Notes to cNc interface cable run list
Note 1. I
nputs are optically isolated. They require 24 VDC at 7.3 mA, or dry-contact closure.
The external relay’s life
may be improved by adding a metallized-polyester capacitor (0.022µF 100 V or higher) in parallel with the relay
contacts.
Note 2.
Outputs are optically isolated, open collector, transistors. The maximum rating is 24 VDC at 10 mA.
Note 3. Machine motion is selectable and is used for configurations with multiple plasma systems.
Note 4.*
CNC +24 VDC provides 24 VDC at 200 mA maximum. A jumper is required on J301 to use 24 V power.
* See examples on pages 3-36 and 3-37
caution:
the cNc cable must be constructed using cable with 360 degree shielding and
metal housing connectors at each end. the shielding must be terminated to the
metal housings at each end to ensure proper grounding and to provide the best
shielding.
