Other Parts Discussed in Thread: DRV8305, MOTORWARE
I'm doing a project trying to control a PMSM multipol motor using the LaunchPadXL (TMS320F28069M) with DRV8305 driver platform.
I will try to use the sensorless feature -but also have the possibility to test the sensored function afterwards. The driver should be quite simple - velocity driven.
is it correct understood that 28069M only can operate with examples using motion (LAB 5(x), 6(x),10b, 12(x) ?
I have found the inertia in 5c, but the velocity cannot be changed in 5d. I can see that the gMotorVars.SpeedTraj_krpm is changing when I change gMotorVars.SpeedRef_krpm, but the commutation frequency is steady.
the speed feedback seems to work (regulates). when I turn down the gMotorVars.SpeedRef_krpm below 0.1 the motor stoppes, and cannot be activated again.
I can see that to current is increacing if I put a load on the motor so the regulation seems to work.
How do I ensure that the Velocity handel is routed to the FAST estimator?
