Acromag has recently expanded its BusWork NT series with the introduction of the NT2710 module. This module is a stepper motor controller that enables remote motion control via Ethernet protocols, including PROFINET, EtherNet/IP, and Modbus/TCP. The NT2710 can work with various control systems, including PCs, PACs, and PLCs. It is designed to offer precise motion control and native IIoT capabilities alongside modular I/O expansion options.

The NT2710 Stepper Motor Controller
Acromag's new NT2710 stepper motor controller module offers six outputs for pulse trains, which work to control the step and direction signals of stepper motor drivers. Additionally, it includes six encoder inputs, allowing for enhanced flexibility in motion profiling and control over the motor's speed, direction, and position.
Users can program the control module with triangular, linear, or trapezoidal acceleration/deceleration profiles to perform a range of motion tasks, ensuring smooth motion with minimal mechanical stress. The new module also has functions for motion control, such as a high-resolution timer, and features four general-purpose I/O channels that can be used for basic control.

Multi-Protocol Communication
The NT2710 module supports multi-protocol communication, enabling seamless integration with existing control systems via Ethernet/IP, Modbus/TCP, and PROFINET. These protocols, accessible through any standard web browser, offer flexibility in terms of communication options for sending commands to the stepper motor control. Additionally, the new module supports advanced IIoT capabilities through MQTT client, OPC UA server, and RESTful API.
The NT2710 module, with its multi-protocol capabilities, enables seamless remote control, facilitating secure cloud-based data exchange and monitoring. A built-in conditional logic allows the creation of custom rules through the web using IF/THEN/ELSE logic, without requiring complex programming, and defines up to 64 logic conditions per module.

Expandable and Modular Architecture
With the NTE Ethernet and NTX models, the new NT2710 can be expanded through an isolated RS-485 bus. This feature allows users to connect up to three NTX expansion modules using a DIN rail-mounted bus linked to one NTE Ethernet communication module. This NT architecture allows adding up to 64 extra I/O channels using a single Ethernet IP address. The configuration can be used for analog signal control and monitoring, switching and sensing, and temperature measurement capabilities, including PTD inputs and thermocouples.
These models also support direct data sharing between devices using Acromag's i2o peer-to-peer and multicast messaging technology, enabling decentralized remote control without needing a master control.
When it comes to design, the new controller model is engineered to withstand a wide temperature range of -40 °C to 70 °C and features CE compliance. A removable terminal block simplifies wiring. The NT2710 features 1500 V isolation between power and I/O networks for safety and reliability.
Stepper Motor Control
As the trend of incorporating innovative IIoT capabilities and Industry 4.0-ready solutions continues to grow, options like the NT2710 appear as potential future-ready solutions for motion-centric applications. Acromag's new solution offers native IIoT connectivity, modular expansion capabilities, and multi-protocol Ethernet support. It seeks to provide a scalable solution for industries seeking a standalone control system for their integrated manufacturing applications.
