CHAPTER 2 BASIC OPERATION
2.
Controlling the Stack Processing Motor (M2)
The stack processing motor (M2) is a 4-phase stepping motor.
The direction of rotation (clockwise/counterclockwise) and the speed of the motor are
controlled by the phase of the pulse signals BUNDPINA and BUNDPINB from the CPU to Q16,
which generates pulse signals A, A*, B, B* in response for control.
The motor torque is controlled based on combinations of current control signals BUNDCUR1
and BUNDCUR2 from the CPU to Q16.
The machine drives the motor using a high torque when rotating it clockwise (to drive the stack
delivery belt); on the other hand, it drives the motor at a low torque when rotating it
counterclockwise (to drive the returning roller).
