*1. Point of turning on the power (Point of loading start)
*2.Recognition time of SW2A"L"
*3. Short break time for loading motor (During this time, 100mS period after 50mS passes, overrun check for motor stop
position is performed. If SW2A turns to "H" during this time, reverse pulse drive is operated. When SW2A turns to "L"
again, it goes back to Break Mode. This action will be repeated a maximum of 3 times.)
*4. Waiting time before moving to the next mode.
