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

Safety precautions

User Manual of EM760 High-Performance Inverter Safety precautions Safety definition: Safety precautions are divided into the following two categories in this manual: Danger: The dangers caused by nonconforming operations may include serious injuries and even deaths. Note: The danger caused by nonconforming operations, including moderate or minor injuries and equipment damage. During the installation, commissioning and maintenance, please read this chapter carefully, and follow the safety precautions herein. Our company will not be liable for any injury or loss arising from nonconforming operations. Precautions Before installation: Δ Danger 1.

Do not install the product in the case of water in the package or missing or damaged components found in unpacking! Do not install the product in the case of inconsistency between the actual product name and identification on the outer package. 2. Attention 1. Handle the controller with care; otherwise, it maybe damaged! 2. Never use the inverter damaged or with some parts missing; otherwise, injuries maybe caused! 3. Do not touch the components of the control system with your hands; otherwise, there is a danger of static damage! During installation: Δ Danger 1. Please install the inverter on a metal retardant object (e.g.

metal) and keep it away from combustibles; otherwise, a fire maybe caused! Do not loosen the fixing bolts of components, especially those with red marks! 2. 1. Never make wire connectors or screws fall into the inverter; otherwise, the inverter maybe damaged! 2. Install the inverter in a place with little vibration and exposure to direct sunlight. 3. When the inverter is installed a relatively closed cabinet or space, pay attention to the installation gap to ensure the effects ofheat dissipation. Attention 3

Safety precautions

User Manual of EM760 High-Performance Inverter During wiring: Δ Danger 1. Follow the instructions in this manual, and appoint professional and electrical engineering personnel to complete wiring; otherwise, unexpected dangers maybe caused! 2. The inverter and power supply must be separated by a circuit breaker (recommendation: greater than or equal to and closest to twice the rated current); otherwise, a fire maybe caused! 3. Before wiring,make sure that the power supply is in the zero energy status; otherwise, electric shock maybe caused! 4. Never connect the input power supply to the output terminals (U, V, W) of the inverter.

Pay attention to the marks ofwiring terminals, and connect wires correctly! Otherwise, the inverter maybe damaged! 5. Make the inverter grounded correctly and reliably according to the standards; otherwise, electric shock and fire maybe caused! Attention 1. Make sure that the lines meet the EMC requirements and local safety standards. For wire diameters, refer to the recommendations. Otherwise, an accident may occur! 2. Never connect the braking resistor directly between the DC bus and terminal. Otherwise, a fire may be caused! 3. Tighten the terminals with a screwdriver of specified torque; otherwise, there is a risk of fire. 4.

Never connect the phase-shifting capacitor and LC/RC noise filter to the output circuit. 5. Do not connect the electromagnetic switch and electromagnetic contactor to the output circuit. Otherwise, the overcurrent protection circuit of the inverter will be enabled. In severe cases, the inverter maybe subject to internal damage. 6. Do not dismantle the connecting cable inside the inverter; otherwise, internal damage maybe caused to the inverter. Before power-on: Δ Danger 1. Make sure that the voltage level ofthe input power supply is consistent with the rated voltage ofthe inverter; and the input terminals (R, S, T) and output terminals (U, V, W) of the power supply are connected correctly.

Check whether there is short circuit in the peripheral circuits connected to the inverter and whether all connecting lines are tightened; otherwise, the inverter maybe damaged! The withstand voltage test has been performed to all parts ofthe inverter, so it is not necessary to carry it out again. Otherwise, an accident maybe caused! 2. Attention 1. 2. The inverter must not be powered on until it is properly covered; otherwise, electric shock maybe caused! The wiring of all peripheral accessories must be inline with the instructions in this manual. All wires should be connected correctly according to the circuit connections in this manual. Otherwise, an accident may occur! 4
