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 PCON
Drive method Air pressure by solenoid valve control. Ball screw or timing belt drive using a pulse 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.
