Adjusting speed with vfd

[motoxy]

Oh dear. I do not know how to adjust the speed on my vfd invertor. Some clues please.

Also I have noticed that one of the membrane switches on the control unit, the set button, no longer clicks. Not sure if its working or not. Anyone blown up an invertor and could supply me with the small unit I would be grateful.

I have done a small test cut but only have a spindle speed of 7200 rpm. As soon as I do a 'proper' cut you lucky people will be treated to a video. I know, you can't wait.

this maybe is not clear. I have tried the up and down arrow keys when it is on freq or rpm and that does not change it. I presume that here is a setting \i need to alter. What really gauls me is when I gor this and tested it months ago Jonathan explained this to me. Old age is my best excuse.
