SI-485/J Ser. Comm. Interf. RS485

Why Choose the Yaskawa SI-485/J RS-485 Communication Option?

The Yaskawa SI-485/J is a dedicated RS-485 communication option card designed to enable reliable serial communication between compatible Yaskawa inverter drives and external automation systems. The module allows drives to exchange commands, status information and operational data with PLCs, HMIs and industrial control networks through an RS-485 interface.

Designed for integration with Yaskawa J1000 series inverter drives, the SI-485/J enables connection to industrial communication systems using common serial protocols such as MEMOBUS / Modbus. This allows engineers to monitor drive performance, adjust parameters and control motor operation remotely from supervisory control systems.

The option module installs directly into the drive’s internal option slot, allowing quick implementation of communication capabilities without complex wiring or external interface devices. This provides a simple method for integrating inverter drives into industrial automation networks and machine control systems.

Industrial Drive Communication and Networking

Industrial automation systems commonly require inverter drives to communicate with PLCs, industrial computers and supervisory control systems. Communication modules such as the SI-485/J allow drives to exchange operational data and control commands over an RS-485 serial network.

Using RS-485 communication, multiple drives can be integrated into a networked control system where parameters, alarms and operating data can be monitored remotely. This enables improved diagnostics, centralised system management and efficient commissioning of industrial drive installations.

Typical Applications

• Integration of inverter drives with PLC control systems.
• Industrial drive monitoring through SCADA or automation software.
• Remote parameter configuration and diagnostics.
• Machine automation and production equipment.
• Industrial motor control networks using Modbus communication.
