Hi Guys
I have started looking for a VFD for my Mill project and have some questions that I hope someone can help me with. I understand that certain VFD's do not have any type of isolation protection between the Analog Voltage Control (speed control) and the Mains.
Correct.
It's hard to tell off most documentation, but you still need some way of
creating the 0-10V. The easy answer is just to use an isolated step/dir
or PWM to 0 to 10V converter like
Pete Homann's DigiSpeed board
Proven to work well with Mach.
