16. FULLY CLOSED LOOP SYSTEM
(b) Setting example when using the rotary encoder for the load-side encoder of roll feeder
Conditions
Servo motor resolution: 4194304 pulses/rev
Pulley diameter on the servo motor side: 30 mm
Pulley diameter on the rotary encoder side: 20 mm
Rotary encoder resolution: 4194304 pulse/rev
When the pulley diameters or reduction ratios differ, consider that in calculation.
