Noise Filters
You must attach Noise Filters in appropriate places to protect the SERVOPACK from the
adverse effects of noise. The following is an example of wiring for countermeasures against
noise.
*1. For the ground wire, use a wire with a thickness of at least 2.0 mm
2
(preferably, flat braided copper wire).
*2. Whenever possible, use twisted-pair wires to wire all connections marked with .
