Error Tables
The following tables show the errors which can occur in the FQM1 and indi-
cate the probable cause of the errors.
cate the probable cause of the errors.
Note Always confirm the safety of connected equipment before turning the power
supply OFF or ON.
CPU Errors
If the following LED indicator condition appears during operation (in RUN or
MONITOR mode), it indicates that a CPU error has occurred. The CX-Pro-
grammer cannot be connected if a CPU error has occurred.
MONITOR mode), it indicates that a CPU error has occurred. The CX-Pro-
grammer cannot be connected if a CPU error has occurred.
If a fatal error occurs, the RDY and ERR indicators will be lit and the RUN indi-
cator will be OFF, but a CX-Programmer can be connected. This difference
can be used to distinguish between a CPU error and other fatal errors.

CPU Standby
If the following LED indicator condition appears when the power is turned ON,
it indicates that the FQM1 is in CPU standby status.
it indicates that the FQM1 is in CPU standby status.
When the FQM1 is turned ON, cyclic servicing starts after the Coordinator
Module recognizes all of the connected Motion Control Modules. Operation
can be started at that point.

If the startup mode is RUN or MONITOR mode, the FQM1 will remain in
standby status until all of the Motion Modules have been recognized..
