Run/Stop Selection at Keep Data Error
This section describes the function for specifying the run/stop status of the user program when the FC6A Series MicroSmart "keep"
data is lost.
The keep data (data that is maintained by the FC6A Series MicroSmart), such as the device values and the current time, is lost
when the FC6A Series MicroSmart power is turned off and left this way for a long time such that the backup battery dies. When the
FC6A Series MicroSmart has lost its keep data and is turned on, a keep data error occurs. You can specify the run/stop status of
the user program when this keep data error occurs.
Specify Stop when unexpected operation may result due to running the FC6A Series MicroSmart when the keep data has been
lost. Specify Run when you want to run the FC6A Series MicroSmart at all times regardless of whether a keep data error has
occurred.
Notes:
• The FC6A Series MicroSmart uses the backup battery to maintain the run/stop status (status of M8000) immediately before the power is
turned off. When the power is turned on, operation starts according to the maintained run/stop status.
• If you turn on the FC6A Series MicroSmart with its maintained data deleted, a keep data error will occur and the value of the special internal
relay M8000 (start control) will be lost.
• If a keep data error occurs, the data kept by the FC6A Series MicroSmart will be lost.
• If you specify Stop for Run/Stop Selection at Keep Data Error, the FC6A Series MicroSmart will stop if a keep data error occurs. To run
the FC6A Series MicroSmart, perform the appropriate operations from WindLDR, an HMI module, or the main unit's function switch. For
details, see "Start/Stop Operation" on page 4-15.
• When a keep data error occurs, the error code is written to special data register D8005 (general error code). For details, see "General Error
Codes" on page 13-3.
