 Relationship between Parameter Settings, Allocated Pins, and Polarities
The following table shows the relationship between the input signal parameter settings, the
pins on the I/O signal connector (CN1), and polarities.
Note: Refer to the following section for details on input signal parameter settings.
9.2.2 List of Parameters on page 9-4
 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.
Refer to the following manual for the parameter setting procedure.

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).

7–
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.
8–
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.
