These cables are specially designed for CNC applications, and are perfect for connecting our pre-configured motors to the Gecko G540. Standard DB9 cables use small conductors that are completely inappropriate for motor applications, as they are not rated to carry the required current, resulting in excessive heat and power-starved motors. A standard 30 AWG cable will have over an Ohm of resistance in each conductor in a 12 foot length, potentially wasting over 15 Watts of power for a 3.5 Amp/Phase motor. They also have rigid PVC jackets that crack over time as they are bent back and forth.
Our top quality 6 conductor cables use 20 AWG wire with only 0.1 Ohms of resistance per conductor. They feature strain relieved, overmolded connectors in a highly flexible jacket for cool-running, trouble-free power delivery to your motors. Run them through cable trays or other conduit, and rest-assured they will last through many motion cycles. They are configured to pass the phases and the current set resistor in our motors through to the G540. Building a larger machine and need more than 12 feet? Plug two together to get the cable length you need!
See the difference in our cables in the product pictures. The red cable is the CNC Router Parts cable, while the grey one is a standard serial cable. This isn’t a “Monster Cable” sales pitch — both you and your machine will be able to tell the difference.
