The motor is energised by different currents via
LH_MO02_I0 and LH_MO02_I1:
I0 0 1 0 1
I1 0 0 1 1
Current 100% 72% 38% 0%
The clock for the motor is defined by
LH_MO02_CLK, the direction is selected via
LH_MO02_DIR.
When the lamphouse is opened, the stepper motor
is switched off.
Settings
− KG: KG5 and UV-IR blocking for colour scans
− RG: RG850 + IR band for IR Scans
− KG + 20%: Calibration for shutter damping
Light Shutter LH_MO03 / CG_MO03
The exposure is executed by a rotating disk (light
shutter / Shutter). The two wings cover the light
path. The cutout (72°) releases the light path (2)
during an exposure.
The light shutter is driven by stepper motor
LH_MO03.
The light sensor LH_LS03 (1) opens just before the
shutter completely opens the light path from the
CLOSED position.
The motor is energised by different currents via
LH_MO03_I0 and LH_MO03_I1. The clock for the
motor is defined by LH_MO03_CLK and the
direction is selected by LH_MO03_DIR.
The motor has a step angle of 1,8°. As the motor is
operated in half steps, the actual step angle is 0,9°.
