[Upper System]                                          [Servo Drive COM(CN3) Connector] 
 
 The servo drive has a built-in terminating resistor (120Ω). 
 You can connect terminal resistor by shorting Rt (No.19) terminal and P (No.7)   
      terminal. 
 When connecting several servo drives, be sure to connect the terminating resistor   
      only to the last servo drive.
