Good evening everybody,
I purchased a few days ago the ELVPOWERSTEP01 evaluation board, together with the STEVAL-PCC009V2 USB-to-SPI bridge board. It worked fine until a few minutes ago. I was experimenting with a stepper motor. I did not succeed to get the stepper rotating faster than 200 steps/sec. I added all the data I have from the steppermotor, coil resistance, self inductance, max current and voltage. The motor kept resonating at slight higher speeds. Suddenly the powerstep01 got very hot and died....The steppermotor I use is from B&R, so the quality is outstanding. I sold about 400 pieces with my current driver.
In the near future I need another (self designed) stepper controller, so I started with the powerstep01
I was making very slow progress with the powerstep01 IC, though I am not new to steppermotor driving.
Is there anybody else who has got problems in starting up with that IC?
I will order another sample of the ELVPOWERSETP board, and will try it one more time.
I need more info how to tune a steppermotor for the powerstep01 IC.
Is there anyone who experienced the same difficulties?
I hope to hear from anyone soon...
