Controlling the Polygon Motor
From when the polygon motor starts and the polygon motor reaches the number of target rotation to before image formation starts, the machine controlsthe rotation speed by referring to the polygon motor rotation speed signal (FG signal).
During image formation, it controls the polygon motor rotationspeed based on BD signal.
Polygon motor rotation speed is controlled by speed-up signal (ACC signal) and speed-down signal (DEC signal).
