Preface

EM500 Open-Loop Vector Control Inverter User Manual Preface Thank you for purchasing EM500 series inverter. Document No.: 31010076 Issue Date: 2018-07 Version: 103 EM500 inverter is an open-loop vector control inverter that supports: 3-phase AC induction motor and permanent magnet synchronous motor; multiple internationally leading drive control technologies, including improved vectored VF control technology (VVF) and sensorless vector control technology (SVC); speed and torque control; I/O expansion card, communication bus expansion card and special function expansion card.

EM500 dedicates to any application, so it can be applied to nearly all open-loop control applications, for example fan, water pump (water supply under constant pressure), air compressor, winding and unwinding function, and direct wire-drawing machine. For high-precision closed loop application, please select EM600. Main features:  Built-in DC reactor starting from 11kW, reducing input current distortion,  High torque control precision: SVC/±8% rated torque; improving power factor and enhancing reliability of the product;  Wide speed regulation range and high control precision: VF/1:50, SVC/1:200 and ±0.2% rated speed;  Loading capacity at low frequency:

VF/1Hz/150% and SVC/0.25Hz/150%;  Multiple types of guarantees: Overvoltage stall, rapid current limit, overload protection, overheating protection, off-load protection, overspeed protection, etc.;  Support I/O expansion: 4 numeric inputs, 1 numeric output, and one -10V - 10V voltage input;  Support communication bus expansion and realize various industrial networking:  Support special function expansion: constant pressure water supply and so on. Please read this manual carefully before using EM500 and keep it properly.

485 bus, Profibus-DP network, CANopen network and DeviceNet network; Before connecting inverter and a motor for the first time, please select proper motor type (induction motor or synchronous motor) and configure motor nameplate parameters including rated power, rated voltage, rated current, rated frequency, rated rotation speed, motor connection and rated power factor. Since SINEE is committed to the development and improvement of products and product documents, this manual will be updated without notice.

During Installation:

EM500 Open-Loop Vector Control Inverter User Manual Safety Information In this manual, there are two types of safety information. Danger: The label indicates that a failure to follow instructions can result in serious injury or even death. Caution: The label indicates that a failure to follow instructions can result in moderate or slight injury and device damage. Please read this chapter carefully before system installation, debugging and maintenance and always follow the safety precautions below during operation. SINEE will not undertake any damage or loss caused by a failure to follow the instructions. Safety Precautions Before Installation: Danger 1.

Do not install inverter if its package is wetted or any its component is missing or broken. 2. Do not install inverter if the label information on its package is not identical to that on inverter. Caution 1. Be careful when carrying or transporting inverter so as to avoid damage! 2. Do not use inverter if it is damaged or any component is missing so as to avoid injury! 3. Do not touch the parts of control system with bare hands so as to avoid ESD! During Installation: Danger 2

Wiring:

EM500 Open-Loop Vector Control Inverter User Manual 1. Installation base shall be metal or other non-flammable material so as to prevent fire risk. 2. Do not unscrew fixing bolts, especially bolts with red mark. Caution 1. Ensure that no cable strips or screws are dropped into inverter so as to avoid damage to inverter. 2. Install inverter at a place with less vibration and no direct sunlight. 3. Consider the installation space for cooling purpose when inverter is installed in a closed cabinet or space. Wiring: Danger Wiring must be performed by authorized and qualified personnel so as to avoid unexpected accidents.

A circuit breaker must be installed between inverter and the mains so as to prevent fire risk. Ensure that power is off before wiring, and ground inverter in accordance with the applicable wiring standard so as to avoid electric shock. Grounding terminal must be grounded reliably so as to avoid electric shock and fire risk. Danger Never connect input power supply cable to output terminals U, V or W of inverter. Pay attention to terminal symbols and connect to the terminals correctly so as to prevent risks of damaging inverter. Be sure that wiring meets EMC requirements and local safety standards. Cable should be in recommended sizes so as to prevent accident risk.

Do not connect braking resistor to DC bus terminals + and – so as to prevent fire risk. Tighten terminals with a screwdriver of specified torque so as to prevent fire risk. Do not connect a phase-shifting capacitor or an LC/RC noise filter to output circuits. Do not connect a solenoid switch or an electromagnetic contactor to output circuits. Otherwise, it will trigger the action of the overcurrent protection circuit or even damage the internal parts of inverter. Do not disconnect internal cable of inverter, or else this can possibly damage the internal parts of inverter. Caution 1. Ensure the distribution lines accord to EMC requirements and the local area's safety standards.

The using wire size refers to the preferred recommendation. Otherwise, an accident may occur! 3

After Power-on:

EM500 Open-Loop Vector Control Inverter User Manual 2. Never connect the braking resistor directly between the DC bus and the terminals. Otherwise cause a fire! 3. Tighten the terminal with the specified torque screwdriver, otherwise there is the danger of fire. 4. Do not connect the phase-shift capacitor LC / RC noise filter to the output circuit 5. Do not connect the electromagnetic switch or electromagnetic contactor to the output circuit. Otherwise, the inverter over-current protection circuit is activated when severe, can cause damage to the inverter. 6. Do not disassemble the connecting cable inside the inverter. Otherwise, the inverter may be damaged. Before Power-on:

Danger Verify that input voltage is identical to the rated voltage of inverter, input terminals R, S and T and output terminals U, V or W are correctly connected, there are no short circuit phenomena for the wiring of inverter and its peripheral circuits, and all wires are in good connection. Otherwise, this may result in inverter damage. Never perform voltage withstanding test on inverter, because it has been done at the factory. Otherwise, this may result in accident. Caution The front cover of inverter must be closed before inverter is powered on. Otherwise, it may result in an electric shock. The wiring of all peripherals must be conducted in accordance with the guidance of this manual.

Otherwise, it may result in an electric hazard. After Power-on: Danger 1. Do not touch inverter or its peripheral circuits with wet hands to avoid the electric shock. 2. If the indicator is off or the keypad does not display any information after power-on, please cut off the power supply immediately. Never touch any terminal of R, S or T of inverter or the connecting terminals with hands or a screw driver, or else an electric shock accident may occur. Contact our customer service personnel immediately after cutting off the 4
