This document describes the procedures for connecting Oriental Motor Brushless Motor and
Driver Package BLE Series FLEX RS-485 communication type (hereinafter referred to as
Driver) to CJ-series Programmable Controller + Serial Communications Unit (hereinafter
referred to as PLC) using serial communications and for checking their connections.
Refer to Section 6. Serial Communications Settings and Section 7. Serial Communications
Connection Procedure to understand setting methods and key points to send / receive
messages using the serial communications.
The ladder program in a prepared CX-Programmer project file is used to check the serial
connection by sending or receiving the messages of reading ''Direct I/O and electromagnetic
brake status'' to/from Driver.

This document aims to explain wiring methods and communications settings
necessary to connect corresponding devices and to provide setting procedures.
The program used in this document is designed to check if the connections are
properly established, and is not designed to be constantly used at a site.
Therefore, functionalities and performances are not sufficiently taken into
consideration.
When you construct an actual system, please use the wiring methods,
communications settings and setting procedures described in this document as
a reference and design a new program according to your application needs.
