Preface

Thank you for purchasing VD520 Series Inverters!

VD520 is a high-performance vector control inverter developed by VicRuns. Adopting advanced

vector control algorithm, it is widely used for asynchronous motor speed control. Through its

integrated EMC design and with optimized PWM control technique to meet users’ demand on

environmental requirement such as low-noise in application places and low EMI. It has perfect

anti-tripping control and good adaptive ability to bad power grid, temperature, humidity and dust, in

order to satisfy various sophisticated requirement under high precision drive applications, thus to

satisfy users expectation of higher reliability and stronger adaptability to environment of their

equipment, achieving industry specialization and personalized motor drive and control system

solution.

VD520 series high performance vector control inverter has following outstanding features:

1. Various control method

Supporting control method: SVC, V/F control.

2. Leading vector control algorithm

Optimized sensorless vector control has better low speed stability, stronger low frequency load

capacity, supporting speed control and torque control.

3. Support multi-function I/O extension and multi-function MFI extension port

Multi-function I/O extension card, multi-function MFI extension port can connect related extension

function unit defined by manufacturer.
