Posted on April 24, 2013 at 15:21Hi,I'm exploring the EVAL6470H with my stepper motor.according to the motor electrical parameters, the INT_SPEED should be around 2000 steps/s. The problem is that the L6470 has a maximal limitation of 976 steps/s fo...

Posted on September 12, 2013 at 11:00Hi Enrico,I tried to play a little more with the settings of the L6470 (using the SPIN eval software) to see if I can get better results at high speed, and I found out that if I change the Step Mode to Full Step ...

Posted on August 29, 2013 at 11:33Hi Enrico,Sorry for the late response.You are right, and I do encounter a decreasing phase current starting from around 5000 steps/sec due to lack of BEMF compensation (driver is maxed out).I understand there's noth...

Posted on April 30, 2013 at 16:46Sure.target current - 1Asupply voltage - 24VRm - 6.2 OhmLm - 1.88 mHke - 0.009 V/HzThis gives an INT_SPEED of ~2100 step/s, but I'm limited to ~1000 step/s.If I want to run at 6000 step/s for example, I can calculate...

Posted on April 29, 2013 at 12:24That is what I do, but since this is not the real INT_SPEED of my motor, I can't get a steady current in the acceleration/deceleration phases, and I have to calculate myself a workaround ''final slope'' that will giv...
