3-ph VFD High Performance Inverter 4KW/5.5HP

The SINEE EM760L-4R0-3B is a high-performance vector control inverter (Variable Frequency Drive, VFD) designed for industrial automation and machinery. This model is engineered to drive three-phase AC asynchronous motors and permanent magnet synchronous motors, offering advanced control with improved V/F (VVF), sensorless vector (SVC), and speed sensor vector (FVC) technologies. It supports both speed and torque output modes, making it suitable for a wide range of industrial applications.

Key features include robust protection functions such as overvoltage, overload, overcurrent, overheat, and more, ensuring reliable operation in demanding environments. The inverter features an LCD display for easy parameter setting and monitoring, and supports I/O expansion cards, communication bus cards (including Modbus RTU, PROFINET, CANopen, and EtherCAT), and PG cards. The EM760 series offers high torque control accuracy (SVC: ±5% rated torque, FVC: ±3% rated torque), a wide speed regulation range, and a low-frequency carrier (VVF: 3Hz/150%, SVC: 0.25Hz/150%, FVC: 0Hz/180%).
