controlled from the CPU (IC101) on the main board.
[ZOOM drive motor control]
The CPU controls the ZOOM motor drive driver (IC303) mounted on the LENS board by drive timing signal (Z_1, Z_2 and
Z_END) of the ZOOM motor. The output current, pulse period, and the number of pulses are also set up by the driver. This
ZOOM motor drive driver (IC303) controls phase two excitation for the ZOOM lens drive motor. The power supply for motor drive
is used +3.3 V supplied via the Reg. IC (IC208) from +5.6 V supplied via the VIDEO board.
[IRIS drive control]
The IRIS has been adjusted in the factory and the adjusted values are saved in the EEPROM memory (IC204) on the video
board. The adjusted values and the control values are written in the DA converter (IC302) on the LENS board in the initialization
process when the power is turned ON and each V cycle. No subsequent process to write the data into the DA converter will be
carried out. Once the adjusted values are written in the DA converter, the output voltage from the DA converter can be con-
trolled. The DA output is applied in the IRIS control circuit.
