Noise reduction techniques
This section provides information on measures that prevent the servo amplifier malfunctioning when it is installed next to
peripheral devices that emit a large amount of noise.
Ground shielded cables close to the servo amplifier. Ensure that the part of the cable before the grounding point does not
induce electromagnetic noise to the section of the cable after the grounding point. Strip part of the shielded cable, then ground
the exposed portion of the cable on a large surface of the cabinet. A metal cable clamp can also be used to ground the cable
(shown below). Mask the painted internal wall of the cabinet that touches the cable clamp.

Ground the both ends of the CN8 cable with the cable clamp. The shield length from the servo amplifier to the cable clamp
should be within 30 cm.
