Scanner
Film Drive NC_MO01
The stepper motor NC_MO01 transports the film
from the gear to the negative mask and further on.
The motor has a step angle of 0,72°. The film is
advanced 125µm per step.
The film position is monitored by the Scanner.
The motor is operated with different currents via
NC_MO01_I0 and NC_MO01_I1.
The clock for the motor is defined by
NC_MO01_CLK; the direction is selected by
NC_MO01_DIR.
A High level on DIR makes the motor turn cw,
looking on the shaft.
Magnet Negative Pressure NC_MG01
The magnet NC_MG01 holds the frame in the
negative mask.
Scanner Carriage SC_MO01
The stepper motor SC_MO01 moves the
Prescanner. The motor has a step angle of 0,72°.
The zero position can be reached by means of
light sensor SC_LS01.
The Scanner is in home position when it is not in
the light path. In this position, the light sensor is
closed.
When the motor is turning cw (when looking on
the motor shaft), the Scanner is moved into the
light path.
The motor is energised by different currents via
SC_MO01_I0 and SC_MO01_I1.
The clock for the motor is defined by
SC_MO01_CLK; the direction is selected by
SC_MO01_DIR.
A High level on DIR makes the motor turn cw,
looking on the shaft.
