Variable Frequency Inverter Vvvf - China

B900 series current vector frequency inverters are widely used for elevator/lift/crane/hoist application.

Which adopt 100% pure yaskawa G5/VS616 technology and software, the performance are not inferior at all with yaskawa G5/VS616 - now many lift/elevator customers use our B900 series frequency inverter to replace Yaskawa G5/VS616 frequency inverter.

Our B900 series main features as below:

· 32bit DSP microprocessor configuration

· Magnetic field oriented flux vector control

· Auto-tune ability

· Available for speed-type servo controller while PG feedback added

· RS-232/RS-485 serial communication port

· Capacities from 1HP - 1200HP

· Optional DC reactor available (for reducing harmonic interference from the power supply)

· Multi-language large screen LCD displays the drive status in six languages and a parameter copy mode function.

· English

· Chinese

· Russian

· German

· French

· Spanish

Any type of machine starts smoothly at low speeds

B900 features full-scale flux vector current control that directly controls motor torque based on present control theory utilizing a magnetic flux observer and neuron-control.

It features full torque control even at zero speed when PG option is added.

Four controls in one device; the ultimate device for all applications

Four control methods are included:

· Standard V/F control

· V/F control with PG feedback

· Sensorless flux vector control

· Flux vector current control with PG feedback

Simply select the parameters, B900 can be applied to a wide range of applications from servo-like precision machinery to multiple motor drives.

Factory presets default to sensorless vector control type, but it can be configured to the V/F control mode for applications requiring multiple motors on one device, or set to flux vector current control mode (with PG) for highly precise vector operation.

(PG interface card is optional)
