Product Advantages and Features
1.Translation: High reliability and stability
Adopting industrial-grade components, it supports a wide temperature operating environment of -25℃~+60℃, can resist complex working conditions such as dust and vibration, and has a mean time between failures (MTBF) of more than 100,000 hours to ensure the continuous operation of industrial production lines.
2.Translation: Precise control and efficient performance
Compared with similar stepper control modules, its 32x microstep subdivision technology can achieve higher positioning accuracy. Equipped with distributed clock synchronization function, the multi-axis control error is <1μs, which can meet scenarios with strict precision requirements such as precision machining and automated assembly.
3.Translation: Flexible expansion and strong compatibility
Supporting daisy-chain topology, a single EtherCAT master station can control a large number of modules in series to easily expand the system scale; at the same time, it is compatible with mainstream industrial protocols such as EtherCAT and OPC UA, and can seamlessly connect with upper-level systems such as MES and ERP, adapting to the Industry 4.0 smart factory architecture.
4.Cost and energy consumption optimization
As a stepper control solution, the hardware cost is reduced by about 30% compared with the traditional servo system, and the dynamic current adjustment technology reduces the standby power consumption to 0.2W, which can significantly reduce the enterprise's energy consumption and operation and maintenance costs in long-term use.
5.Dual-channel stepper motor control
Equipped with 2 independent control interfaces, supporting two control signal modes of pulse/direction (PULSE/DIR) and CW/CCW. Each channel has a peak output current of 5A, which can drive 42~86 type stepper motors to meet the needs of multi-axis independent motion control.

Product Application Scope
Automated Assembly Lines for Electronic Components:
In chip packaging equipment and connector insertion production lines, it is responsible for driving the stepper motors of material conveying rails and component grabbing robotic arms. Through the dual-channel independent control function, it can synchronously realize the whole process of "material conveying - precise grabbing - positioning assembly". Combined with high-speed data transmission (100μs single-frame cycle), it increases the assembly beat to 3-5 times per second, meeting the high-efficiency mass production needs of the 3C industry.
Precision CNC Machining Equipment:
Suitable for five-axis linkage milling machines, small machining centers and other equipment, used to control the stepper motors for spindle feeding and workbench displacement. With multi-axis synchronization error <1μs and positioning accuracy of ±0.01mm, it can accurately perform milling, drilling and other processes for complex parts, ensuring the dimensional tolerance and surface finish of machined parts, and meeting the high-precision manufacturing needs of aerospace, automotive parts and other fields.
