TMS320F28069M: Cancel SpinTac Move

Alex,

You should be able to set the enable bit for SpinTAC Move to false.  There is a function called: STPOSMOVE_setEnable

This will stop the current profile and will generate a new profile that will drive the velocity to 0  (in position) or acceleration to 0 (in velocity) using the configured Halt limits.

Thanks Adam,

This was helpful.

Hi Adam,

I set PosStepInt_MRev to a value and start the PositionProfile.
My Question is how can I read the actual Position.
I want know how many turns are just done.

Thanks Alex

Alex,

You can monitor the position reference signal from SpinTAC Position Move.  This will indicate what the current position reference is.  If you subtract the position start value from the position reference value (keeping in mind the rollover present in the position signal) this could be a way to get a value for how far the motor has gone during this particular profile.
