3. For sink I/O interface. For source I/O interface, refer to section 3.8.3.
4. When assigning the input device to the CN1-23 pin or CN1-25 pin in the internal speed control mode, internal torque control
mode, or positioning mode, use it at sink input interface. It cannot be used at source input interface. For the positioning mode,
the input devices (DI1, DOG) are assigned to the initial values.
