Troubleshooting for invalid processes

Diagnostic code 716

Diagnostic code 716 occurs when there is a problem with the cut process sent to the Computer Numerical Control (CNC). There are six different smart-fault data values that you can get with a 716 code. The troubleshooting steps are different for the different values. When you get a 716 code, make sure that you identify the smart-fault value before you send a process change.

For an overview of the troubleshooting process for the 716 code, refer to Troubleshooting flowchart for diagnostic code 716.

716

The operator-selected process is not supported by this plasma cutting system.

There are six smart-fault data values for the 716 code:
  • 1: invalid id
  • 2: invalid user
  • 3: invalid user source
  • 4: invalid process
  • 5: not allowed or system not ready
  • 6: not supported
 All models None
  • Set process
  • Remote on-off

1: invalid id

The process ID is equal to zero (0).

Select a process ID for the application. Refer to the XPR Cut Charts Instruction Manual (809830).

2: invalid user

Another interface has control of the cutting system.

Only one communication method at a time can send a process ID to the plasma cutting system. The communication methods are:
  • Serial
  • EtherCAT®
  • Wireless

3: invalid user source

Another interface has control of the cutting system.

Only one wireless interface at a time can send a process ID to the plasma cutting system.

Select or change the interface that has control of the plasma cutting system. Refer to Change the device that has control.

If the CNC has control and you change control to another device using the RESET OPERATOR button in the XPR web interface, you can get a 716 code if you try to send a process from the CNC. If this occurs, select RESET OPERATOR again on the same device as before to give control back to the CNC. In some conditions, it can also be necessary to set the line-disconnect switch to OFF and then back to ON.

4: invalid process

An incorrect process ID was sent.

Select the correct process ID for the application. Refer to the XPR Cut Charts Instruction Manual (809830).

5: not allowed or system not ready

The cutting system is not prepared for a new process ID. It can only accept a process ID during the following states:
  • Initial Checks state (2)
  • Inert Gas Purge state (4)
  • Wait for Start state (5)
  • Manual Leak Test state (20)
  • End of Cycle state (14)
  1. Wait until gas purge is complete or until cutting is complete.

    The plasma cutting system cannot accept a new process ID during gas purge or cutting.

  2. If you cannot find or correct the problem, speak to your cutting machine supplier or regional Hypertherm® Technical Service team.

6: not supported

The different gas connect consoles have different capabilities. For example, argon assist and argon marking for mild steel are available for cutting systems installed with OptiMix™, VWI™, or CorePlus™ gas connect consoles, but not with Core™.

Select a process that aligns with the gas connect console and the type of cutting that you are trying to do. Refer to:
