3.3.1 Input Signal Allocations
3-26
Input signal allocation at factory setting can be checked using the parameters Pn50A and Pn50B.
(2) Changing Input Signal Allocations
When changing input signal allocations, set Pn50A.0 to 1 to enable making the changes.
Input signals are allocated as shown in the following table.
Refer to the Interpreting the Input Signal Allocation Tables and change the allocations accordingly.
<Interpreting the Input Signal Allocation Tables>
Pn50A
Uses input terminal with factory setting.
Allocates /S-ON signal to CN1-40.
Allocates /P-CON signal to CN1-41.
Allocates /P-OT signal to CN1-42.
Analog
Pn50B
Allocates N-OT signal to CN1-43.
Allocates /ALM-RST signal to CN1-44.
Allocates /P-CL signal to CN1-45.
Allocates /N-CL signal to CN1-46.

• Inverting the polarity of the Servo ON, forward run prohibited, and reverse run prohib-
ited signals from the factory setting will prevent the main circuit’s power supply from
being turned OFF or the overtravel function from working in case of signal line discon-
nections or other failures.
If this setting is absolutely necessary, check the operation and confirm that there are
no safety problems.
• When two or more signals are allocated to the same input circuit, input signal level is
valid for all allocated signals, resulting in an unexpected machine operation.
