5.3.3 Input Circuit Signal Allocation
The functions allocated to sequence input signal circuits can be changed. CN1
connector input signals are allocated with the default settings as shown in the
following table.
Note: * The functions of these input signals are automatically switched according to the setting at
parameter Pn000.1 as long as Pn50A.0 is set to 0.
The following parameter is used to enable input signal allocation.
Note: The default setting for parameter Pn50A.0 is 0. Functions and applications in this manual are
generally described for the factory defaults.
 Input Signal Allocation
The following signal can be allocated when Pn50A.0 is set to 1.

/S-ON
CN1-40 is default set for
the /S-ON input signal.
Any terminal from CN1-40 to
46 can be allocated to the
/S-ON signal through the
Pn50A.1 parameter.
