So i just finished up installing my VFD. My spindle is a 24000rpm spindle. The VFD speed control uses a 10v signal to tell it the speed. But some reason i cant get it to go the right speed that mach tells it.
If i set mach to max 24krpm and tell it to run 12krpms its is actualy running at 15krpm. But if i twist the nob on the speed controller going to the VFD so that its running at 12krpm instread of 15k then it runs slower than 24krpms when you tell it 24k.
Id like to get it running within 500rpm of the actualy speed typed in. Is this possable?
