The VB series high-performance frequency inverters use the international mainstream 32-bit DSP as the main control chip. It has fast calculation speed, high control accuracy, and powerful control performance. Using well-known brand power devices and raw materials, processed with advanced manufacturing technology to meet the high-quality needs of our customers.

Maximum Output Frequency Improved

SVC Control Mode: Maximum Output Frequency 320Hz

VF Control Mode: Maximum Output Frequency 1000Hz

A maximum output frequency of 1000Hz in VF control mode can meet 

various speed control demands from customers Flow Chart of GND Short-circuit Detection

Excellent Braking Function

【Over-excitation Braking Function】 

The over-excitation braking function can help with a prompt braking action even without the braking unit on some occasions.

【Dynamic Braking Function】 

The braking torque could be higher and braking time shorter if working with a braking resistor. 

The 0.75-22KW models are designed with built-in braking units.

(Remarks) The braking performance varies from motor characteristics and load conditions.

Superior Control Performance

The improved low frequency and high torque quick- starting performance brings a faster response speed and a higher production efficiency The probability 

of equipment failure and shutdown can be reduced effectively with the enhanced current suppression algorithmso as to ensure a more stable processing capacity of the equipment.

Random Carrier Function

【Noise Reduction】

The random carrier function helps reduce the noise of the equipment so as to improve the environmental comfort.

Motor GND Short-Circuit Detection

The motor GND short-circuit detection function makes sure that the equipment is operating under normal andsafe conditions thus improving the safety coefficient.
