Thanks a lot Ian for your input
When I build the first stepper circuit I did use the logic you explained and I am aware that I have to ramp up and ramp down. But when I hit approx 200rpm and tried to increase the speed the motor just stalled and never moved. I started with 10rpm and ramped up to 200rpm but was and am unable to increase speed. I need 900 rpm from this motor. I am interested to know that on page 88 of the document provided how can you start after two break points shown on the curve. regards James |
