Hello,
I am using TI InstaSpin FOC software on a TMS320F28069M, integrated in a high voltage board with PMSM motor.
In our application, the motor is coupled with a high speed fan.
The fan could be driven by the medium, also if the motor is unpowered.
I am looking for a hint, how to start the instaspin FOC routines, if there is already a certain speed on the motor.
It is clear, that it does not make sense, to use recalibration routines (e.g. for motorresistance or offset-values),
because of the routines would apply measure-currents to the spinning motor.
Is it only an issue to provide the detected motorspeed as target speed to the rpm-controller?
Regards
Martin Bayer
