Checking for Fatal Errors

You can identify fatal errors in the NY-series Controller based on the status of the PWR, RUN and ERR
indicators, the monitor display, as well as by the possibility to go online from the Sysmac Studio. Refer
to Section 2 Error Troubleshooting Methods for information on identifying errors and corrections.

*1 An online connection to the Sysmac Studio is necessary to differentiate between CPU Unit Resets, CPU Unit
Errors, and non-fatal errors in the NY-series Controller. For an OS Startup Error, an error message is displayed
on the monitor screen. Power Supply Errors and System Initialization Errors can be differentiated with the in-
dicators. There is no need to see if you can go online with the NY-series Controller from the Sysmac Studio.
