# Product Introduction

The ADLINK Nu-Step DA Series is a stepper driver based on the EtherCAT bus featuring a 32-bit ARM processor and advanced variable current and frequency conversion technology. The driver generates less heat and motor vibration for more stable operation. It not only supports the standard EtherCAT specification, but also supports table comparison triggers for automated optical inspection (AOI) and linear comparison triggers for line scanning.

According to the standard EtherCAT specification, various EtherCAT masters can be supported. Compared with traditional communication protocols, EtherCAT offers improved reliability, reduces the influence of noise on instructions and greatly extends communication distance with improved frame error detection and processing.

The Nu-Step DA Series stepper drivers exchange data with a master through an EtherCAT fieldbus that includes motion control commands, feedback, and parameters. With the built-in comparison trigger function, the system meets a variety of process control requirements, including area scanning, line scanning and EMG functions commonly used in AOI.

Through the use of an EtherCAT fieldbus the complexity and difficulty of cable installation between the host controller and the slave can be greatly reduced, saving on cabling and equipment development costs.

In order to meet the diversified process requirements of automation equipment, the Nu-Step DA Series supports the standard EtherCAT fieldbus control mode up to 250 μs cycles. Operation modes include CSP, PP, PV and HM, with programmable positive and negative limits, home and digital input and digital output, which can make more effective use of digital input and output channels on the driver to achieve more accuracy, safety, and faster process procedures.
