VFD/Spindle wiring Mach3
« on: December 06, 2009, 11:48:06 PM »
I was looking at the manual for the G23 board I'm using and it said to treat the spindle exactly like you would for a stepper motor.  I'm unsure about that.  It seems to me that all my Port 1 outputs are taken, and the outputs to the VFD aren't on Port 2.

I'm wiring up as a sink source according to:

Anybody have an incling about this?  How do you normally wire up your spindle?  I'm understand it's a set it and forget it after your done, but I'm still at the 'set it' part;)

1) Verify the output signals with a Scope/Meter to make sure you breakout board to Mach3 configuration is correct.

2) Make sure your VFD Parameters are setup to accept the FWD, REV and Analog inputs.  Most VFD can be configured several diffent ways on their input pins  (2 wire control, 3 wire control, ... )

Just some ideas...

Let me see if I understand what you are asking and then give a guess  or 2.

You have 2 pports on the computer?

You are wiring the vfd to the breakout board like the attached file?

If both of these are correct then you can in fact use the port 2 outputs for this. I think the confusion comes in when you go to the ports and pins page and configure the m03 (fwd) and m04(rev) wires. It says you must use outputs 1-6. This doesn't mean pins 1-6.
You will normally use output 1 for fwd and output 2 for rev.
Then go to the outputs signal page and assign them to port 2 using the pins that you have them wired to.

Let me know if this helps.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

Yes, on both questions.  I was wondering about the mach3 settings, and that helps.  I'll give it a shot.
