Foreword
Thank you for choosing Megmeet MV820 series high-performance vector control drive.
As a new-generation vector control platform, MV820 adopts an advanced drive solution, which integrates synchronous
motor drive and asynchronous motor drive, torque control and speed control, and possesses leading drive indicators,
able to meet various needs that require high performance. Meanwhile, MV820 has sound anti-trip control and strong
adaptation to harsh environments with bad power mains, high temperature, high humidity or filled with dust, largely
improving the reliability.
MV820 provides modular expansion, enabling you to add modules flexibly based on your special needs. Besides, MV820
has advanced VF, SVC and FVC for speed and torque control, closed-loop process control, multi-function input and
output terminals, pulse frequency reference, simple PLC, main/auxiliary reference control, master-slave control and so
on, fully capable for various drive scenarios, lowering system costs and improving system reliability.
MV820 is designed with overall electromagnetic compatibility and optimized PWM control, meeting environmental
requirements for low noise and low electromagnetic interference.
This manual mainly consists of installation, wiring, parameter setting, fault diagnosis, trouble shooting, daily
maintenance and related matters. Please read this manual carefully before you install and use the drive so as to release
the drive’s full potential, keep the manual properly and give it to the actual user when necessary.
