Error and Warning Details
Errors detected by the Simple Motion module include parameter setting range errors, errors at operation start or during
operation and errors detected by servo amplifier.
Simple Motion module detection parameter setting range errors
The parameters are checked when the power is turned ON and at the rising edge (OFF ON) of the PLC READY signal
[Y0]. An error will occur if there is a mistake in the parameter setting details at that time.
When this kind of error occurs, the READY signal [X0] does not turn ON.
To cancel this kind of error, set the correct value in the parameter for which the error occurred, and then turn ON the PLC
READY signal [Y0].
Simple Motion module detection errors at operation start or during operation
The errors that occur at operation start or during operation such as the positioning control, JOG operation, or manual pulse
generator operation. If an axis error occurs during interpolation operation, the error code will be stored in both the reference
axis and the interpolation axis.
Note that the axis error No. will be stored only in the reference axis during analysis of the positioning data set in each point of
the positioning start data table in the following cases.
• When the interpolation axis is BUSY.
• When the error occurs in positioning data or parameters unrelated to interpolation control.
If the error occurs at the simultaneous start of a positioning operation, the axis error storage details will differ depending on
whether the error occurred before or after the simultaneous start.
• If the error (illegal axis No., other axis BUSY, etc.) occurs before the simultaneous start, the error "Error before
simultaneous start" (error code: 1990H to 1991H) will occur for the start axis.
• If the error (positioning data error, software stroke limit error, etc.) occurs after the simultaneous start, an error code
corresponding to the axis in which the error occurred will be stored. Because a simultaneous start cannot be carried out
due to this, the error "Simultaneous start not possible" (error code: 199EH) will be stored in all axes in which an error has
The axis operation status will be displayed as "error occurring" for axes in which an error occurred.
If an error occurs during operation, any moving axes will deceleration stop, and their operation status will be displayed as
All axes will decelerate to a stop during interpolation operations, even if the error occurs in only one axis.
Servo amplifier detection errors
The errors that occur when the hardware error of the servo amplifier or servo motor or the servo parameter error occurs.
The servo is turned off at the error occurrence and the axis stops.
Remove the error factor and reset the error, reset the controller, or turn the servo amplifier power supply ON again from OFF.
