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