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 EM
C 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.
