Hi, I have a GS2 VFD with a 3KW Spindle. I have the settings as follows in the pic....Did change P0.03 and .04 to 1800 as the spindle is 18000 rpm. Problem i am having is the spindle maxes out but mach 3 is only at 14000 rpm and the voltage is 7.78. If i go to 18000 in mach 3 the voltage goes to 10.0 but spindle speed doesn't change as its already at max. Name plate numbers on spindle are: v - 220 HZ - 300 RPM - 18000 KW - 3 AMPS - 13 I got these settings from the company i bought vfd and spindle from but it seems something isn't correct. Thanks, Matt { "data-align ": "none ", "data-size ": "full ", "title ": "IMG_5242.jpg ", "data-attachmentid ":121694}

So after talking to customer support all is sorted out now. Because the htz on the spindle is 300 htz some things have to be changed in order for the scaling to work correctly.
P0.02 - VFD HTZ is set to 400
P0.03 - .04 - spindle speed gets set to 240000... 18000/300 = 60 * 400 = 24000
P4.03 - Then the Gain gets set to 75% of 24000 = 18,000
and P6.15 gets set to 300 HZ which is what the spindle is rated at.
I also set 4.01 and .02 back to 0.0
