Chapter 5 Execute Your Motion Control Function Blocks

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
