1. Overview
1.2 Differences from Air Cylinders in Control Functions
For those of you who have been using air cylinders and have never used motorized cylinders before, this section
gives a brief explanation of how this controller is different from air cylinders.
Read the following information and implement controls appropriate for your system.
Item Air cylinder ACON
Drive method Air pressure by solenoid valve
control. Ball screw drive using an AC servo motor.
Target position
setting Mechanical stopper (including
shock absorber). Entry of a coordinate value in the “Position” field of
the position table.
A value can be entered by keying in a number from
a PC/teaching pendant, or by moving the actuator
to a desired position and then reading the achieved
position directly.
Example) Example of entry of “400 mm” stroke
Position No. Position
0 5 (mm), rear end
1 400 (mm), front end
2 200 (mm), intermediate point
Target position
detection Installation of a reed switch or other
external detection sensor. Judgment based on internal coordinates
determined by the position information received
from the position detector (encoder).
No external detection sensor is required.
Speed setting Adjustment by a speed controller. Entry of a feed speed in the “Speed” field of the
position table (unit: mm/sec).
Note that the rated speed is set automatically as the
default feed speed.
Acceleration/
deceleration setting In accordance with the load, air
supply volume, and speed
controller/solenoid valve
performance. Entry in the “Acceleration” and “Deceleration” fields
of the position table (minimum setting unit: 0.01 G).
Reference: 1 G = Gravitational acceleration
Note that the rated acceleration and deceleration
are set automatically as the default acceleration
and deceleration.
Desired values can be set in fine steps to achieve
gradual acceleration/deceleration curves.
The greater the set value, the steeper the curve
becomes. On the other hand, the smaller the set
value, the more gradual the curve becomes.
