Stand-by
When the motor is stopped for a period (about 70~80 msec) during the receive mode, pin 156 of ASIC IC501 becomes a low
level and driver IC401 pin 14 becomes a high level. This causes Q401 to turn OFF, and instead of +24V, +5V is supplied
through D401 so that the motor is held in place. When the system is in the stand-by mode, all of the motor drive transistors are
OFF. Therefore the motor current is OFF.
