hi,guys,

how to calc ''Running target current''??

stepper motor parameter:1.5A current?nameplate?this is RMS current???

????

min speed:50 steps/s,max speed 2000 steps/s, ACC 1000 steps/s2,

test board:EVAL6470H && PCC009V2

But in the process of running:

Don't turn

Hi,

parametrs seems ok.

I suggest setting the full-step speed value above the maximum speed (switching to full-step is required in very particular cases only) and adding a small mechanincal load to the motor shaft.

Please, check the IC is in HiZ state before writing the configuration.

Kind Regards
