5-3 Servo Control
Servo control is carried out by the VIC3 (VIC and FR MI-COM). The FR MI-COM is used for servo control of motor ON/OFF and
rotational direction, and the VIC is used to output rotational speed and phase control signals. More specifically in terms of signal
flow, the VIC detects the FG/PG and PB-RF signals from the motor, and sends the detected signal information to the FR MI-COM.
Then, the FR MI-COM generates an error signal to be output to the VIC. Thereafter, the VIC outputs an error signal (PWM), which
is driven on the MAIN P.C.B. for sending a control voltage to the motor driver IC.
