Example of Changing Input Signal Allocations
The following example shows reversing the P-OT (Forward Drive Prohibit) signal allocated to
CN1-42 and the /P-CL (External Torque Limit) signal allocated to CN1-45.

Confirming Input Signals
You can confirm the status of input signals on the I/O signal monitor. Refer to the following sec-
tion for information on the I/O signal monitor.
9.2.3 I/O Signal Monitor on page 9-7
+24 V
A reverse signal (a signal with "/" before the signal abbreviation, such as the /
S-ON signal) is active when the contacts are ON (closed).
A signal that does not have "/" before the signal abbreviation (such as the P-
OT signal) is active when the contacts are OFF (open).
The input signal is not allocated to a connector pin and it is always active.
If the signal is processed on a signal edge, then it is always inactive.
The input signal is not allocated to a connector pin and it is always inactive.
Set the parameter to 8 if the signal is not used.
+24 V

S-ON signal) is active when the contacts are OFF (open).
