The EM760 series inverter is a high-performance vector control inverter launched by SINEE, which integrates the synchronous motor drive and asynchronous motor drive. It supports three-phase AC asynchronous motors and permanent magnet synchronous motors; drive control technologies, such as the improved vector VF control technology (VVF), speed sensorless vector control technology (SVC) and speed sensor vector control technology (FVC); speed output and torque output; Wi-Fi access and background software debugging; expansions such as I/O expansion cards, communication bus expansion cards and PG cards.

Features of the EM760 series Frequency Converter:
1.Standard built-in C3 filter to meet the high requirements of electromagnetic compatibility
2.Built-in DC reactor to reduce input current distortion and increase the power factor
3.Standard LCD panel, easy to operate
4.Integration of the permanent magnet synchronous motor / asynchronous motor / permanent magnet
synchronous reluctance motor / high-speed motor drive
5.Mainstream bus expansion cards: PROFINET, CANopen, EtherCAT
6.PG cards: OC, differential, UVW, resolver PG card, sine and cosine PG card
