Hi everyone

i have a Denford trial mill which iam converting.
its been running fine on mach 3 but the spindle wasn't very good so i have changed it for a 2.2kw 3ph 220v chinese spindle and geared it down 2.5:1 .

all the mechanicals are done , i have the spindle running .i connected the inverter to a plug just to see if the motor was ok . i have the f001 setting at 400hz and when i hit the run button it spins up to 400hz i cannot step it up or down via the arrowed buttons so something isn't right .


i will want to control the vfd by a relay that comes on when the pc has an m3 command , and it also has a 0-10v output board so i want to use this to control the speed.

i need help can someone help with the vfd settings and what to connect to where to get this going


cheers steve
