How Servo Motors Work
The "switch" of Fuji PLC is used to control the start and stop of the servo controller. The start or stop of the servo controller is to start and stop the servo motor. The control accuracy of the servo controller is higher than that of the inverter.
Servo motors are generally used in occasions requiring high control accuracy (such as: speed control, position control, torque control). Fuji servo motor comes with photoelectric encoder. The rotation of the rotor drives the code disc of the photoelectric encoder. The number of turns of the rotor directly affects the number of pulses sent by the encoder to the controller. The pulses make the servo rotate, and the DO output determines the servo direction. The pulse direction controls the direction of the servo, the forward pulse servo rotates forward, and the reverse pulse servo reverses, so the Fuji servo motor combined with the servo controller can truly realize its precision control.
If the servo is controlled by analog quantity, positive and negative analog quantity can be used for forward and reverse control.
If using communication control, send the command directly. On the program, you can directly input the position JOG command to make it forward or reverse.
