or generates vibration, lower the acceleration/deceleration.
If the system is used continuously with the actuator or work part receiving impact or generating
vibration, the life of the actuator may be significantly reduced.
(3) If the load transferred by the actuator is significantly lighter than the rated payload capacity, you may
be able to set accelerations/decelerations exceeding the rating. If this is the case, the tact time can be
reduced, so contact IAI. When contacting IAI, tell us the weight, shape and installation method of your
work part and installation condition (horizontal/vertical) of your actuator.
