1-1 Overview of NJ-series Errors
You manage all of the errors that occur on the NJ-series Controller as events. The same methods are
used for all events. This allows you to see what errors have occurred and find corrections for them with
the same methods for the entire range of errors that is managed (i.e., CPU Unit, NX-series Slave Termi-
nals, EtherCAT slaves,* and CJ-series Units).
* Only Sysmac devices are supported. For information on EtherCAT slaves that are Sysmac devices, refer to the
NJ-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505).
You can use the troubleshooting functions of the Sysmac Studio or the Troubleshooter on an NS-series
PT to quickly check for errors that have occurred and find corrections for them.
To perform troubleshooting from an NS-series PT, connect the PT to the built-in EtherNet/IP port on the
CPU Unit.
There are two main types of errors (events) depending on whether the NJ-series Controller can man-
age them or not.
Fatal Errors
These errors are not detected by the event management function of the NJ-series Controller
because the CPU Unit stops operation. You cannot identify or reset these errors with the Sysmac
Studio or an NS-series PT.
Refer to 1-2 Fatal Errors for error types and confirmation methods for fatal errors.
