If the Panasonic Controller's ERR/ALM LED is flashing, this indicates a syntax error or self-diagnostic error. To resolve this, first check the error code using the programming tool. If it's a positioning operation error, press the [Positioning errors] button, then the [Clear Error Log] button, followed by the [Yes] and [Close] buttons. Clear the errors by pressing the [Clear errors] button. Correct any positioning parameters or tables, and download the corrected data.
