5 Common Command Instructions
Errors
If an error occurs during instruction execution, Error will change to TRUE.
You can find out the cause of the error by referring to the value output by ErrorID (Error Code).
Depending on ErrorID (Error Code), attached information is output to ErrorParameterCode (Parameter
Detail Code) and ErrorNodePointIndex (Node Point Element Number).

Even if an error occurs during execution of the instruction, the cam data variable that is specified for
CamTable retains the values from before execution of the instruction.
However, the values in the cam data variable are not retained in the following cases.
• When the parameter specified for CamNodes is changed after Execute changes to TRUE.
• The value of a cam data Distance (Displacement) calculated by this instruction exceeds the valid
range of REAL data.
If the values in the cam data variable are not retained, the cam table will be in an illegal state. An error
will occur if you specify a cam table that is an illegal state for the MC_CamIn, MC_SaveCamTable, or
MC_SetCamTableProperty instruction.
To recover a cam table from an illegal state, reset the error that occurred for the instruction and then
perform one of the following actions.
• Execute this instruction for the cam table that is in an illegal state again and complete creation of
the cam table.
• Downloaded the cam table from the Sysmac Studio.
• Cycle the power supply to the Controller.
An error code is not output to ErrorID (Error Code) if an error occurs for this instruction in PROGRAM
mode or during an MC Test Run. If that occurs, check the cause of the error in the event log or in the
_MC_COM.MFaultLvl.Code (MC Common Minor Fault Code) system-defined variables for motion con-
trol.
