AC servo driver wiring precautions

For signal line and encoder input line, please use shielded wire. Wiring length: the length of signal line from NC to AC servo driver is less than 3m, and the length of input line from AC driver to encoder is less than 20m. The ground wire should be thick wire as far as possible. According to the third grounding standard (grounding resistance < 100 Ω), one point grounding method should be adopted to connect the ground wire. If the motor and the machine tool are insulated, the motor should be grounded.
