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.
