Nobody can tell you that with any accuracy because there are far to many variables involved. The tools you will be using and cam strategies your using will dictate most of this and only when you start using larger tools that spin slower and require more torque will you possibly need to start messing with torque tuning the VFD.

Cutting 6061 or most aluminum for that matter unless cutting with large diameter tools 12mm + will require high spindle speeds which is where your highest torque is on these spindles so I wouldn't worry about messing with torque settings or minimum speeds.

I pretty much exclusively cut aluminum and I rarely drop below 12000rpm and if using adaptive stratergies then I'm in the 15-18,000rpm's with 6-8mm 3 flute cutters.
Only with 12mm will I drop to 9-10,000rpm.

If it's working correctly and giving correct speeds at the commanded frequency then just leave it well alone and start making chips is my advise.
