*5. Pulse driving (low-speed mode) time
*6. Recognition time of SW1A switching from “L” to “H”
*7. Switching point from low-speed to high-speed mode
*8. Switching point from high-speed mode to low-speed mode.
*9. Pulse driving (low-speed mode) time
*10. Active point of MECHASW
*11. Recognition time of SW2A”L”
*12. 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, forward 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.)
*13. Waiting time before moving to the next mode.
