Dear all, At first, I used latency-test to check my computer and I set the BASE_PERIOD to 25000. I used Integrator manual to calculate the INPUT_SCALE but it is not correct. My machine requirements: Unit using mm. I hope the max rpm of motor is 1200. I use SANYO DENKI servo motor which has an 2000 ppr internal encoder and max rpm is 3000. The motor mounts a 16T pulley and connects a 36T pulley. http://myweb.polyu.edu.hk/~icwfchan/p2.png 36T pulley mounts a lead screw which is 4 turns per inch http://myweb.polyu.edu.hk/~icwfchan/p3.jpg
According to Integrator manual, my calculation is: INPUT_SCALE=2000 * (36/16) * (4 /25.4)=709 but the computer displays x-axis value is not the real-distance value. I try and error to find the value round 1250 Would you mind telling me which part is wrong?
