Help with Delta VFD and RPM Controller

[OscarG]

We have a ShopBot 4x8 with Colombo 5hp spindle, delta VFD and have the RPM Controller with the USB Dongle. We can not get the RPM Controller to work, after checking with support were told a few people have gotten the controller to work but they do not know how. We are trying to get spindle to automatically change speed both on warm up and during cut routines, this is what the controller was supposed to do but it is not working. Does any one know how to achieve this?

Oscar, I too have the Colombo 5hp spindle and the delta VFD, with the RPM controller. I was never able to get the RPM controller to work, and I worked on it with SB tech support, to no avail. I have just gotten used to punching the buttons on the VFD.............. Chuck
