■Example settings when using a rotary encoder as the load-side encoder of a roll feeder
• Conditions
Servo motor resolution: 67108864 pulses/rev
Servo motor-side pulley diameter: 30 mm
Rotary encoder side pulley diameter: 20 mm
Rotary encoder resolution: 67108864 pulses/rev
If the pulley ratio or reduction ratio is not one-to-one, calculate the electronic gear by taking that into consideration.
