If no watch position event has previously been set up for the axis,

Watch_Pos_status is 0.

If a previous watch position event has been set up, Watch_Pos_status is:

• 1 if the previous event occurred

Set up Watch Position events in a Watch Control block, with Arm and

Watch Position. Watch Position events are canceled when the watch

position event occurs, or by using a Watch Control block with Disarm

Output Limit Status

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

• 1 (true) if the servo output voltage of the axis is being limited

• 0 (false) if not

In the Tag Explorer, select both Axis System Variables and the desired

physical axis, then select Output_limit_status in the Tag Window.

The value of the Output_limit_status variable indicates whether the

output voltage of the axis is being limited to the previously entered servo

output limit value.
