MLAxisDriveNumber

 Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Returns the drive In electrical engineering, a drive is an electronic device to provide power to a motor or servo. Control device for regulating the speed, torque and position of a motor. A unit controlling a motor using the current and timing in its coils. number associated with the axis or -1 if the function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. block failed.
