12.4 Programming an Axis of Motion
STEP 7-Micro/WIN SMART provides easy-to-use tools for configuring and programming the
Axis of Motion. Simply follow these steps:
1. Configure the Axis of Motion: STEP 7-Micro/WIN SMART provides a Motion wizard for
creating the configuration/profile table and the position instructions. See "Configuring the
Axis of Motion" for information about configuring the Axis of Motion.
2. Test the operation of the Axis of Motion: STEP 7-Micro/WIN SMART provides a Motion
control panel for testing the wiring of the inputs and outputs, the configuration of the Axis
of Motion, and the operation of the motion profiles. See "Monitoring the Axis of Motion
with the Motion control panel" for information about the Motion control panel.
3. Create the program to be executed by the CPU: The Motion wizard automatically creates
the motion instructions that you insert into your program. See "Instructions created by the
Motion wizard for the Axis of Motion" for information about the motion instructions. Insert
the following instructions into your program:
– To enable the Axis of Motion, insert an AXISx_CTRL instruction. Use SM0.0 (Always
– To move the motor to a specific location, use an AXISx_GOTO or an AXISx_RUN
– To use absolute coordinates for your motion, you must establish the zero position for
– The other instructions that are created by the Motion wizard provide functionality for
4. Compile your program and download the system block, data block, and program block to
the CPU.
Note
Make sure to match the measurement system configuration to the pulses/revolution and
distance/revolution specifications of your stepper/servo motor controller system.

from your program. The AXISx_RUN instruction executes the motion profiles you
configured with the Motion wizard.
