See the Setup section of the Installation and Setup manual for your
motion controller for more information on position lock tolerance.
When Lock_status = 1, Axis_status = 0 if no faults are active and no
motion is being commanded on the axis.
When Lock_status = 0, Axis_status = 1 if no faults are active and no
motion is being commanded on the axis.
Move Status
Move_status is a logical (Boolean) variable which has values of:
• 1 (true) if the axis is being commanded to move
• 0 (false) if not
In the Tag Explorer, select both Axis System Variables and the desired
physical or imaginary axis, then select Move_status in the Tag Window.
Moves are initiated by a Move Axis block and stopped by a Stop Motion
block.
When Move_status = 1, Lock_status = 0, and Axis_status = 3 if no faults
are active on the axis.
