Axis : AXIS_REF
The structure that is filled with axis data in the Drive Interface (SM_DriveBasic.lib) is shown
here.
Inputs (VAR_IN)
Execute : BOOL (default: FALSE)
The program organisation unit is activated on a rising edge.
Distance : REAL
Relative distance for the motion (technical unit [u])
Velocity : REAL
Value of the setpoint velocity that does not necessarily have to be reached [u/s]
Acceleration : REAL
Desired acceleration [u/s²]
Deceleration : REAL
Desired deceleration [u/s²]
Outputs (VAR_OUT)
Done : BOOL (default: FALSE)
TRUE indicates that the desired distance has been reached.
