## Autonics' Closed-Loop Stepper Motor System for Precise Position Control

Autonics has introduced the AiC-MT series, a high-torque and high-precision stepper motor system. This system combines the precise positioning capability of servo systems with the high holding torque of stepper motors.

The AiC-MT series provides control for up to 254 axes via the Modbus TCP protocol. The system is equipped with an integrated controller and encoder, offering support for closed-loop control. Furthermore, features typically found in a servo system have been integrated into this stepper motor system.

### AiC-MT System Features

• Comes with an integrated controller and encoder
• Configuration and position control via Modbus TCP communication protocol
• Supports daisy-chain connection for up to 254 axes
• Standard motor control signals: start, stop, direction, in-position, and alarm
• Motor parameters can be set via field data or with the Windows-based "atMotion" software
• Available in 6 different frame sizes, from 20 mm to 60 mm
• Optional gearbox for 42 mm and 56 mm frame sizes
• Operates with a 24 VDC power supply, consuming 240 W during operation and 15 W in holding state
• High holding torque that prevents automatic position hunting

While position deviation and position hunting are common issues under load in typical servo systems, the high holding torque of the AiC-MT eliminates this problem. The use of an encoder provides real-time position verification, preventing potential deviations or alarm conditions.

### Closed-Loop Control System

Unlike open-loop systems which lack a feedback mechanism, closed-loop systems continuously monitor the motor's position via an encoder. This minimizes position errors even in high-speed applications.

### Application Areas

Stepper motors can be preferred in many areas where servo motors are used. They are an ideal solution in places where three-phase AC power is unavailable or in systems requiring stable and precise positioning. Especially in image processing applications like camera positioning, clear and stable positioning is crucial. The AiC-MT system, with its integrated encoder and high-speed processor, offers a reliable positioning solution for such applications.
