NJ-series CPU Unit Motion Control User’s Manual (W507)
When an error occurs, you can connect the Sysmac Studio online to the Controller to check current
Controller errors and the log of past Controller errors. You can also check the cause of the error and
corrections.
Refer to the NJ-series Troubleshooting Manual (Cat. No. W503) for the procedures to check for errors
with the Sysmac Studio.
If you can connect communications between an NS-series PT and the Controller when an error occurs,
you can check for current Controller errors and the log of past Controller errors. You can also check the
cause of the error and corrections.
Refer to the NJ-series Troubleshooting Manual (Cat. No. W503) for the procedures to check for errors
with an NS-series PT.
You can use instructions in the user program to check the error status of each function module. The fol-
lowing table gives the instruction that is used to get error information for the Motion Control Function
Module.
For details on the instructions that get error status, refer to the NJ-series Instructions Reference Manual
(Cat. No. W502).
You can use the error status variables in the system-defined variables and the system-defined variables
for motion control to check for errors that have occurred in the Motion Control Function Module.

Error Status Variables
You can check for errors in each function module of the NJ-series Controller with error status vari-
ables. The following variables show the error status of the Motion Control Function Module.
Checking with the Troubleshooting Function of Sysmac Studio
Checking with the Troubleshooter of an NS-series PT
Checking with Instructions That Read Error Status
Instruction Name Outline of function
GetMCError Get Motion Control Error
Status The GetMCError instruction gets the highest level status (par-
tial fault or minor fault) and highest level event code of the cur-
rent Controller errors in the Motion Control Function Module.

_MC_ErrSta WORD MC Error Status Gives the collective error status of all error sta-
tus for the Motion Control Function Module.
_MC_ComErrSta WORD MC Common Error
Status Gives the collective error status of all errors that
occur for common processing in the Motion Con-
trol Function Module.
_MC_AX_ErrSta ARRAY[0..63] OF
WORD Axis Error Status Gives the collective error status of all error sta-
tus for each axis.
