4.1 Electrical parts Operation
(1) Bin motor control
The circuit shows the bin shift motor control circuit diagram.
A DC motor is used for the bin shift motor (M1), which is controlled by the drive
circuit so that the bin unit moves up and down.
The bin unit up/down speed is detected and controlled by the shift motor clock
sensor.
The bin unit stop position is detected by the lead cam home position sensor.
When the stapler unit is not at the home position, the 24V power supply is cut off
by the stapler unit home position switch preventing the bin shift motor from rotating
to avoid the bin unit and stapler from colliding with each other.
The bin unit upper and lower limit sensors prevent the overrun of the bin unit.
