3.3.1 Input Signal Allocations
3-24
Input signal allocation 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.
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.
1. When using Servo ON, Forward Run Prohibited, and Reverse Run Prohibited signals
with the setting "Polarity Reversal," the machine may not move to the specified safe
direction at occurrence of failure such as signal line disconnection. If such setting is
absolutely necessary, confirm the operation and observe safety precautions.
2. When two or more signals are allocated to the same input circuit, input signal level is
valid for all allocated signals.

If always ON (7) or always OFF (8) is set, signals
will be processed in the SERVOPACK, which will
eliminate the need for wiring changes.
