[F] Additional folding motor drive circuit

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

The additional folding motor is a DC motor which is driven by rotation control signals (DM4-CNT1 and DM4-CNT0) from the CPU of the saddle control PC board, and thus this motor performs a additional folding operation.

DM4-CNT1	DM4-CNT0	Motor rotation	Remarks

L	H	Normal	Operates the additional folding.

H	L	Reverse	Operates the additional folding

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 addi- tional folding motor off.
