generated. The Busy output pin in a motion control function block is set to True when there
is a transition in the Enable input pin’s signal from low to high, and is set to True when the
motion control function block is executed. When the Busy output pin is set to True, output
states (values) still change.

Characteristic of the Aborted output pin
The Aborted output pin in a motion control function block is set to True when the execution of
the motion control function block is interrupted by a command.

Relation between the Enable input pin and the Valid output pin
If the input pin that a motion control function block has is the Enable input pin, the motion control
function block uses the Busy output pin to indicate whether output data/states are valid. The
Valid output pin is set to True only when the Enable input pin is set to true or output data/state
are valid. If an error occurs in a motion control function block, output data/states will not be valid,
and the Valid output pin will be set to False. The Valid output pin in a motion control function
block will not be reset until the error occurring in the motion control function block is eliminated,
and output data/states become valid.

Situation 1: The execution of the motion control function block is interrupted.
Situation 2: An error occurs in the motion control function block.
Situation 3: The execution of the motion control function block is complete normally.
Situation 1: The motion control function block is executed normally.
Situation 2: An error occurs in the motion control function block.
