The ACC-24E2A 4-AXIS is a highly integrated servo interface expansion board designed primarily for advanced motion control systems, such as those using Delta Tau’s UMAC or MACRO Station controllers. It provides four servo amplifier channels supporting analog, pulse-and-direction, and digital pulse-width modulation (PWM) command outputs, making it versatile for controlling multiple servo or stepper axes in industrial automation.
This module is used where precise, synchronized control of multiple servo motors is required, such as multi-axis CNC machining, robotics, and complex packaging machinery. It supports various feedback types, including differential quadrature encoders, analog sinusoidal encoders, and SSI absolute encoders, facilitating robust position and speed monitoring. The board can be expanded with option cards to increase functionality or change output signal formats, enabling custom-tailored motion solutions.
