e. Output Timing of Motor Control SignalsThe scanning motor (M2) is controlled so that the step angle occurring when itrotates is small by incrementally increasing the current of the drive pulse command(SCA, SCA*, SCB, SCB*) generated by the motor driver 1 PCB (high speed response,low amplitude drive, low noise drive).Figure 3-303 shows the relationship between the size (current) of the drive pulsesignal and the timing.Figure 3-303CHAPTER 3 EXPOSURE SYSTEMCOPYRIGHT © 1997 CANON INC.
