 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 /EXT1 to /EXT3 (External Latch Inputs 1 to 3) signals to pins 10 to 12 on the I/O
signal connector (CN1).
2. Refer to the following section for details on input signal parameter settings.
13.1.2 List of Servo Parameters on page 13-3
Example of Changing Input Signal Allocations
The following example shows reversing the P-OT (Forward Drive Prohibit) signal allocated to
CN1-7 and the /DEC (Origin Return Deceleration Switch) signal allocated to CN1-9.
Refer to the following section for the parameter setting procedure.

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.

Pin No. Description
013
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).

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.
