816 Axis Locked and Axis Done Conditions
For example, the figure below shows what happens when a trapezoidal
Move Axis block is executed. The situation is similar for a Jog Axis or
Time-Lock Cam block.
When the move is executed, the command position changes according to
the parameters of the Move Axis block, resulting in the command
velocity profile shown above. (Velocity profiles are used instead of
position profiles because it is easier to see the form of the motion this
way.) In general, the actual position lags behind the command position
(the lag is exaggerated here for clarity) as a result of position error as
shown in the Actual velocity profile.
While a move is in progress, Move_status = 1 (true), Axis_status = 3
(Moving), and Lock_status = 0 (Unlocked).
When the move is done, Move_status = 0 (false), and Axis_status = 1
(Unlocked).
