(2) It is required to realize the proportional intermodal control of multiple units and to automatically adjust the output frequency to keep the speed constant as the load and voltage change.

(3) There must be an RS485 communication function and PLC, and PC to realize communication control.

(4) It is controlled by a common DC bus, and the power-saving effect is good. Inverter products are suitable for use in wire drawing machines. When multiple units are used in proportional linkage, they can be controlled by a common DC bus, and the power-saving effect is better.

Wet Wire Drawing Machine Frequency Converter’s Main Features are as Follows:

(1) Using non-inductive vector control technology, it has the characteristics of low speed and high torque and the characteristic of 0.5HZ up to 150% torque output.

(2) The mechanical ratio design with overspeed operation can improve the starting torque characteristics by 1.5 times.

(3) The proportional linkage of multiple units can be successfully designed to use the DC bus, without adding a braking device, and can be stopped quickly.

(4) The speed accuracy is high, and it has the function of slip compensation. The following takes the modification of a wire drawing machine of a cable company as an example to introduce the characteristics and usage of the frequency converter: When drawing ferrous and non-ferrous metals, the rotation speed of each winch is different, and the synchronous speed can be controlled to prevent pulling. High-speed system communication ensures the control and operation of larger systems.
