ABB FMBA-01 Modbus RTU adapter module ACS355 series inverter

The ABB FMBA-01 is a Modbus RTU adapter module designed for the ACS355 series inverter. Here is a detailed introduction:

Function and Application

Communication Function: It enables the connection of the drive to an RS - 485 Modbus - RTU network, facilitating efficient data exchange between the inverter and other devices in the industrial automation system. It supports common read/write single and multiple register function codes, allowing for flexible access to and control of inverter parameters.

Application Scenarios: It is mainly used in industrial automation scenarios where centralized monitoring and control of inverters are required. It allows operators to monitor and adjust the operating status of the inverter through the Modbus-RTU network, improving the efficiency and reliability of the entire system.

Technical Specifications

Communication Interface: It adopts the RS - 485 interface, which has strong anti - interference ability and can ensure the stability and reliability of communication signals. It supports the Modbus - RTU communication protocol, which is widely used in the field of industrial automation and has good compatibility.

Power Supply: It usually obtains power from the inverter, and the power supply voltage range is consistent with that of the inverter, generally 24 VDC ± 10% or 110 - 230 VAC ± 10%. This allows for flexible installation in different power supply environments.

Dimensions: The dimensions of the module are 11×1×1 cm, which is compact and easy to install in the inverter cabinet, saving valuable space.

Installation and Use

Mechanical Installation: The FMBA-01 is installed in the ACS355 series inverter. First, remove the relevant cover of the inverter, and then install the adapter module in the designated position and fix it with screws.

Electrical Installation: Connect the RS-485 communication cable to the corresponding terminal of the FMBA - 01 module, and then connect it to other devices on the Modbus - RTU network according to the wiring requirements of the network. Pay attention to the correct connection of the positive and negative poles of the communication cable to avoid communication failures.
