Transport motor control circuit

The transport motor is a stepping motor driven by the control signal output from the PFC CPU on the

LGC board and rotates the intermediate transport roller.

The transport motor is driven by the pulse signal (MTMA-0, MTMB-0, MTMAB-0, MTMBB-0) output

from the motor driver. These pulse signals are formed based on the reference clock signal (MTMCK-0),

and output only when the enable signal (MTMEN-0) is L level. Also, the rotation speed of the motor can

be switched by changing the output timing of each pulse signal.
