Cables for the SGM7J and SGM7A Servomotors
9.2.1
System Configurations
The cables shown below are required to connect a Servomotor to a SERVOPACK.
Encoder Cable of 20 m or Less
Servomotor Main
Circuit Cable
Servomotor
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 SGM7A-15A to SGM7A-30A 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.
• Cable dimensional drawings and cable connection specifications
• Order numbers and specifications of individual connectors for cables
• Order numbers and specifications for wiring materials
Σ
-7-Series Peripheral Device Selection Manual (Manual No.: SIEP S800001 32)
For the following Servomotor models, there are different order numbers for the Servomotor Main
Circuit Cables and Encoder Cables depending on the cable installation direction. Confirm the
order numbers before you order.
