1.This vector control variable frequency drive utilizes advanced SVC vector control and V/F control.
2. In the specifications of 0.75kW to 18.5kW, the product is internally mounted with the brake device in the standard configuration. It supports direct connection with the braking resistor if rapid stop is in need. As for the 160kW and above products, the direct current reactor is equipped in standard configuration to increase the output power factor, eliminating the impact of the high harmonic to the product and reducing the interference to the surroundings.
3. Our vector control variable frequency drive is configured internally with various devices, including the automatic torque compensation system, efficient rotating speed compensation system, PID adjustor and the RS-485 communication port supporting the MODBUS communication protocol.
4. It is able to restart the rotary motor smoothly without any impact by means of torque tracking.
5. This product supports online monitoring and adjustment on multiple parameters.
6. With affluent, flexible input and output interfaces and multiple controls, the product can be combined with diversified equipment in the operation, such as PLC, industrial personal computer or instrument.
7. The LED and LCD operating panels can be selected to accomplish convenient and rapid operation.
8. This vector control variable frequency drive offers pulse input and output, facilitating the digital control in closed loop.
9. It is capable of running at the energy saving mode. Compared with the V/F control system at the same working frequency, this product uses lower current. Moreover, the working voltage can be automatically adjusted, too. If the voltage of the electrical grid starts to change sometime, this product is able to keep the constant output voltage automatically.
10. Designed with totally separated air ductwork, our product offers an optimal dustproof working environment. Additionally, all the plates are plated with conformal coating, presenting perfect protection to the product.
This vector control variable frequency drive is commonly applied in machinery industry about plastics, ceramic, electrics, textile, light industry, pharmaceuticals, packing, printing and dyeing industry, escalator, wire and cable, lathe and grinding machine, bag making, cold rolling machine, low frequency roller table, centrifugal machine, paper making and chemical fiber production lines. As the direct replacement of the AC torque motor, it can be used for controlling the general unwinding or rewinding with constant tension.
