The ZOOM motor, which type is a stepping motor, is driven with the motor driver (IC1002). The drive
system is Constant Current Drive 2W1-2 Phase Excitation Micro Step Drive. It works by 1 step to the
direction set by ZMDIR signal, per 1 clock of ZMCLK signal given to IC1002. The motor current flows as
below. In phase A: 6V power

FOCUS motor, which type is a stepping motor as ZOOM motor, and which drive circuit is also same type
as ZOOM motor, is driven with the motor driver (IC1001). The drive system is Constant Current Drive
2W1-2 Phase Excitation Micro Step Drive. It works by 1 step to the direction set by FMDIR signal, per 1
