1. Overview
1.1 Introduction
Thank you for purchasing the RCS controller. This manual explains the features and operating procedures of the
product.
If not used or handled properly, any product cannot fully demonstrate its function or may cause an unexpected
breakdown or end its life prematurely. Please read this manual carefully and handle the product with utmost care
while ensuring its correct operation. Keep this manual in a convenient place so the relevant sections can be
referenced readily when necessary.
If you are also using any of IAI’s various actuators and/or optional PC software or teaching pendant, also refer to
the operation manual for each item.
 Actuator duty
It is recommended that IAI’s actuators be used at a duty of 50% or below as a guideline in view of the
relationship of service life and accuracy.
Duty is calculated by the formula below:
Duty (%) =
hours operating - Non hours Operating
hours Operating

x 100
 Controller version
A label on which a serial number is printed is attached on the right side of the controller.
The last two digits of the serial number, consisting of an alphabet and a number, indicate the version of your
controller.
Example) SERIAL No. ET352720 N5
In this example, the controller version is “N5.”
When the controller is updated to a higher version, the alphabet will change to a higher letter and the number
will increase. Take note that some controller specifications will vary depending on the version.
 The absolute RCS controller is able to perform positioning operation immediately after the power has
been input and an absolute reset performed. You need not perform home return every time the
power is reconnected. Other basic functions are the same as those of the standard RCS controller.
 The absolute RCS controller is shipped without an absolute reset executed. It must be done by the
user.
Only RCS actuators of absolute specification can be used with the absolute RCS controller. It cannot
be used with RCS actuators of incremental specification.
 Notes on installing the absolute-data backup battery
Be sure to follow the installation steps below to initialize the battery circuit and thereby prevent an
early consumption of the battery:
[1] Connect the encoder cable.
[2] Turn on the power.
[3] Install the absolute-data backup battery.
The above steps must always be followed when the encoder cable has been disconnected for
relocation, etc.
