Using Only The X Axis And Not The Y Axis On The Cj1W-Nc213/ Nc233 (Unit Versions Earlier Than 2.3) - Omron CJ1W-C113 - REV 02-2008 Operation Manual

Connection of Unused Axes
3-7-2 Using Only the X Axis and Not the Y Axis on the CJ1W-NC213/
NC233 (Unit Versions Earlier Than 2.3)
62
On PCUs with a unit version earlier than 2.3, specified unused axes require
wiring only for the emergency stop input signal.
Based on Example 2: Mode 1 Connection on page 50, the following example
shows the connections for the CJ1W-NC213/NC233 when only the X axis
(and not the Y axis) is used. In this example, the limit input signals for both
axes are set to N.C. contacts. With the CJ1W-NC413/NC433, if the Z axis is
used and the U axis is not used, the connection will be the same with X and Y
replaced by Z and U respectively.

When there is an unused axis, connect the emergency stop input signal (N.C.
contact) and the CW/CCW limit input signals (N.C./N.O. switchable) for that
axis so that they are ON. If the parameters are at their default settings, the
CW/CCW limit input signals are N.C. contact inputs and so connect an input
power supply and keep power ON.
If the emergency stop input signal and the CW/CCW limit input signals for an
unused axis are not ON, a sensor input error (error codes 6000, 6100, or
6101) will be generated for the axis, and the ERC indicator as well as the LED
indicator for the axis will light or flash. The used axis, however, will continue to
operate normally even if an error is generated for the unused axis.
Note If the CW/CCW limit input signals for the unused axis are set to N.O contacts
using the parameter settings, it is not necessary to wire the CW/CCW limit
inputs. For details, refer to 4-4 Axis Parameter Area.
