User’s Guide for EM760 series high-performance vector inverter
1
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
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.
