Current Drive 2W1-2 Phase Excitation Micro Step Drive. It works by 1 step to the direction set by
FMDIR signal, per 1 clock of FMCLK signal given to IC1001. The motor current flows as below. In
phase A: 6V power Q1003 6pin Q1003 1pin FAP signal motor phase A FAN
signal IC1001 14pin IC1001 19pin R1003 GND, or, 6V power Q1003 3pin Q1003
4pin FAN signal motor phase A FAP signal IC1001 16pin IC1001 19pin R1003
GND In phase B: Q1006 3pin Q1006 4pin FBP signal motor phase B FBN signal
IC1001 11pin IC1001 6pin R1004 GND, or, 6V power Q1006 6pin Q1006 1pin
FBN signal motor phase B FBP signal IC1001 9pin IC1001 6pin R1004 GND
The motor driving direction is determined by FMDIR signal.
14.2.3.4. EEPROM Block
- EEPROM (IC1009)
Power-supply voltages: 3.3V
Package: 8pin SOP
Memory Capacity: 2K x 8bit
It shall be READ/WRITE by I2CBUS signal (SCL, SDA). Memorizes
the values of LENS adjust, VIDEO adjust and VIDEO DSP install.
When the power is ON or camera unit is reset, it is READ and
installed to each system.
14.2.3.5. LED Block
A line crack and a control signal relay a Tilt board and a Video board from IP CPU by which
control of LED was mounted on the Main board, and it is inputted into the LED control circuit
mounted in the Lens board.
(As for LED, the 3 color LED is used.)
