2.2kw spindle set up

[Tenson]

For the water cooled spindle you can set this to as low as you want, since the cooling effect of the water is the same regardless of speed. The spindle torque is practically zero below 3000rpm, so I recommend setting it to 50hz. .

Thanks for saying that, I had wondered about going lower than 100Hz but was a bit scared to burn out the coils. :)
