Cable Configurations
The cables shown below are required to connect a Servo Motor to a SERVOPACK.
Note: 1. Cables with connectors on both ends that are compliant with an IP67 protective structure and European Safety
2. If the cable length exceeds 20 m, be sure to use a Relay Encoder Cable.
3. 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.
4. 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

For the following Servo Motor models, there are different order numbers for the Servo Motor
Main Circuit Cables and Encoder Cables depending on the cable installation direction. Confirm
the order numbers before you order.
