NACHI BUY222伺服放大器单元 英文资料：
NACHI BUY222 servo amplifier unit
NACHI BUY222 is a specialized servo amplifier unit designed by NACHI-FUJIKOSHI for electro-hydraulic servo systems. It is mainly used to drive servo valves and achieve high-precision closed-loop control of hydraulic systems. It is commonly used in heavy industrial equipment such as robots, machine tools, injection molding machines, and presses. This model has been discontinued, but it is still widely used in existing equipment.
1、 Core positioning and functions
Electro hydraulic servo drive: receives ± 10V command signal, compares and amplifies it with feedback signal, outputs control current, drives servo valve torque motor, and accurately controls valve core opening.
Closed loop control core: Built in signal conditioning, PID operation, and limiting protection, forming a complete closed loop to ensure the position/speed/pressure accuracy of the hydraulic actuator.
Wide voltage power supply: supports AC 200-220V input and is compatible with industrial site power grids.
Adjustable current output: The output current range is ± 10- ± 100mA, compatible with most NACHI and MOOG series servo valves.
Multiple protections: Built in overcurrent, short circuit, overheating, and maximum current limiting to prevent damage to servo valves and amplifiers.
High response bandwidth: Typical bandwidth of 1200Hz, meeting the requirements of high-speed dynamic control.
Feedback interface: Supports feedback input from displacement/pressure sensors to achieve full closed-loop control.
Status indication: Onboard LED displays power, operation, and alarm status for easy on-site diagnosis.
Industrial grade reliability: wide temperature range, anti vibration, EMC protection, suitable for harsh environments in workshops.
Modular structure: Independent unit design, easy to install, debug, and ｒｅｐｌａｃｅ, reducing maintenance difficulty.
Compatible models: mostly used for NACHI SA160 series robots and heavy-duty hydraulic equipment.
Weight: Approximately 11.79kg (26lbs), sturdy structure.
Application scenarios: robot joint control, machine tool hydraulic axis, injection molding machine locking/injection molding, precision press fitting of press machines, etc.
