Folding motor drive circuit, Operates the folding | Toshiba MJ-1103

[E] Folding motor drive circuit

The folding motor drive circuit controls the rotation and stoppage, rotational direction and motor current of the folding motor.

The folding motor is a DC motor which is driven by rotation control signals (DM1-CNT1 and DM1- CNT0) from the CPU of the saddle control PC board, and thus this motor performs a folding operation and the paper is exited to the saddle tray.

DM1-CNT1	DM1-CNT0	Motor rotation	Remarks

L	H	Normal	Operates the folding.

H	L	Reverse	The paper is exited to the saddle tray

H	H	Stop

L	L	Stop	Not used.

For the case when an overcurrent status is detected, a protection circuit is mounted to turn the folding motor off.
