Appendix 3 Error Code
Positioning-dedicated error
When an error related to the positioning function occurs, the following special device turns on.
After the device above turns on, an error code is stored in the corresponding special device below.
*1 Only FX5S/FX5U/FX5UC CPU module is supported.
The following error codes are stored in the positioning error (error code). Error codes of axis 4 are available only for the FX5S/
FX5U/FX5UC CPU module.
How to clear errors
Continuation errors can be cleared. ( Page 137 Error clear)

1090H Battery error • Low battery voltage was
detected. Or an error was
detected in a battery keeping
device.
Continue • Check the connection of the battery.
• Replace the battery as soon as possible.

1100H Memory card
access error
• Writing failed because the
write protect switch of the
memory card is enabled
(writing is prohibited).
• An SD memory card was
inserted when the SD memory
card access control switch
was set to OFF (upward).
Continue • Disable the write protect switch of the
memory card.
• Set the SD memory card access control
switch to ON (downward) and insert an
SD memory card.
At write
1120H SNTP time
setting error
• Clock setting has failed when
the system is powered on or
the CPU module is reset.
• Clock setting using the time
setting function (SNTP client)
has failed.
Continue • Check if the time settings are correctly set
in parameter.
• Check if the specified SNTP server is
operating normally and there is no failure
on the network accessing the SNTP
server computer.

failed
• The connection was not
established during the open
process.
Continue • Check the operation of the external
device.
• Use an external device to confirm whether
the open process was executed.
• Review the port No. of the module with
Ethernet, the IP address/port No. of the
external device, and the opening method.
• If the external device has a firewall set,
check whether access is permitted.
• Check whether the Ethernet cable is
disconnected.
