| Product Characteristics |
| WL-9000 series Frequency Converter is a kind of power converter
which adopts the Sensor-less vector technique and change the
running speed of AC asynchronous motor by controlling the output
voltage and frequency. It can exactly detect the three-phase output
AC signal and the change of phase-angle just by current sensor,and
correct the frequency automatically by the computing mode of
sensor-less vector,so that ensure the motor fixed speed when the
load changing. Compared with V/F Control frequency inverter, WL-9000 Series, not only supply greater torque when motor operating under low-speed, but also compensate auto matically motor rotate-speed change when heavy-load. |
| Product position |
| Bran-new hardware designWL-9000 frequency inverter adopts ARM(32bit
)+ DSP(16bit) Double-CPU control system, to be the bran-new
hardware control platform Current vector controlAdvanced Magnetic-field oriented vector algorithm, to finish motor complete Decouple Control,achieve real current vector control,have advanced V/F mode,less-speed vector control mode and constant power control mode. |
| Whole field protection functions |
| Low voltage protection, over-voltage protection, over-current protection, prevent motorstall, over-load and over-heat protection. |
| Motor parameter Auto-tuning |
| Have Dynamic parameter auto-tuning and Static parameter auto-tuning function, could indentify automatically motor characteristics and auto set parameter, make sure the system’s stability and accuracy. |
| The application of WL-9000 Frequency inverter |
| The real current vector control, make all kinds of mechanical
equipments operate under high efficient and accuracy state. The
sensor-less vector control technology,high torque when motor
low-speed, high speed accuracy, complete functions, could detect
automatically motor dynamic parameter and then do corresponding
regulation,to make sure motor operate under high efficient state. Reduce early-stage cost, and also operating cost because of its energy-saving function,and has reduced the reverse effect to motor and power grid, improve the class of mechanical equipments. |
