13-3 Checking for Errors and Trouble-
shooting on the Sysmac Studio
Error management on the NX Series is based on the methods used for the NJ-series Controllers.
This allows you to use the Sysmac Studio to check the meanings of errors and troubleshooting proce-
dures.
When an error occurs, you can place the Sysmac Studio online to the Controller or the EtherCAT Cou-
pler Unit to check current Controller errors and the log of past Controller errors.
The methods that are used to check errors depend on the Controller you use.
Refer to the NJ-series Troubleshooting Manual (Cat. No. W503) for information on NJ-series error man-
agement methods.
Refer to the NJ-Series Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for details on trou-
bleshooting with the Sysmac Studio.
If you cannot check the error on the Sysmac Studio, check the error by following the flow outlined in
13-10 Troubleshooting Flow When Errors Occur on page 13-51.
Additional Information

You can use an NS-series PT to view current errors on the EtherCAT Coupler Unit errors and
