6.1 I/O Signals
6.1.2 Output Signals
6-8
Select whether /ALO1 to /ALO3 are used or /WARN, /BK and /S-RDY are used with the param-
eter below.
/WARN (Warning) Signal
This signal is for an error or warning issued before the occurrence of an alarm. A signal is out-
put for only 2 seconds for errors. A signal is continuously output for warnings until the cause of
the warning is removed. There is no need to stop operation.
The /WARN signal is allocated to CN1-1 and CN1-2 by default.
Note: You can use PnB51 to allocate the /ALO1 to /ALO3 signals instead of the /WARN, /BK, and /S-RDY signals.
Refer to the following section for details.
Alarm Code (/ALO1 to /ALO3) Signals
You can change the setting for the /WARN signal with PnB1C.
Setting the Warning Code Output
You can use the /ALO1 to /ALO3 (Alarm Code Output) signals to output warning codes. Use
Pn001 = n.X
(Warning Code Output Selection) to set the output.
Refer to the following sections for details on the warnings.
