This document describes the connection methods and parameter settings for Delta controllers and various brand devices. It includes default values and communication rates for Delta frequency converters, servo drives, PLCs, and temperature controllers. It also provides detailed instructions on the wiring methods between different models of human-machine interfaces and controllers.
The Delta Controller ASCII/RTU manual describes the supported communication ports and wiring for RS‑232, RS‑422 and RS‑485 connections. It lists the pin assignments for each 9‑pin D‑sub connector and the default communication parameters for both ASCII and RTU modes.
The document also contains the complete register map used by the controller, including servo, inverter, temperature‑control and PLC registers. Each register entry shows the word address, data length and description, enabling integration with external devices and programming of the controller. This manual is written in Japanese.
| ASCII communication speed | 9600, 7, None, 2 |
|---|---|
| RTU communication speed | 9600, 8, None, 2 |
| RS‑232 connector type | 9 pin D‑sub male |
| RS‑422 connector type | 9 pin D‑sub male |
| RS‑485 connector type | 9 pin D‑sub male |
The controller supports both ASCII and RTU protocols over RS‑232, RS‑422 and RS‑485 interfaces.
The default ASCII mode parameters are 9600 baud, 7 data bits, no parity, 2 stop bits.
The RS‑485 connector uses a 9‑pin D‑sub male connector.
