VFD Has defantly blown up now!

I tried all the settings in program 002 and still don't seam to have control over the speed via Mach 3 only on and off.

Is there maybe something else as well that needs to be switched at the same time?

From the manual:-

PD001: Command source. Set to 0. 0 means you're controlling the spindle via the front panel controls. 1 means you're using controls that you've wired up to the screw terminals. 2 means you're going to control it using RS-485.

PD002: Speed control source. Set to 1. 0 means you're controlling the speed through the up and down front panel buttons. 1 means you're going to control the speed with either the knob on the front or an external potentiometer. 2 means RS-485.

When PD002 is set to 1, there is also a jumper next to the screw terminals that you have to set. If the jumper is on the right pair, the control is the front panel knob. If the jumper is on the left pair, the control is via an external potentiometer connected to the screw terminals. Make sure the jumper is on the right-side pair.
