● CNC-350 About min. resolution unit of C axis motor gives feedback from the motor to controller

Ans:

The min indexing for CNC control input is 0.001 degree ,for example ,  you can input 15.001 degree into controller .
As for the AC servo motor encoder of C axis is 10,000 pulses, the C axis rotary table gear ratio is 1 : 90 , so C axis servo motor rotate one circle , the rotary table rotate 4.0 degree .
One pulse rotating degree is 4.0 degree / 10,000 pulse = 0.0004 degree .
