Requirements for EtherCAT
This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with EtherCAT® cables.
- For an example of a system diagram, refer to EtherCAT multi-drop (multi-system) interface (Sheet 17 of 23).
- For information about signals and protocols, refer to EtherCAT communications and Serial RS-422 and EtherCAT commands in the CNC Communication Protocol for the XPR Cutting System (10085793).
- Hypertherm® sells EtherCAT cables that have been tested with our cutting system. Refer to EtherCAT and Ethernet LAN interface cables.
- If you supply your own cables, choose EtherCAT cables that follow the Beckhoff® specification. Refer to Requirements for EtherCAT and Ethernet LAN cables.
- To help prevent problems from Electromagnetic Interference (EMI), make sure
that the EtherCAT cables:
- Have separation from the pilot arc cable, negative cable, or any power cables that have a voltage more than 120 VAC. Refer to Distance requirements between high-frequency cables and control cables.
- Are not near the gas connect console or TorchConnect™ console.
- Hypertherm recommends a minimum distance of one meter (3.3 feet) between the plasma power supply and other system components, or between the plasma power supply and an obstacle.
