User Manual of EM760 High-Performance Inverter Preface Thankyou for choosing SINEE’s EM760 series inverter. Document No.: 31010243 Release time: 2023-5 Version: 101 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 sine-cosine transformer; ● Support debugging by the mobile phone APP or monitoring of the inverter status; ● 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. While connecting the inverter to motor for the first time, please select the motor type (asynchronous or synchronous) correctly and set the motor nameplate parameters: rated power, rated voltage, rated current, rated frequency, rated speed, motor connection, rated power factor, etc.
In case of FVC drive control mode, it is required to select the optional PG card and set correct encoder parameters. 1
