Wiring diagram
The typical wiring diagram of the servo system is as follows.
The driver can provide a +5V, maximum power supply of 80mA to the encoder. By using the four-fold frequency counting method, the resolution of the encoder multiplied by four is the number of pulses per turn of the servo motor.

Note: When VCC is 5V, R is shorted;
When VCC is 12V, R is 1K, which is greater than 0.125W.
When VCC is 24V, R is 2K, which is greater than 0.125W.
The resistor must be connected to the control signal
