Cables for the SGM7G Servomotors
9.3.1
System Configurations
The cables shown below are required to connect a Servomotor to a SERVOPACK.
Note: 1. Cables with connectors on both ends that are compliant with an IP67 protective structure and European
Safety Standards are not available from Yaskawa for the SGM7G Servomotors. You must make such a
cable yourself. Use the Connectors specified by Yaskawa for these Servomotors. (These Connectors are
compliant with the standards.) Yaskawa does not specify what wiring materials to use.
2. If the cable length exceeds 20 m, be sure to use a Relay Encoder Cable.
3. 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.
4. Refer to the following manual for the following information.
