The following figure shows rungs to redefine the axis position of a motion control
application program using the Motion Arm Watch (MAW) instruction.
Watch Position Example
The following example shows the ladder logic to:
• Create a watch position event
• Enable an output when the trigger condition occurs.
Rung 0:
This rung arms a watch position event for Axis_1 when the arm_ watch bit
transitions from false to true
When the MAW instruction begins executing, the Axis_1.WatchEvStatus bit
resets. This bit sets when the actual position of 500 in the forward direction.
Rung 1:
This rung enables the cut output when the watch position occurs. (The
MAW_1.PC bit sets when the watch position occurs.)
The Motion Disarm Watch (MDW) instruction is used to disarm watch position
event checking for the specified axis.
This information applies to the CompactLogix 5370, ControlLogix 5570,
Compact GuardLogix 5370, GuardLogix 5570, Compact GuardLogix 5380,
CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, and GuardLogix
5580 controllers. Controller differences are noted where applicable.
Use the Motion Disarm Watch (MDW) instruction to disarm watch-position
event-checking for an axis. This instruction has the effect of clearing both the
Watch Event Status and Watch Armed Status bits in the axis data structure.

Summary

LOGIX 5000 Controllers Motion Instructions

Motion State Instructions

Motion Axis Fault Reset (MAFR)

Use the Motion Axis Fault Reset (MAFR) instruction to clear all motion faults for an axis. This is the only method for clearing axis motion faults.

Motion Axis Shutdown (MASD)

Use the Motion Axis Shutdown (MASD) instruction to force a specified axis into the Shutdown state.

Motion Axis Shutdown Reset (MASR)

Use the Motion Axis Shutdown (MASR) instruction to transition a group of axes from the shutdown operating state to the axis ready operating state.

Motion Move Instructions

Motion Axis Stop (MAS)

Use the Motion Axis Stop (MAS) instruction to stop a specific motion process on an axis or to stop the axis completely.

Motion Axis Home (MAH)

Use the Motion Axis Home (MAH) instruction to home an axis. Two different homing modes can be selected during axis configuration: Active or Passive.

Motion Axis Jog (MAJ)

Use the Motion Axis Jog (MAJ) instruction to move an axis at a constant speed until you tell it to stop.

Motion Axis Move (MAM)

Use the Motion Axis Move (MAM) instruction to move an axis to a specified position.

Motion Change Dynamics (MCD)

Use the Motion Change Dynamics (MCD) instruction to selectively change the speed, acceleration rate, or deceleration rate of a move profile or a jog profile in process.

Motion Calculate Cam Profile (MCCP)

The Motion Calculate Cam Profile (MCCP) instruction calculates a cam profile based on an array of cam points.

Motion Axis Position Cam (MAPC)

The Motion Axis Position Cam (MAPC) instruction provides electronic camming between any two axes according to the specified Cam Profile.

Motion Axis Time Cam (MATC)

The Motion Axis Time Cam (MATC) instruction provides electronic camming of an axis as a function of time, according to the specified Cam Profile.

Motion Group Instructions

Motion Group Stop (MGS)

The Motion Group Stop (MGS) instruction initiates a stop of all motion in progress on all axes in the specified group by a method configured individually for each axis or as a group via the Stop Mode of the MGS instruction.

Motion Group Shutdown (MGSD)

Use the Motion Group Shutdown (MGSD) instruction to force all axes in the designated group into a Shutdown state.

Motion Group Shutdown Reset (MGSR)

Use the Motion Group Shutdown Reset (MGSR) instruction to transition a group of axes from the shutdown operating state to the axis ready operating state.

Motion Event Instructions

Motion Configuration Instructions

Multi-Axis Coordinated Motion Instructions

Motion Coordinated Linear Move (MCLM)

Use the MCLM instruction to start a single or multi-dimensional linear coordinated move for the specified axes within a Cartesian coordinate system.

Motion Coordinated Circular Move (MCCM)

Use the MCCM instruction to initiate a two or three-dimensional circular coordinated move for the specified axes within a Cartesian coordinate system.
