User’s Guide for EM760 series high-performance vector inverter Preface Thank you for choosing SINEE’s EM760 series high-performance vector inverter. Document No.: 31010200 Release time: 2022-3 Version: 200 The EM760 series inverter is a high-performance vector control inverter launched by SINEE, which integrates the synchronous motor drive and asynchronous motor drive.
It supports three-phase AC asynchronous motors and permanent magnet synchronous motors, internationally advanced drive control technologies [such as the improved vector V/F control technology (VVF), speed sensorless vector control technology (SVC) and speed sensor vector control technology (FVC)], speed output and torque output, Wi-Fi access and background software debugging, expansions (such as I/O expansion cards, communication bus expansion cards and PG cards) . The standard EM 760 supports V/F control, SVC control, FVC control of asynchronous motors; it also supports V/F control and FVC control of permanent magnet synchronous motors.
The non-standard version for synchronous motors also supports V/F control, SVC control, FVC control of asynchronous motors, as well as V/F control, SVC control and FVC control of permanent magnet synchronous motors. The EM760 series high-performance vector inverter has the following features: ⚫ Equipment of a built-in DC reactor (in case of an inverter of above 18.5kW) can reduce input current distortion, increase the power factor and promote the product reliability; ⚫ High torque control accuracy: SVC/±5% rated torque, FVC/±3% rated torque; ⚫ Wide speed range and high control accuracy : SVC/1:200 (±0.2%), FVC/1:1000 (±0.02%) rated speed; ⚫ Low-frequency carrier:
VVF/3Hz/150%, SVC/0.25Hz/150%, FVC/0Hz/180%; ⚫ Protections against overvoltage stall, fast current limit, overload, overheat, off-load, overspeed, and so on; ⚫ Support I/O expansion: 3-channel digital inputs, 2-channel relay outputs, 1-channel -10V~10V voltage input, 1-channel sensor input; ⚫ Support communication bus expansion: standard configuration including 485 bus, optional PROFINET, CANopen and EtherCAT; ⚫ Support various encoders:
ABZ incremental, UVW incremental, UVW wire saver, rotary transformer and ⚫ Support debugging by the mobile phone APP or monitoring of the inverter status; sine-cosine transformer; ⚫ Support Wi-Fi module or serial port access; ⚫ Rich and convenient PC background software functions. Before using the EM760 series high-performance vector inverter, please read this guide carefully and keep it properly. 1
