Error and Warning Details
Error type
Errors detected by the MELSEC iQ-R series modules are classified into three levels: major error, moderate error, and minor
error.
The RD75 detects moderate errors and minor errors.
Moderate errors and minor errors include parameter setting range errors and errors at the operation start or during operation.
Parameter setting range errors
Parameters are checked on the rising edge of PLC READY signal [Y0] (turning on of the signal) and if the setting of a
parameter is not correct, an error occurs.
If this error has occurred, RD75 READY signal [X0] does not turn on.
To clear this error, set the correct value in the parameter with the error and turn on PLC READY signal [Y0].
Errors at the operation start or during operation
There are the errors that occur at the start or during operation in positioning control, JOG operation, or inching operation.
If an axis error has occurred during interpolation operation, Error No. is stored both in the reference axis and in the
interpolation axis.
Note that Error No. is not stored in the axis to be interpolated or simultaneous starting axis for the following cases.
■
The interpolation axis is BUSY
Axis error No. is stored only in the reference axis during analysis of positioning data.
■
An error has occurred in positioning data or parameters that are not related to interpolation
control
Axis error No. is stored only in the reference axis during analysis of positioning data.
■
An error has occurred before the execution of simultaneous start of positioning (such as
invalid axis No. and other axis BUSY)
Error before simultaneous start (error code: 1990H, 1991H) is stored in the starting axis.
■
An error has occurred after the execution of simultaneous start of positioning (such as
positioning data error and software stroke limit error)
The corresponding error code is stored in the axis where the error has occurred.
Simultaneous start not possible (error code: 199EH) is stored in all axes where the error has not occurred because the
simultaneous start cannot be carried out. -1: Error is stored in [Md.26] Axis operation status of the axis where the error has
occurred.
If an error occurs during operation, any moving axis decelerates to a stop and -1: Error is stored in [Md.26] Axis operation
status. During interpolation operation, if an error occurs even in one axis, all axes decelerate to a stop.
