Feeder Control Board
The Feeder Control Board is responsible for extracting film from the film cartridge and feeding it to the
platen. The board contains, in addition to a slave CPU, drive circuits for three dc motors and two stepper
motors. The Slave CPU receives inputs from eight optical sensors that provide position information
relating to mechanical components that handle film. Timing for all feeder control functions is controlled by
the Slave CPU.
6-4-6-1.
Motor Control
The Feeder Control Board controls the following 5 motors:
•
The Elevator (Stepper) motor, which raises and lowers the film cartridge in the rollback tray.
•
The Rollback (DC) Motor, which rolls the cartridge lid open or closed.
•
The Pickup (DC) Motor, which moves the pickup cups up and down.
•
The Feed Roller Open (DC) Motor, which opens and closes the film feed rollers to capture the film
positioned by the pickup cups.
•
The Feed Roller (Stepper) Motor, which drives the film from the cartridge to the platen rollers.
DC Motor Drive
----The 3 identical bidirectional dc motors operate on +12 volts dc. The drivers for the
motors do not provide current limiting. When the motors are turned on, they are essentially placed across
the +12 volt dc supply. The only control applied to the motors, aside from turning them off and on, is in the
direction of current flow through the motor windings. Each motor driver has 2 control lines coming to it
from the Slave CPU. When these lines are at opposite digital levels, the motor is energized. When the
lines are at the same level, the motor is off. The polarity of the signals applied to the 2 control lines
determines the direction of travel.
Stepper Motor Drive
----The drive circuits for the 2 stepper motors are identical to the stepper drive
circuits on the MCS Board for the Film Centering and Platen Motor Stepper Motors. Each driver requires
from the CPU an enable signal and 2 phase signals (square waves) spaced 90 degrees apart. The
lead/lag relationship of the phase signals determines the direction of current flow through the motor
windings and thus the direction of motor rotation. To start a motor, the Slave CPU configures the phasing
channels for the appropriate direction and sends the required enabling signal, NIP PHASE ON or
ELEVATOR PHASE ON (active low). To stop the motor, the enabling signal is driven high. It is not
necessary to stop the phasing signals to stop the motor. The Elevator Stepper Motor is driven at +12 volts
dc, and the Feed Roller Stepper is driven at +24 volts dc.
