Hi,
I have been trying to adjust the BEMF compensation parameters for my stepper motor on a EVAL6470H board. I am using the Dspin evaluation software on WindowsXP and an STEVAL-PCC009V1 communications board. I am monitoring the winding current with an oscilloscope and and clamp meter.After hours of trying I was unable to achieve any change in the current drawn by my motor at any particular speed, no matter what parameters I enter for the starting slope, intersect speed, or final acc/dcc slope. I am attempting to keep the motor current near 1.5a rms up to about 1600 cps, but the current rises steadily over the speed range. I can adjust the KVAL parameters and affect the level of the current drawn, but the ''slope'' seems to remain the same no matter what values I enter in the parameters mentioned. I can see no effect on the current drawn at any speed no matter what settings I enter for these parameters. Can you give any adivce? Is there a bug in the Dspin software or do I perhaps have a faulty EVAL6470H board?Thanks much.2013-04-12 11:17 AM
Hello!
I'm sorry for off-topic, but it seems that you can help me. I'd like to ask, where did you get drivers for your STEVAL-PCC009V1 board and what software do you use? As I see, the software from here is not intended to work with STEVAL-PCC009V1 board but with STEVAL-PCC009V2 one. Do you know, is STEVAL-PCC009V1 workable on Window7 - 64bit? Sorry again, for off-topic. Thanks, Sergey.2013-08-08 01:18 AM
