MC_MoveAdditive
Move additively
10MC11T
Explanation of the Instruction:
MC_MoveAdditive is applied to control the terminal actuator to move for an additive distance at a given speed
and acceleration.
When the former instruction is related with position and it has not completed its given distance,
MC_MoveAdditive is executed to control the terminal actuator to move for the distance which includes the
uncompleted distance left by the former instruction and the distance given to this instruction. When execution
of this instruction is finished, the final position of the terminal actuation is the addition of the given distance for
the former and the current instruction.
If the former one is velocity instruction, MC_MoveAdditive will terminate the execution of velocity instruction,
move for the given distance at a given speed, acceleration and deceleration and then stop.
