Preface
Thank you for choosing SINEE’s EM730/EM730E series inverter.
Document No.: 31010183
Release time: June 2020
Version: 100
The EM730/EM730E series inverter is a high-reliable and small-sized universal inverter
launched by SINEE. EM730 supports three-phase AC asynchronous motors, while EM730E
supports permanent magnet synchronous motors. They support a variety of drive control
technologies, such as the vector VF (VVF) control and speed sensorless vector control (SVC);
speed output and torque output; and Wi-Fi access and background software debugging.
Features of the EM730/EM730E series inverter:
 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;
 No need for derating at the ambient temperature of 50 ℃;
 Support “one-key shuttle” for fast and accurate speed adjustment;
 Perfect protections: Protections against the short circuit, overcurrent, overvoltage,
overload, overheating, etc.
Before using the EM730/EM730E series inverter, please read this manual 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.
