1. Overview
1.1 Introduction
This product is a pulse-train input controller used exclusively with RCP2 actuators.
It can control actuators using the positioning control function of the host controller (PLC).
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.
„ Dedicated Homing Signal
This signal supports IAI’s original homing operation based on push motion at the stroke end.
With this signal, homing can be performed automatically without having to program a complex sequence or using
an external sensor, etc.
„ Brake Control Function
The electromagnetic brake power is supplied internally from the controller. However, 24 V must be supplied
externally to forcibly release the brake when the servo is off.
„ Torque Limiting Function
This controller lets you limit torque using an external signal (set by a parameter). A signal is output when the
specified torque is reached. This function enables push-motion operation, press-fit operation, etc.
„ Full Servo Control Function
The holding current can be reduced via servo-control of the pulse motor.
Although the exact level of current reduction varies in accordance with the actuator type and load condition,
normally the holding current drops to approx. one-half to one-fourth.
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.
