2.3 SERVOMOTOR/DRIVE OPERATION
The introduction of servomotor technology to the press roll feed has pushed the limits of accuracy, adjustability,
and performance to levels previously unattainable.
The following example is based on the Ultra Edge Servo Roll Feed Standard, US (SRF-125, 200, 300, 400, 500,
600) models. The actual numbers for SRF-100 or metric models are different.
Each revolution of the servomotor produces 1048576 encoder pulses. Every 2.909 revolutions of the servo motor shaft
produce 1 revolution of the feed rollers. The circumference of the lower roll is approximately 11.138 inches.
When a new feed pitch is entered into the system, the built in computer calculates the correct number of electronic
“pulses” it must receive from the motor mounted encoder in order to rotate the feed rolls the correct distance.
