1 The device that first sets a process controls the plasma power supply. For information about how to change the device that has
control of the plasma power supply, refer to Change the device that has control on page 197.
2 Discrete inputs are ignored when a process ID is set over EtherCAT to a cutting system that uses the factory-default configuration. If you
have questions, speak to your cutting machine supplier or regional Hypertherm Technical Service team.
Example
If you use EtherCAT to set the process, the preferred method to monitor is EtherCAT. However, you can
use RS-422 or the XPR web interface through Wi-Fi to monitor.
Requirements for EtherCAT
This information prepares you to connect the plasma power supply to the CNC with EtherCAT cables.
■
For an example of a system diagram, refer to EtherCAT multi-drop (multi-system) interface (Sheet 19
of 25) on page 510.
■
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
(809810).
■
Hypertherm sells EtherCAT cables that have been tested with our cutting system. Refer to EtherCAT
CNC interface cables on page 428.
■
If you supply your own cables, choose EtherCAT cables that follow the Beckhoff
®
specification. Refer
to EtherCAT cable specifications on page 156.
■
To help prevent problems from 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 on page 68.
□
Are not near the gas connect console or TorchConnect console.
■
Hypertherm recommends a minimum distance of 1 meter (3.3 feet) between the plasma power supply
and other system components, or between the plasma power supply and an obstacle.
