Selecting Cables

Cable Configurations
The cables shown below are required to connect a Servo Motor to a SERVOPACK.
Note: 1. If the cable length exceeds 20 m, be sure to use a Relay Encoder Cable.
2. If you use a Servo Motor Main Circuit Cable that exceeds 20 m, the intermittent duty zone in the torque-motor
speed characteristics will become smaller because the voltage drop increases.
3. Refer to the following manual for the following information.
• Cable dimensional drawings and cable connection specifications
• Order numbers and specifications of individual connectors for cables
• Order numbers and specifications for wiring materials
