It works with 3-3.5 kW three-phase motors to provide precise position, speed, and torque control. With features like Modbus RTU support, 8 digital inputs, 7 digital outputs, 2 analog inputs, and brake control, it is suitable for a wide range of automation applications. It ensures reliability with built-in protection functions.
GSSJ-H4 SERVO DRIVER
With advanced microprocessor and semiconductor technology, servo systems consisting of permanent magnet motors are becoming more economical, and are increasingly used in automation systems for applications requiring precise measurement, high and stable speed control, torque control, rapid acceleration, and deceleration.
Our servo systems, offered to the machine manufacturing industry, are commonly used in machines such as test devices, presses, cutting, filling, packaging, plastics, food, textiles, CNC, woodworking, etc.
