  • I know this is an old post, but I had the same problem with having to reset the board. By resetting the board you are putting the L6470 chip back into default so anything you set in the arduino setup loop get changed to default values (e.g. KVALS). Check your KVALs against your motor specs and adjust to your Vs. The default values on chip reset are 41. So you are actually only supplying 0.16*Vs after chip reset. As for the speed I am using speeds way below that, so I am not sure. Maybe implementing BEMF compensation would allow for increased speed?

No public wish lists :(
