Connection of Unused Axes
This section provides a connection example for the C200HW-NC213/NC413 in
applications where not all axes are used.
2-6-1 C200HW-NC213 – X Axis Only
Based on
Example 2: Mode 1 Connection
on page 39, the following example
shows the external I/O connections for the C200HW-NC213 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 C200HW-NC413, 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 ERR and SENS indicators 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
4-3 Axis Parameters
and
4-8 Setting Data for Unused
Axes

•
Wiring requirements can be reduced by connecting Servo Drivers and PCUs
via a Servo Relay Unit, which provide a connector and a terminal block in one
Unit.
