hi friends , thankx for reading my this post.
my problem is =
**broken link removed**
i am using the driver which is in the datasheet of l298. i am using it with 24v 20amp bettery(bcoz that is a good power supply). and i am applying 2.34V to Vref , and the sense resistors value is 0.4/5W. it means that my motors are running at 0.98 amp. my stepper motor is 20KG/CM 1amp bipolar.
but the problem is = stepper motor is not going more then 150 Rpm. it doesn't matter if i use half or full step, in runs 150rpm in both modes.
so, plz plz plz plz help me to solve this problem. i want to increase the speed of my motor from 150 to at-list 300 rpm. i will be really thankful to you all.
(i think there is some problem with the chopper rate(i read it from some other online forum that chopper rate can effect stepper motors performance).
i am curently using the same resistors and capacitors as the data sheet is showing.= 3.3nf capacitor,22k resistor, the 470uf25V capacitor.)
plz plz plz plz plz plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz help me ..(i am controlling this driver form Ubuntu EMC2)
