I was able to control the speed up to 21,408 according to the vfd, and 21,640 in Mach3.

So this is very promising.

21k is very satisfactory, now I just need to get the startup to be 0 or learn how to change bits at 6k rpm...I dont think my fingers will be around to try more than once...



AH HA!!!, just went back out realizing I know how to fix this. I dropped 73 back down to 0, now on powerup the spindle is stopped, but "ready to run" instead of starting at 6k.

Now my top speed is 20 ,566 on vfd and 21,640 on mach3

I can live with that, but might be able to do some minor tweaking now to get it dialed in a bit more at least to get the VFD and Mach3 to be reporting the same.

Thank you so much for you help. I think I will go through and follow the spindle tuning document that I linked earlier and see how that puts things.

No first you have to set the correct VFD Drive Parameters, or you will damage the Drive, here is what you need to set, if you have the 2.2 Kw spindle

PD000=0 for Parameter unlock ( 1 ) for Parameter Lock

PD001=0 (1 For Remote Control)

PD002=0

PD003=400

PD004=400

PD005=400

PD007=20

PD008=220

PD009=15

PD010=8

PD011=120 (Minimum Setting 120)

PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings

PD014 Accel=12 ( Adjust to suit)

PD015 Deccl=12 (Adjust to suit) ( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)

PD141=220 ( Motor Rated Voltage ) (120 for VFD Rated for 120v )

PD142=9 ( Motor Max Amps) (Set for your motor Amp Rating 2.2Kw Spindle 9 amp Max)
(Set for your motor Amp Rating 1.5Kw Spindle 7 amp Max)

PD143=2 ( Motor Number of Poles)

PD144=3000 (Max Motor RPM) =3,000= (24,000)

PD002=1 ( For Remote Pot use )

PD70=0 ( This may need to be set to 1 for normal use )

PD72=400

PD73=120
