Relationship between Parameter Settings, Allocated Pins, and Polari-
ties
The following table shows the relationship between the input signal parameter settings, the
pins on the I/O signal connector (CN1), and polarities.
Note: 1. You cannot allocate the /EXT_A1 to /EXT_A3 and /EXT_B1 to /EXT_B3 (External Latch Inputs 1 to 3) sig-
nals to pins 6 to 8 and 12 to 14 on the I/O signal connector (CN1).
2. Refer to the following section for details on input signal parameter settings.

Example of Changing Input Signal Allocations
The following example shows reversing the P-OT (Forward Drive Prohibit Input) signal allocated
to CN1-4 and CN1-10 and the /DEC (Origin Return Deceleration Switch Input) signal allocated
to CN1-6 and CN1-12.
Refer to the following section for the parameter setting procedure.

A reverse signal (a signal with “/” before the signal abbreviation, such as the
/P-CL 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 inac-
