So instead of setting to 230, I changed it back to the default value of 370V.
Everything was working fine when controlled from the panel. Lowest allowed setting frequency was 120Hz, maximum was 400Hz. Spindle spun well, was able to speed up and slow down corresponding to the input frequency.
I then connected the board to the inverter and set the parameters for control of spindle by mach3. The spindle was able to be turned on. Speed was able to be controlled with mach3, HOWEVER once frequency was moved to above 270Hz, it cannot come back down below 270Hz. It can start below 270Hz. Another thing to note was that when spindle was switched off with mach3 it takes a much longer time to stop than if controlled by the panel. It was a very similar issue to before. One additional observation was that at 270-290Hz the spindle does not spin smoothly. Your thoughts?
