Connection Of Unused Axes; Using Only The X Axis And Not The Y Axis On The Cj1W-Nc213/Nc233 (With Unit Version 2.3 Or Later) - Omron CJ1W-C113 - REV 02-2008 Operation Manual

Connection of Unused Axes

3-7-1 Using Only the X Axis and Not the Y Axis on the CJ1W-NC213/
NC233 (with Unit Version 2.3 or Later)
This section provides connection examples for the CJ1W-NC213 and CJ1W-
NC233 in applications where not all axes are used.
On PCUs with unit version 2.3 or later, wiring is not required for the CW/CCW
limit input signal and the emergency stop input signal for specified unused
axes.
The following figure, based on Example 2: Mode 1 Connection in 3-6 Connec-
tion Examples for Different Types of Motor Driver, shows an example of con-
necting external I/O when only the X axis and not the Y axis is used on the
CJ1W-NC213/NC233. The limit input signal for the X axis is assumed to be
set as an N.C. connection.

To set only the X axis as the axis to be used, set the number of unused axes
to 01 in Axis Parameter Designation of 4-4 Common Parameter Area.
The following table shows the relation for each Unit between the number of
unused axes and the settings.
Setting 1-axis Unit
0 All axes used.
1 Error 0013 occurs.
2 Error 0013 occurs.
3 Error 0013 occurs.
Making this setting eliminates the need to perform wiring for the Y axis.
If other parameters are used in their default settings, the CW/CCW limit input
signal will be set to a N.C. contact input. Therefore, current will flow for the sig-
nal when the power supply for the inputs is connected.
