POINT
(1) If errors frequently occur in the Simple Motion module, "*HST.LOSS*" (instead
of an actual error code) may be displayed in the Error Code column.
(Display example)
If "*HST.LOSS*" is frequently displayed, set a larger value for the number of
errors collected per scan in the PLC RAS tab of the PLC Parameter dialog
box.
For the setting, refer to the "User's Manual (Function Explanation, Program
Fundamentals)" of the CPU module in use.
(2) If the error occurred at the simultaneous start, the axis No. in which the error is
detected is stored in the "Starting axis" in Error History.
