- See Examples of Axis Functions for more information.
- The DeltaPosition input is signed so:
- The move can be in the positive or negative direction.
- The Axis moves this distance in User units.
- The travel speed, acceleration, deceleration, and User units of the move are values inherited from the selected Axis.
- The default settings are entered when an Axis is created and initiated, and can be changed with other MLAxis commands.
