How to connect to the plasma power supply with EtherCAT
For an example of a system diagram, refer to EtherCAT multi-system interface (Sheet 16 of
22) on page 422.
For information on signals and protocols, refer to EtherCAT communications and Serial
RS-422 and EtherCAT commands in the CNC Communication Protocol for the XPR
Cutting System (809810).
Figure 38 – EtherCAT cable
Hypertherm sells EtherCAT cables that have been tested with our cutting
system. Refer to EtherCAT CNC interface cable on page 387. in the Parts
List.
If you supply your own cables, choose EtherCAT cables that follow the Beckhoff
®
specification.
Use the following recommendations to avoid electromagnetic interference (EMI) problems with your
cutting system:
Separate the EtherCAT cable from the pilot arc lead, negative lead, or any power cables that
have a voltage higher than 120 VAC. Refer to Distance requirements between
high-frequency leads and control cables on page 63.
Do not putthe EtherCAT cable near the gas connect console.
