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,
improving power factor and enhancing reliability of the product;
High torque control precision: SVC/±8% rated torque;
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:
485 bus, Profibus-DP network, CANopen network and DeviceNet network;
Support special function expansion: constant pressure water supply and so on.
Please read this manual carefully before using EM500 and keep it properly.
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,
