J J Wiring Example
This Servopack uses high-speed switching elements in the main circuit. It may receive "switch-
ing noise" from these high-speed switching elements if wiring or grounding around the Servo-
pack is not appropriate. To prevent this, always wire and ground the Servopack correctly.
This Servopack has a built-in microprocessor (CPU), so it is necessary to protect it from external
noise as much as possible by installing a noise filter in the appropriate place.
The following is an example of wiring for noise control.

2. For wires indicated by P , use twisted-pair wires whenever possible.
3. When using a noise filter, follow the precautions in J Using Noise Filters.
