3. Motor, Abnormalities in Actuator System
The drive circuit of a motor & actuator consists of the three ICs IC601(R2S30202FP). The work of each IC is
as follows.
(1) IC601(R2S30202FP) : 7ch driver
Spindle motor driver: 180° audio drive Type, an analog input, a PWM drive, a Vm=12V.
Stepping motor driver X2: analog input, a PWM drive (differential), a Vm=12V
Loading motor driver: Input/Output PWM drive, Vm=5V.
Focus actuator driver: analog input / output (differential), a Vm=5V
Tracking actuator driver: analog input / output (differential), Vm=5V
Tilt actuator driver : analog input/output (differential), Vm=5V.
