You can check the sources and causes of the errors in the system-defined variables or from the Sys-
mac Studio or an NS-series PT.
Classifications
There are the following three sources of errors in the Motion Control Function Module.
Classification
MC Common Errors
Axis Error
Axes Group Errors
* If an axis error with a minor fault level or higher level occurs, operation is also not possible for an axes group that
contains the axis as a composition axis.
Event Levels
This section describes the operation of the Motion Control Function Module for each event level.
Event level of the error
Major fault
Partial fault
Minor fault

Event logs
If an error is detected in the common portion of the Motion Control Function Mod-
ule, the corresponding bit in the MC Common Error Status variable shows the
error.
If an error is detected for an axis, the corresponding bit in the Axis Error Status
variable shows the error.*
If an error is detected for an axes group, the corresponding bit in the Axes Group
Error Status variable shows the error.
All NJ-series Controller control operations stop for errors in this event level.
All control operations for one of the function modules in the NJ-series Controller
stop for errors in this event level. If a partial fault level error occurs in the Motion
Control Function Module, all function of the Motion Control Function Module, such
as axis operation, stop.
Some of the control operations for one of the function modules in the NJ-series
Controller stop for errors in this event level. If a minor fault level error occurs in the
Motion Control Function Module, the relevant axis or axes group stops.
Errors in the observation level do not affect NJ-series Controller control opera-
tions. Observations are reported in order to prevent them from developing into
errors at the minor fault level or higher.
Events that are classified as information provide information that do not indicate
errors.
