V&T Technologies variable frequency drive China for various occasions

◪Operation panel

Chinese/English liquid crystal display keyboard and LED keyboard, abundant information and convenient debugging;

With multi-functional combination key; for example, realize remote/local switching, emergency shutdown and other humanized functions;

Include parameter storage chip, so that the customer is convenient to storage, upload and download the parameters. It is specifically suitable for batch supporting customers, the debugging time is saved greatly; and the installed efficiency is improved.

Support the scheme of extension cord;

◪Strong motor adaptation ability

Be compatible with synchronous motor, asynchronous motor, reluctance motor, electric main shaft and other motors;

Support the open-loop vector of synchronous motor, open-loop vector of asynchronous motor, closed-loop vector of synchronous motor, open-loop vector control of asynchronous motor, etc.

◪Be compatible with the encoders with multiple specifications

Support the photoelectric encoder, rotary transformer encoder and sine and cosine encoder;

Support accessing the motor encoder and auxiliary encoder into the drive at the same time to realize the double-loop control; when ensuring the stability of the control system, the error of the mechanical drive can be eliminated, so the encoder is specifically suitable for the machine tool, bending machine and other industries. For example, the motor encoder is used as the motor speed control; and the auxiliary encoder is used as the position control.

◪Abundant extended function

I/O card can be highly customized according to the demands of the customers;

Support plug and convenient for wiring and maintenance;

I/O terminals with different functions select the design with different colors so as to reduce the probability of error wiring of users greatly; and it is easy to use, beautiful and practical.

◪Book structure, small volume and light weight

Compared with other products of the Company, the volume and weight are reduced by 50%.

The book structure can save the installation space.
