I know InstaSPIN-foc use forceangle at startup, when the speed reaches a certain value to switch to the FAST angle.

Please explain in detail the motor starting algorithm combine with the startup function。

thanks

It's a I/f control like general v/f control, will output angle by a startup frequency if you enable forece angle function, and you can set the startup current in user.h.

this is explained in SPRUHJ1

IF forceangle is enabled a rotating forcedangle as set in user.h will be applied instead of an estimated angle from FAST until a certain frequency limit is estimated by FAST

the startup function is run from ROM ?it is not open source ?
I want to read the startup code.
thanks.
