*1 The software stroke limit check is carried out for the following addresses during circular interpolation control.
(Note that "[Da.7] Arc address" is carried out only for circular interpolation control with sub point designation.)
Current value/end point address ([Da.6])/arc address ([Da.7])
• If an error is detected during continuous path control, the axis stops immediately on completion of execution of the
positioning data located right before the positioning data in error.
If the positioning address of positioning data No. 13 is outside the software stroke limit range, the operation immediately stops
after positioning data No. 12 has been executed.
• During simultaneous start, a stroke limit check is carried out for the current values of every axis to be started. Every axis will
not start if an error occurs, even if it only occurs in one axis.
Setting method
To use the "software stroke limit function", set the required values in the parameters shown in the following table, and write
them to the Simple Motion module.
The set details are validated at the rising edge (OFF ON) of the PLC READY signal [Y0].
Refer to the following for the setting details.
