I/O Circuit Identifiers and Signal Names

I/O circuit identifiers provide a consistent method of naming the I/O circuits. For example, IN1

refers to the first of three differential / single ended 5v inputs for each axis.

Signal names are assigned to the circuit identifiers for each axis.

The signal name consists of the

circuit identifier followed by a suffix A-D to identify the axis connector

. Differential circuits also

have suffixes P (positive) and M (minus) to identify the (+) and (-) signal for each differential

pair.

Example

: OUT2 is the circuit identifier for the first differential 5v output on each connector. The

signal names associated with circuit OUT2 are:

Table 3-9. Signal Names Associated with OUT2

Axis: Axis 1 Axis 2 Axis 3 Axis 4

Connector: A B C D

(+) Output Signal: OUT2P_A OUT2P_B OUT2P_C OUT2P_D

(-) Output Signal: OUT2M_A OUT2M_B OUT2M_C OUT2M_D

I/O Circuit Function and Pin Assignments

The next three tables list the I/O circuit functional assignments as well as the connector and terminal board

pin assignments for each axis connector. Although each connector has the same I/O circuits, the functional

assignment of the I/O circuits is axis dependent:
