Case 1
：
Busy changes to TRUE when Execute changes to TRUE. Several cycles later, Active and
InControl change to TRUE.
Case 2
：
When Execute changes from FALSE to TRUE and the instruction is aborted by other instruction,
CommandAborted changes to TRUE and meanwhile Busy and Active change to FALSE.
CommandAborted changes to FALSE when Execute changes from TRUE to FALSE.
Case 3
：
When an error occurs such as axis alarm or Offline after Execute changes from FALSE to TRUE,
Error changes to TRUE and ErrorID shows corresponding error codes. Meanwhile, Busy and
Active change to FALSE and InControl changes to FALSE. Error changes to FALSE when
Execute changes from TRUE to FALSE.

Function
1. DMC_ControlAxisByPos instruction is executed by changing Execute from FALSE to TRUE.
Changing Execute of the instruction from TRUE to FALSE during the instruction execution does not
affect the instruction execution.
2. While Execute changes from FALSE to TRUE once more during the execution of
DMC_ControlAxisByPos, there is still no impact on the instruction execution.
3. The velocity, acceleration and deceleration must be greater than 0. None of them are used in the
calculation of the position control.
4. The Position in this instruction means a relative incremental position. The reference position for the
incremental position is what the value of Postion is when Execute of the instruction changes from
FALSE to TRUE.
For example, the value of Position is 5000 and the axis position is 500. Change Execute of the
instruction from FALSE to TRUE. Then the axis remains motionless and the axis position remains
unchanged. Change the value of Position to 6000 (which has increased by 1000), the axis completes
