CM3+

4. Wiring and Connection

4.1 Typical Connection Example

Caution about cabling

  • Be sure that the power is off before plugging or unplugging connectors.

  • Pay attention to straight insertion and removal of connectors by holding the connector's body.

  • Be sure there is no stress on connectors.

  • Do not pull cables hard or hang CM3+ by holding cables. It may result in damaged connectors.

A typical system connects a PC (via interface cable to the host connector), a +24Vdc power supply (power cable), I/O (I/O cable), and additional CM3+ axes daisy-chained from slave connector to host connector with communication cables.
