* 1. For the wires connected to the casings for installation purposes, use wires with a diameter of 3.5 mm2
or larger. Flat braided copper wires are recommended.
* 2. Use twisted pair wires for section P.
Correct Grounding
• Servomotor frame grounding:
Be sure to connect the FG grounding terminal on the frame of the servomotor to the grounding terminal on the SERVOPACK.
• Be sure to ground the grounding terminal of the SERVOPACK.
• If the wires of the servomotor’s main circuit are laid in a metal conduit, ground the conduit and the
grounding box.
One-point grounding must be used.
