B.2. Wiring for Noise Control
„ Wiring Example
This servo amplifier uses high-speed switching elements in the main
circuit. It may receive “switching noise” from these high-speed switching
elements if wiring or grounding around the servo amplifier is not
appropriate. To prevent this, always wire and ground the servo amplifier
correctly.
This servo amplifier has a built-in microprocessor (CPU). To protect it
from external noise install a noise filter in the appropriate place.
The following is an example of wiring for noise control.

Note: * When using a noise filter, follow the precautions in Using Noise Filters on the following page.
** For ground wires connecting to the casing, use a wire with a thickness of at least 0.005 in 2
(3.5 mm 2 ), preferably a braided flat copper wire.
