Servo feeder because of simple and convenient operation, high precision, operation as long as the touch screen set a good feed. The servo system automatically determines the feed length of each time according to the value set in advance. The operator only needs to see if the machine is working properly without adjusting it every time.

  Servo feederBecause the operation is simple and convenient, high precision, as long as the operation is set on the touch screen feed. The servo system automatically determines the feed length of each time according to the value set in advance. The operator only needs to see if the machine is working properly without adjusting it every time.

PLC control system control automatic feeding action, automatic clamping action and automatic cutting action, the use of the machine can greatly reduce the operator's labor intensity, to provide production efficiency, then the servo feeder servo drive working principle is what.

Because the servo system has the advantages of high precision, high speed, large driving force, complete protection circuit, intuitive fault alarm and so on. already inServo feederThe industry has occupied a dominant position, and in the coastal developed areas, servo feeder has more than 90% of the market share.

The working voltage used by the mainstream servo drive system on the market is two-phase AC 200V, and the drive motor is three-phase AC 200V voltage. Therefore, the control cabinet of the servo feeder will be equipped with a three-phase AC transformer, and 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 servo feeder control system is a pulse direction DC 5V digital signal that can make the servo system work. The internal setting of the servo driver is a position loop control mode. In addition to a four-core power cable, there is also an encoder line from the servo driver to the motor. The main task of this encoder line is to feed back the actual number of turns of the motor and compare the number of turns converted from the pulse command issued by the servo feeder control system, see if it is the same, if it is inconsistent, it will adjust itself to ensure the accuracy of the servo feeder.
