12.2.1 ERR LED Turns ON on the Unit

 Situation
An alarm or error occurred.
 Solution
Check the condition according to the following procedure.
PROCEDURE
1. Display "Device Monitor" under "Online" in FPWIN GR7.
2. Monitor the unit memory (UM00064 or M00066) in which an error code is
stored, and check the alarm/error code.
3. In the case of code 44, monitor the unit memory (UM00207) in which a
positioning error code is stored and check the detailed information. For the
detailed information on positioning errors, refer to the list of positioning
error codes on page 12-6.
4. Check the appropriate way to handle for each error code, switch the mode
to PROG. mode and review the settings or program. (When code 20 or 26
occurs, the unit must be rebooted.)
5. Execute UCLR instruction to clear the error. In the case of alarm (code: U20)
or error (code: 26), turn on the power supply again.
6. Switch the mode to the RUN mode. Once the ERR.LED turns off, the error
state will be cleared. If the LED does not turn off, repeat the above operation.
