I'm using the Digispeed XL from Homann Designs with a GS3 AutomationDirect VFD and a 3600RPM motor, and I'm having a small problem. The spindle operates as expected, however the speed is not correct. I have a high and low speed. I've set the pulleys up, which the ratio box seems to have no effect on the PWM output. For instance my low speed is a max of 2000 and when I enter M3 S2000 the VFD is only running around 40hz or approx 2400 motor speed.
I'm not sure what exactly I need to adjust? Or what I'm missing here.
Any help is appreciated.
Thanks
