Pn50A.3
Setting
0
Inputs the P-OT signal from the SI0 (CN1-40) input terminal.
1
Inputs the P-OT signal from the SI1 (CN1-41) input terminal.
2
Inputs the P-OT signal from the SI2 (CN1-42) input terminal.
3
Inputs the P-OT signal from the SI3 (CN1-43) input terminal.
4
Inputs the P-OT signal from the SI4 (CN1-44) input terminal.
5
Inputs the P-OT signal from the SI5 (CN1-45) input terminal.
6
Inputs the P-OT signal from the SI6 (CN1-46) input terminal.
7
Sets P-OT signal so that it is always valid.
8
Sets P-OT signal so that it is always invalid.
9
Inputs the P-OT signal from the SI0 (CN1-40) input terminal.
A
Inputs the P-OT signal from the SI1 (CN1-41) input terminal.
B
Inputs the P-OT signal from the SI2 (CN1-42) input terminal.
C
Inputs the P-OT signal from the SI3 (CN1-43) input terminal.
D
Inputs the P-OT signal from the SI4 (CN1-44) input terminal.
E
Inputs the P-OT signal from the SI5 (CN1-45) input terminal.
F
Inputs the P-OT signal from the SI6 (CN1-46) input terminal.
* Settings 9 through F can be used to reverse signal polarity.
IMPORTANT
• Examples of Input Signal Allocation
The procedure used to allocate sequence input signals is described using the P-OT (for-
ward run prohibited) signal as a typical example.
Description
If reverse polarity is set for the Forward Run Prohibited or Reverse Run Prohibited signals, safe opera-
tion may not occur when troubles, such as broken signal lines, occur. You must confirm operational
safety if setting reverse polarity is necessary for one or more of these signals.
As shown in the table above, the P-OT signal can be allocated to any input terminal
from SI0 to SI6. When Pn50A.3 is set to 1, the signal input to the CN1-41 terminal will
be the P-OT signal.
The P-OT signal is not used when Pn50A.3 is set to 8. This setting is used in the follow-
ing instances.
• When the signal input to the CN1-42 terminal is to be replaced by another input sig-
nal.
• When the forward run prohibited (P-OT) input signal is not effective temporarily dur-
ing trial or normal operation.
• When the forward run prohibited status is not required in the system configuration.
Signal Polarity Reverse function: Not active
Example: Forward run prohibited signal (P-OT) is
valid when high (OFF).
Set the forward run prohibited signal (P-OT) so
that it is always valid or always invalid.
Signal Polarity Reverse function: Active
Example: Forward run prohibited signal (P-OT) is
valid when low (ON).
