Full Version: VFD speed control

For those of use that are using Variable Frequency Drives on their equipment it would be a nice feature to be able to control motor/spindle speed via the touch screen vs the need to use a potentiometer. I realize this will require an upgrade to the PCB or a secondary hardware module.
Unfortunately, I am not planning to make TouchDRO control anything for a lot of different reasons.
Besides the fact that this will require a TON of rework of the application and the firmware, I just don't want to deal with the liability of something going seriously wrong.
I added an external control box to my VFD and it sits next to the tablet. It was specific to the brand but most VFD's can be controlled remotely.

I have a similar, but slightly different request.
I wondered if a digital potentiometer or similar device could be incorporated  that could auto adjust spindle speed via the VFD to maintain Speeds & Feeds as diameter is reduced ?
I figured with the Tach feature already included along with inputs from a X & Z axis scales it might be possible to do without a lot of changes.
Not a big deal, but thought I'd ask.
