(a) Error reset command (M5440+4n)
1) The error reset command is used to clear minor and major error code
storage areas for the drive module of the axis where the error occurred,
and to reset the error detection signal.
2) When the error reset command switches ON, the following processing
occurs.
• When the drive module and output module statuses are normal, the
minor or major error code storage area is cleared, and the error
detection signal is reset.
• If an error status still exists at the drive module and output module, the
error code will again be recorded at the minor or major error code
storage area.
In this case, the error detection signal (M4640+4n) will remain ON.
POINT
Do not switch the error reset command (M5440+4n) ON with a PLS
instruction since this can disable the error reset function.
