3.1.4 Main Circuit Wiring Requirements The drive power input cable and motor cable can have strong electromagnetic interference. In order to avoid electromagnetic interference through strong interference cables and control circuits generated by long distance parallel wiring coupling. When wiring the main circuit cable and signal cable distance should be greater than 30cm.In addition, common main circuit cables are input RST line, output UVW line, DC bus and brake cables, signal cables are IO signal line, communication line and encoder line. The cables and trunking must be well connected and properly grounded.
Aluminum wireways ensure that the equipment is equipotential, and that filters, drives, and motors should be well lapped to the system (mechanical or device), well protected by spraying in the installed section, and that conductive metals need to be fully contacted.
