Usually, the feedback signal of the pulse encoder of the servo motor needs to be connected to the encoder interface of the servo amplifier. This interface is usually a standard digital input interface, which can accept the digital signal output by the encoder. On the interface, the servo amplifier will decode the signal output by the encoder and convert it into the position and speed information of the motor.
It should be noted that different servo motors and servo amplifiers may have different interface types and interfaces. Therefore, it is necessary to carefully check the instructions of the motor and amplifier when wiring to ensure the correct connection of the feedback signal of the encoder. In addition, it is necessary to pay attention to the resolution and signal type of the encoder to ensure that the servo system can accurately control the rotation of the motor.
