Variable Frequency Inverter Vvvf - Chinaprice: contact company for price
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.
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)
