When the motor is stopped long time (about 70-80 msec) at receive mode, gate array IC404 pin 27 become_ low lewl a,,d
driver IC406 pin 14 becomes high level. This causes Q403 to also go OFF, and instead of +24 V, +5 V is supplied through
D602 so that the motor is held in place. When the system is in the stand-by mode, all of the motor drive transistor is OFF.
Therefore the motor current is OFF.
