Procedure
»
The control unit on the control board determines the motor rotary speed depending
on the film reel diameter.
»
The frequency inverter transmits the values from the control unit to the motor.
»
The Hall generator board (arrow) on the friction motor (fore side take-up friction)
additionally controls the fore side film reel speed.
If the rear film reel speed is getting too high - the reel diameter is getting larger - a
“too fast” signal will be sent to the control unit.
Then it will transmit a reduced speed value to the Hall generator - the fore side fric-
tion drive reduces its speed.
Friction Shaft
ATTENTION
Always
secure the pinned film spools by screwing on the lock nut (arrow)!
