Got a brand new 2.2 VFD. I power it up and F00.00 flashes with "for" I wiped it back to the factory settings then input all my settings, powered it off and on and it just keeps flashing. I disconnected and reconnected "DCM" and I heard the relays reset and then it worked. BUT once powered down it starts flashing again and no go! Where do I go from here?

[TheProCreator]

Ok this is weird. I have to set PD001 to 0 and press RUN. I can then turn on the spindle through Mach3 and adjust the rpm's (although they don't match the VFD). When I stop the spindle through Mach3 it slows to a frequency of 120 and does not stop. I then have to press stop on the VFD and then it stops, clicks and the display starts to flash. To start the spindle I have to press run on the VFD (dispaly stops flashing but spindle does not start) and then I can run the spindle through mach3 again.

What is going on??????

Ok, further exploration leads to that the relay is NOT turning on/off the spindle, but the analog setting of 0 on pd070 is. Setting pd011 to 0 brings the spindle to a stop now with out going into that flashing nonsense. I can operate the spindle fine however the rpms are off. So now I want to get the rpms a bit more aligned. Any help or suggestions would be most appreciated.

What relay are you using, the relay that is in the drive is not for start/stop operation, you need an external relay that is controlled by Mach3 to turn it on/off, or PWM on your Breakout board & then you don't need any relays at all

What settings have you put into the Drive, you have to be careful setting these Drives, they are easy to smoke

I am using an external relay. I have a 30DCV power supply powering the CNC. I am using a solid state SPST relay (3-30dcv) on output #1 from the G540. The G540 powers the relay on and off as it should, but the VFD does not respond to it. I have it wired exactly like the Homman Design diagram.

You should of put that in your first post that you had followed the Homman wiring diagram, if this has been correctly done, then you have some Parameters in the VFD that are not set correct
What do you have these parameters set too

PD001
PD143
PD144

[TheProCreator]

Apologies.

PD001 is now 1
PD143 is 02
PD144 is 3000

Thanks for the assistance!

That is correct with what you have them set at, PD001=1 for remote control PD001=0 for key pad, a lot of users miss setting this one for remote use

PD011 is another inportant, Parameter, it can be set as low as 100Hz, it is safer to keep it at 120Hz

[TheProCreator]

yes I have PD011 set to 120hz I noticed that the SS relay took almost 5 seconds before releasing the COM and FOR connection after m3s0 was entered.(or turning off spindle in mach3)

Open Ports & Pins Spindle setup under General Parameters you will see at the bottom, a box to check for Immediate Relay off, this may help to stop that 5 second delay

Ok, It works with a coil relay just fine. Now to get matching RPM's and FQ from VFD and MACH3 how do I figure out pulley speed and motor tuning? If I change either it affects the values and although they are close (+ - 200 rpms) they are not spot on.

This will set your pulley speed setup
