3.4.1 Input Signal Allocations
3-22
(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>
• 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.

Level at which input signal
allocations are valid.
The parameter set values to be used are shown.
Signals are allocated to CN1 pins according to the
selected set values.
Values in cells in bold lines are the factory settings.
If always ON (7) or always OFF (8) is set, signals
will be processed in the multi-winding drive unit,
which will eliminate the need for wiring changes.
