Servo motor power cable (1)
If stripping the cable outer sheath will affect the safety of the machine such as electric shock or injury, it is recommended to
install additional protective covers or enclosures.
Shielded cable
Metal conduit
1.
Use four shielded cables (3-phase + ground cable) to prevent disconnection outside the cabinet. Connect the grounding
terminals of the servo amplifier and servo motor with the grounding cable.
2.
Ground the shield on both the cabinet side and servo motor chassis side. For the reason why the shield should be
grounded on both the cabinet side and servo motor chassis side, refer to the following.
Page 28 Reason for grounding the shield on both the cabinet side and servo motor chassis side
The grounding position of the shield on the servo amplifier side should be within 10 cm from the cabinet. For the reason why
the grounding position of the shield on the servo amplifier side should be within 10 cm from the cabinet, refer to the following.
