Bin: home sensor MS1
The home position of the bin unit is determined when the detecting plate press-
es against the bin home sensor MS1.
When the bin unit moves to the home position, the bin unit first moves down,
then up, for a single rotation of the lead cam: after detection of the home posi-
tion by the sensor MS1.
Upper sensor MS2
The motor M1 will stop if an error occurs, causing the bin unit to continue
moving until the detecting plate presses the upper sensor MS2.
Controlling the bin shift motor
Motor M1 is a DC motor. The direction of rotation is controlled by combina-
tions of the drive pulses from the microprocessor.
When the motor rotates clockwise, the bin unit moves up.
When the motor rotates counter clockwise, the bin unit moves down.
The motor rotates only when:
the upper sensor MS2 is off, and
the home sensor MS1 is off, and
the stapler home sensor MS4 is on.
