Overview of Sample Project
This quick start instruction serves to enable users to the use the motion control feature on Micro830 and Micro850
controllers. It uses a sample simulation program to familiarize the user with motion control instructions and related
parameter and wiring configurations. In particular, this project lets the user enable an axis, home an axis, move an axis, and
use touch probe to capture current position in a simulated environment.
The project uses the minimum components to use motion control. It does not require a servo drive. The PTO output is
wired directly to the high speed counter input. It makes use of high speed counter inputs to count the pulse train output
(PTO) for the current position.
The following diagram illustrates how this project simulates motion control. The elements of this project are shown in the
following diagram.
Download the Simulation Project
You can also download the code for the complete simulation project from the following link:
http://www.rockwellautomation.com/go/scmicro800
The downloadable code includes an optional PanelView Component (PVc) program, which allows the user to easily update
and monitor different axis parameters through a PVc screen.
If you opt not to use a PanelView Component, use the Connected Components Workbench software to toggle variable
input values and trigger motion instructions. Axis monitoring can also be done through the same software through the Axis
Monitor feature.
To get started, check that your Micro800 controller supports motion control.

Axis Monitoring
Note that while in DEBUG mode, you can always check the status of your axis and access diagnostic information through
the Axis Monitor feature in Connected Components Workbench.
Publication 2080-QS001A-EN-E - January 2013 53
Chapter 5 Execute Your Motion Control Function Blocks
Power Up the Motion Axis
The MC_Power function block controls the power stage of the axis, whether ON or OFF. The MC_Reset function block
transitions the axis state from ErrorStop to StandStill by resetting all internal axis-related errors. The outputs of the
function block instances are not changed.
The Axis_PowerUp variable has an initial value of TRUE so the axis powers up as soon as the controller enters RUN mode.
When the axis is powered up, the DriveEnable output is TRUE.
The SWReset variable is set to initial value of False so that the MC_Reset function block does not execute until
thePanelView Component sets it to True (or SWReset is set to True in Debug mode in Connected Components
Workbench using the Variable Monitor). Setting the SWReset variable to True clears any errors.
To use this sample project with the PanelView Component, you can download the PanelView Component program code
for the project from the following link:

Execute Your Motion Control Function Blocks Chapter 5
The axis reverses direction as soon as it
encounters the Home Sensor.
The following sequence describes the homing method used in this simulation project:
1. Moving part moves to its left side (in negative direction);
2. When home switch is detected, the moving part decelerates to a stop;
3. Moving part moves back (in positive direction) in creep velocity to detect Home Switch On → Off edge.
4. Once Home Switch On → Off is detected, record the position as mechanical home position, and
decelerate to stop;
5. Move to the configured home position (the mechanical home position recorded during moving back
sequence, plus the home offset configured in axis configuration in Connected Components Workbench.
Execute MC_Home
The MC_Home function block commands the axis to perform the "search home" sequence. The Home Sensor is
connected to the configured Home Switch input (see Configure Homing Properties
For this simulation, the initial position is initialized to 300 mm so that when the homing sequence starts in the negative
direction, the axis moves to the left until the Home Sensor is reached. The axis then reverses direction and creeps back until
the Home Sensor is encountered again and the Home Sensor input transitions from True to False. The negative edge is used
to mark the Home position.

The function block completes at "StandStill" if the homing sequence is successful.
MC_Home can only be aborted by the function blocks MC_Stop or MC_Power. Any abort attempt from other moving
function blocks will result in function block failure with Error ID = MC_FB_ERR_STATE. However, homing operation
is not interrupted, and can be executed as usual.

The axis moves 200 mm relative to the current position.
Execute MC_MoveRelative
The MC_MoveRelative function block commands an axis of a specified distance relative to the current position at the time
of the execution.
In this section, you will use the MC_MoveRelative function block to move your axis towards a positive or negative
direction. The initial state of your MC_MoveRelative program (that is, before execution) is shown below.
Before execution, the value of inputs such as distance, velocity, acceleration, jerk, deceleration, and buffer mode is 0.
Execute is False as the application has not been run yet. Outputs such as Done, Busy, Active, CommandAborted, Error, are

Execute MC_MoveAbsolute
The MC_MoveAbsolute function block allows you to command an axis to a specified absolute position at the rate of
Velocity, Acceleration, Deceleration, and Jerk inputs specified.
For MC_MoveAbsolute, direction input is ignored.
For MC_MoveAbsolute function block, the position input is the absolute location commanded to
the axis. For MC_MoveRelative, the distance input is the relative location (considering current axis
position is 0) from current position.
Absolute move requires that the axis be homed. It is a move to a known position within the
coordinate system, regardless of distance and direction. Position can be negative or positive value.
Velocity can be a signed value. Users are advised to use positive velocity.
For MC_MoveRelative and MC_MoveAbsolute function blocks the absolute value of the velocity is
used. Velocity input does not need to be reached if Jerk input is equal to 0.

TIP
Execute MC_MoveVelocity and MC_Halt
The MC_MoveVelocity function block commands a never ending axis to move at a specified velocity until the hard or soft
limit is reached.
Velocity can be a signed value. Users are advised to use positive velocity.
Direction input for the MC_MoveVelocity function block can be used to define the direction of the move
(that is, negative velocity x negative direction = positive velocity).
Before execution, the MC_MoveVelocity program should appear as shown.
For MC_MoveVelocity, direction input value can be 1 (positive direction), 0 (current direction) or -1
(negative direction).
For any other value, only the sign is taken into consideration. For example, -3 denotes negative direction,
+2 denotes positive direction, and so on.
For MC_MoveVelocity, the resulting sign of the product value derived from velocity x direction decides the
motion direction, if the value is not 0. For example, if velocity x direction = +300, then direction is positive.
66 Publication 2080-QS001A-EN-E - January 2013
Execute Your Motion Control Function Blocks Chapter 5
IMPORTANT
1. Update the MC_MoveVelocity input variables as shown.
2. To move the axis to the right, set the direction input value to 1.
Once an axis is flagged with error, and the error ID is not
zero, the user needs to reset the axis (using MC_Reset)
before issuing any other movement function block.
Publication 2080-QS001A-EN-E - January 2013 67
Chapter 5 Execute Your Motion Control Function Blocks
IMPORTANT
The update for axis status is performed at the end of one
program scan cycle, and the update is aligned with the update

Execute MC_TouchProbe
The MC_TouchProbe function block records the current position when the touchprobe input becomes True. This
function block is useful for registering the absolute position of the asynchronous object, for example, the registration mark
of a film for a vertical form fill seal machine.
To record the current position while an axis is moving, set TP_EXE variable to True to trigger the function block. Then,
you have to manually trigger the touchprobe input from the hardware.

Implementing Motion Control in an Actual Environment
While this quickstart allowed you to become more familiar with the different motion control function blocks and enabled
you to power up, home, and move a simulated axis, you will need to implement a different wiring configuration for an
actual environment (that is, with a Servo drive, motor).
To do this, you need to refer to the following publications for wiring and supporting configuration information:
• Micro830 and Micro850 Programmable Controllers User Manual, 2080-UM002
Embedded Pulse Train Outputs")
• Kinetix 3 Motion Control Indexing Application, CC-QS025
