The servo feeder is simple and convenient to operate and has high precision. As long as the feed amount is set on the touch screen during operation, the servo system automatically determines the feed length of each time according to the value set in advance. The operator only needs to watch whether the machine is working normally without adjustment every time. The PLC system controls automatic feed action, automatic clamping action and automatic cutting action. The use of this machine can greatly reduce the labor intensity of operators and improve production efficiency. So what is the working principle of the servo feeder servo drive? The following editor will analyze for you.

Due to the advantages of high precision, high speed, large driving force, complete protection circuit and intuitive fault alarm, the servo system has always been in a dominant position in the servo feeder industry. In the developed coastal areas, servo servo feeder already has more than 90% market share.

The mainstream servo drive system on the market now uses a two-phase AC 200V working voltage, while the drive motor is a three-phase AC 200V voltage. Therefore, the servo feeder control cabinet will be equipped with a three-phase AC transformer. The power of the transformer depends entirely on the total power of the servo used. Therefore, the control cabinet of the servo feeder uses the three-phase four-wire working voltage of the external network.

The command mode issued by the control system of the NC servo feeder is a pulse direction DC 5V digital signal that allows the servo system to work, and the internal setting of the servo driver is the position loop control mode. In addition to the four-core power cord from the servo drive to the motor, there is also an encoder cable. The main task of this encoder line is to feed back the actual number of turns of the motor and the number of turns calculated by the pulse command issued by the servo feeder control system to see if they are the same. If it is inconsistent, it will automatically adjust to ensureServo feederAccuracy of operation.
