Appendix 4 - 6

Power cable for servo motor

Power cable for spindle motor

[1] Use four wires (3-phase + earthing) for the power cable that are completely shielded and free from 

breaks.

[2] Earth the shield on both the control panel side and motor chassis side.

[3] Earth the shield with a metal P clip or U clip. 

(A cable clamp fitting can be used depending on the wire size.)

[4] Directly earth the shield. Do not solder the braided shield onto a wire and earth the end of the wire.

[5] When not using a shield cable for the power cable, use a conventional cabtyre cable. Use a metal 

conduit outside the cable.

[6] Earth the power cable on the control panel side at the contact surface of the conduit connector and 

control panel. (Mask the side wall of the control panel with paint.)

[7] Follow the treatment shown in the example for the conduit connector to earth the power cable on the 

motor side. (Example: Use a clamp fitting, etc.)
