1 (true) if the feedback loop of a servo axis is enabled

0 (false) if not

In the Tag Explorer, select both Axis System Variables and the desired
physical axis, then select Feedback_status in the Tag Window.

You can directly enable feedback using a Feedback block with Feedback

depending on the selected homing procedure.

You can directly disable feedback using a Feedback block with Feedback
Off selected. Feedback can also be disabled by a Stop Motion block
(depending on the selected mode), and by certain axis faults, depending
on the fault action setups.

When Feedback_status = 1, Axis_fault = 0 and Axis_status

5 if no

faults are active on the axis. If no other faults are active on any axis,
Global_fault = 0.

When Feedback_status = 0, Axis_fault = 0 and Axis_status = 6 if no
faults are active on the axis. If no faults are active on any axis,
Global_fault = 0.

Homing Status

Homing_status is a logical (Boolean) variable which has values of:

1 (true) if the axis is homing

0 (false) if not

In the Tag Explorer, select both Axis System Variables and the desired
physical or virtual axis, then select Homing_status in the Tag Window.

When Homing_status = 1, Axis_status = 4 if no faults are active on the
