CAUTION
1. Use Environment
PCON controllers can be used in an environment corresponding to pollution degree 2 or equivalent.
2. PC Software and Teaching Pendant Models
New functions have been added to the entire PCON controller series.
To support these new features, the communication protocol has been changed to the general Modbus
(Modbus-compliant) mode. As a result, the existing PC software programs and teaching pendants compatible
with RCP2 controllers can no longer be used.
If you are using this controller, use a compatible PC software program and/or teaching pendant selected from the
following models.
skrameRledoM
PC software (with RS232C
communication cable) RCM-101-MW
PC software (with USB communication
cable) RCM-101-USB
Teaching pendant RCM-T
Simple teaching pendant RCM-E
Data setting unit RCM-P
All are compatible with existing RCP2
controllers.
3. Recommendation for Backing Up Latest Data
This product uses nonvolatile memory to store the position table and parameters. Normally the memory will retain
the stored data even after the power is disconnected. However, the data may be lost if the nonvolatile memory
becomes faulty.
We strongly recommend that the latest position table and parameter data be backed up so that the data can be
restored quickly when the controller must be replaced for a given reason.
The data can be backed up using the following methods:
[1] Save to a CD or FD from the PC software.
[2] Create a position table sheet or parameter sheet and keep a written record of backup.

4. Using Rotary Actuators in Multi-rotation Specification
Rotary actuators of multi-rotation specification models can be set to operate in the multi-rotation mode or
limited-rotation mode using a parameter.
4.1 Note
Pay attention to the PIO pattern parameter setting for the following controllers.
Each controller does not support relative coordinate specification in the PIO pattern specified below:
[1] PCON-C/CG: PIO pattern = 5 (User parameter No. 25)
[2] PCON-CY: PIO pattern = 0 (User parameter No. 25)

1.1 Introduction
As a dedicated controller for our RCP2 and RCP3 actuators, this controller becomes smaller and more affordable and
incorporates a new set of features to offer greater convenience and safety, while maintaining the functions of the RCP2
controller.
This controller also provides power-saving functions to address the growing need for saving energy.
The key features and functions of this controller are summarized below.
zLimited I/O positioning points (3 points)
The I/O signals are designed to function in the same manner as those of air cylinders. Two operation types are supported.
The movement complete signals have different meanings in each type.
•Proximity switch type --- Each movement complete signal works as an auto switch. Even when positioning operation is
not performed, a movement complete signal is output once the specified position is passed.
•Standard type --- A movement complete signal is output only when positioning operation has completed following
a move command.
* The controller is configured to support the proximity switch type before shipment.
zSeparate zone output limits for each of 3 positions (rear end, intermediate point, front end)
Before, the zone output limits were set by parameters and thus fixed to a certain width for all positions. To increase
flexibility, setting fields have been added to the position table to allow different limits to be set for each position.
This function is useful in preventing contact with peripheral equipment or reducing the tact time.
zIndependent acceleration and deceleration settings
The position table now has separate fields for acceleration and deceleration.
The purpose of this change is to prevent works made of certain materials or having certain shapes from receiving impact or
vibration when the actuator decelerates to a stop.
By reducing the deceleration setting, a more gradual deceleration curve can be achieved.
zLimitation of feed speed during adjustment by test operation
The feed speed during adjustment by test operation can be limited to ensure safety.
zPower-saving measures
In general, pulse motors consume more holding current in standstill state than AC servo motors. Accordingly, this controller
provides power-saving means by assuming situations where the motor is used in applications requiring a long standby
time.
When actually starting your system or if you have encountered any problem, also refer to the manuals for the actuator,
teaching pendant, PC software and/or any other component you are using, in addition to this manual.
This manual does not cover all possible deviations from normal operations or unexpected phenomena such as complex
signal changes resulting from critical timings.
Therefore, the reader should assume that items not described in this manual are “not permitted,” as a rule.
* This manual has been prepared with the utmost attention to ensure accuracy and completeness. However, there may still
be inaccuracies and omissions. Should you find any inaccurate description or if you have any comment, please contact
IAI.
Keep this manual in a convenient place so that you can easily reference it whenever necessary.

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.
