5.5.7 Using the Warning Output Signal (/WARN)
The basic use and wiring procedure for the warning (/WARN) output signal
(photocoupler output signal) are given below.
The signal consists of the following two output signals.
Note: *CN1-1 and CN1-2 terminals are allocated using parameter Pn50F.3.
This output signal indicates an overload or regenerative overload warning.
The following parameter setting is used to change the CN1 connector terminal that
outputs the /WARN signal.
Pn50F.3 is used to allocate the /WARN output signals above.
Notes: *1 and *2 are output terminals allocated with parameter Pn 510.0.
Multiple signals allocated to the same output terminal follow Boolean OR logic. In order to use the /
WARN output signal alone, set other output signals to a value other than that allocated to the /WARN
signal. See 5.3.4 Output Circuit Signal Allocation.
