HW 4.12 with FW 3.27 seems to have some troubles in BLDC mode, but not in FOC mode, and not with FW 2.18!

Test done with TMOTOR U8 not loaded.

BLDC mode sensored (I've glued sensors an tested with other controllers), and detection works well quickly.

Duty cycle mode works, Current mode works, but not speed mode (violent cogging, erratic, and sometime reverse rotation).

Any other people having experiment that problem?!

Have a Nice Day.
