Macros in Motion Control Scripts

Macros allow reuse of motion control parameter values inside a script instead of repeated hard-coding. Every command has a macro that can be included in a command or calculation.

• Use macros to avoid repeating fixed values throughout a script.
• Update a value once in the set-parameter command, then reuse it wherever it is needed.
• Make scripts easier to read, maintain, and adjust for different axes or motor settings.
• Use calculations to convert values into the command format required by the motion controller.

Using Set Parameter Macros

A set parameter command defines a value for an axis. The matching macro stores the value so it can be reused in the script. For example, Set Par XU = 1 sets a value for the X axis, where X identifies the axis and U identifies the type of value.

Macro Names 

Macro names use two characters. The first character identifies the axis, and the second character identifies the parameter value.

• Axis: X, Y, Z, or U
• Parameter: U = units, S = steps per rotation, T = travel in millimeters, D = degrees per step

Example: Reusing an axis value

Set the X-axis steps per rotation to 200. The command includes the axis and the parameter, and the matching macro can be used again in the script.

Command: Set Par XS = 200
Macro: XS (X-axis Steps)
