Selecting Cables
3.4.1
Cable Configurations
The cables shown below are required to connect a Servomotor to a SERVOPACK.
Note: 1. If the Encoder Cable length exceeds 20 m, be sure to use a Relay Encoder Cable.
2. If you use a Servomotor 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

Servomotor Main Circuit Cables
*
Use Flexible Cables for moving parts of machines, such as robots. The recommended bending radius (R) is 90
mm or larger.
Note: Direct Drive Servomotors are not available with holding brakes.
