1.2. System Connections and Noise Prevention DCS810S Digital DC Servo Driver Manual Rev1 0 After finishing the above steps you can connect your servo system Before you start make sure that the power is off Connect your system according to connection diagrams before and pay attention to the following tips when wiring Wire Gauge The smaller wire diameter lower gauge the higher impedance Higher impedance wire will broadcast more noise than lower impedance wire Therefore when selecting the wire gauge it is preferable to select lower gauge 1 e larger diameter wire This recommendation becomes more critical as the cable length increases Use the following table to select the appropriate wire size to use in your application Current A Minimum wire size AWG 10 20 15 18 20 16 Cable Routing All content sensitive signal wires should be routed as far away from motor power wires and driver power wires as possible Motor power and driver power wires are major sources of noise and can easily corrupt a nearby signal This issue becomes increasingly important with longer motor power and driver power wires lengths Twisted Wires Twisted wires effectively increasing noise immunity The successive twists eliminate noise transients along the length of the cable Both signal cables and power cables should be of the twisted and shielded type Differential signal wires should be twisted as a pair The combination of twisted pair wires
