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 MainDevice can be supported. Compared with traditional
communication protocols, EtherCAT offers improved reliability, reduces the influence of noise on instructions and greatly extends
the communication distance with improved frame error detection and processing.
The Nu-Step DA Series stepper drivers exchange data with a MainDevice through an EtherCAT field bus 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
field bus the complexity and difficulty of cable installation between the host controller and the SubDevice 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 field bus control mode up to 250μs 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.
