Inhibit an Axis
Inhibit an axis when you want to block the controller from using an axis
because the axis has faulted or is not installed. You can also inhibit an axis to let
the controller use other axes.
See Example: Inhibit an Axis on page 298
and Example: Uninhibit an Axis on
page 299 for more information.
IMPORTANT You can inhibit an axis only if the axis has been previously synched to the
group. If the axis has not been synched to the group, you cannot inhibit the
axis.
You want to block the controller from using
an axis because the axis has faulted or is not
installed.
You want to let the controller use the other
axes.
Table 67 - Inhibit Axes
Before you inhibit or uninhibit an axis, turn off all
axes.
Before you inhibit or uninhibit an axis, know that inhibit/uninhibit of an axis also affects any half axes in the same drive.
1. Stop all motion in the axis.
2. Use an instruction such as the Motion Servo Off (MSF) for the axis.
This process lets you stop motion under your control. Otherwise the axes turn off on their own when you inhibit or
uninhibit one of them.
The controller automatically restarts the connections.
To inhibit the axes, inhibit the communication
module.
Do you want to inhibit the integrated motion on the EtherNet/IP network axes?
• YES—Inhibit the 1756-ENxT communication modules.
• NO—Inhibit the individual axes.
You can inhibit the axes of a module on an individual basis. However, it is more efficient to inhibit all axes at once by
inhibiting the module.

Drives
CIP only connections to the drive with the affected axis
are shut down. Connections and motion on all other
drives axes continue uninterrupted.
