Part 1 Installation
Data input methods Teaching pendant or PC software
Absolute brake unit (brake
type or absolute
specification actuator only)
Built-in brake drive circuit
Driven by over-excitation at 90 V, released at 45 V (steady state)
There are no limitation on the number of brake axes (A 6-axis system with
all axes equipped with a brake can be supported.)
Protective functions Motor overcurrent, overload, motor driver temperature check, overload
check, encoder open detection
Regenerative resistance
Built-in (1 k  , 20 W); expandable by external unit
Accessory I/O flat cable
Standard inputs 32 points or 16 points, NPN or PNP (set before shipment)
Standard outputs 16 points or 32 points, NPN or PNP (set before shipment)
RS232C port for teaching
serial interface
Enabled only in the manual operation mode.
IAI’s dedicated teaching pendant or ANSI teaching pendant (selected by a
switch)
RS232C port for general
PC connection
Dedicated 2 channel RS232C, 9 pin DTE specification
Half-duplex at speeds up to 115.2 kbps (1 channel) or up to 76.8 kbps
(simultaneous communication with 2 channels)
Note 3)
Expanded inputs/outputs
(optional)
Expandable to 3 slots
Fieldbus interface (optional) Profibus-DP (IN: 32 bytes max./OUT: 32 bytes max.)
DeviceNet (IN: 32 bytes max./OUT: 32 bytes max.)
CC-Link (IN: 32 bytes max./OUT: 32 bytes max.)
Ethernet interface (optional) Packet communication (client-server communication) by TCP/IP using SEL
language
X-SEL PC software connection
MODBUS/TCP remote I/O (IN: 32 bytes max./OUT: 32 bytes max.)
Note 1) The voltage protection rating of the actuator motor is 1000 V for 1 minute.
When performing a voltage test with the controller and actuator connected, make sure the test voltage and
duration will not exceed 1000 V and 1 minute, respectively.
Note 2) If one RS232C channel is used at a communication speed of 115.2 kbps, use the other channel at 38.4
kbps or below. If these speeds are exceeded, an overrun error or other problems will occur and successful
communication cannot be guaranteed.
* RCS2-R**7, LS and LSA-series actuators cannot be connected as axis 5 or 6.
1.3 Differences between QX Type (Global Specification) and PX Type (Standard Specification)
Users require different safety categories in accordance with the overall configuration of their equipment.
The QX type (global specification) controller has no built-in drive source cutoff circuit so that the user can
design their equipment to a desired safety category. The PX type (standard specification) controller has a
built-in circuit for cutting off the drive source inside the controller using a relay. The differences between
these two specifications are summarized below. Items not specified in the table are basically the same
between the two specifications.
Differences between Global Specification and Standard Specification
