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

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

Do not install the product in the case of water in the package or missing or damaged components found in unpacking! 2. Do not install the product in the case of inconsistency between the actual product name and identification on the outer package. 1. When opening the wooden case, do wear gloves; to prevent person injuries, do not contact the sealing plate with hands! 2. When handling the inverter, please hold its bottom. If you hold the front cover, the inverter body may fall down to cause injuries! 3. Handle the controller with care; otherwise, it may be damaged! 4. Never use the inverter damaged or with some parts missing; otherwise, injuries may be caused! 5.

Do not touch components of the control system with your hands; otherwise static charge may be generated to cause damage to the inverter! 6. The inverter has undergone withstand voltage testing before delivery. Do not perform withstand voltage testing on your own; otherwise the inverter may be damaged! During installation: Warning Danger 1. Please install the controller on metal or other flame-retardant objects and keep it away from combustible materials; otherwise, a fire may be caused! 2. Do not loosen the fixing bolts of components, especially those with red marks! Warning 1.

The inverter shall not be installed in a place with conductive dust, corrosive gas, salt spray, oily dirt, condensation, vibration or direct exposure to sunlight! 2. Never allow wire connectors or screws to fall into the inverter; otherwise, the inverter may be damaged! 3. When the inverter is installed a relatively closed cabinet or space, pay attention to the installation gap to ensure the effects of heat dissipation. During wiring: Danger 1. Observe the instructions in this manual and make wiring done by professional electrical personnel; otherwise, electric shock may be caused! 2.

The inverter must be separated from the power supply by using a circuit breaker (it is recommended to use a circuit breaker of greater rated current that is the most approximate to twice the rated current of the inverter); otherwise, a fire may be caused! 3

User’s Guide for EM760 series high-performance vector inverter 3. Before wiring, make sure that the power supply is OFF (zero energy). Do not carry out wiring when the controller is powered on; otherwise, electric shock may be caused! 4. Never connect the input power supply to the output terminals (U, V, W) of the inverter. Pay attention to the marks of wiring terminals, and connect wires correctly! Otherwise, the inverter may be damaged and even a fire may be caused! 5. Ground the controller correctly and reliably as required; otherwise, electric shock may be caused! 1. Connect the output terminals (U, V, W) of the inverter to corresponding input terminals (U, V, W) of the motor.

An inconsistent phase sequence will cause the motor to reverse. 2. 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! 3. Never connect the braking resistor directly between the DC bus and the terminal; otherwise the inverter may be damaged and a fire may be caused! 4. Use a screwdriver with the specified torque to tighten main circuit terminals; otherwise, a fire may occur! 5. Never connect the phase-shifting capacitor and LC/RC noise filter to the output circuit. 6. Do not connect the electromagnetic switch and electromagnetic contactor to the output circuit.

Otherwise, the overcurrent protection circuit of the inverter will be enabled, and internal damage of the inverter may be incurred in severe cases. 7. Do not dismantle the connecting cable inside the inverter; otherwise, internal damage may be caused to the inverter. Before power-on: Warning Danger 1. Check whether the supply voltage is consistent with the rated voltage of the inverter; otherwise, equipment damage or fire may be incurred. 2. Check whether wiring of power input terminals (R, S and T) and output terminals (U, V and W) is connected correctly; 3.

Check whether there is a short circuit among the peripheral circuits connected to the inverter and whether all connected lines are tightened; otherwise, the inverter may be damaged! 1. The inverter must not be powered on until it is properly covered; otherwise, electric shock may be caused! 2. The wiring of all peripheral accessories must be in line 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! Warning After power-on: 1. Never touch the inverter and surrounding circuits; otherwise, electric shock may occur! 2.

If the indicator does not turn on or the keyboard does not display after electrification, immediately turn off the power switch; 10 minutes later, check if the wiring is connected properly. Do not touch the inverter terminals R, S and T and any power terminal by hand or with a screwdriver; otherwise, electric shock may occur! After eliminating the causes of wiring errors, contact our customer service personnel immediately. 3. Never touch any wiring terminals of the inverter after electrification; otherwise, electric shock may occur! 4. Do not disassemble any parts of the inverter while it is powered on. Danger 1.

If parameter identification is required, please pay attention to the danger of injury caused by the rotating motor. Check the safety before parameter identification; otherwise, an accident may be caused! 2. Do not change the parameters set by the inverter manufacturer without permission; otherwise, the inverter may be damaged! Warning During maintenance: Danger 4
