General Mach Discussion / Re: Delta VFD control from Mach
« on: December 01, 2011, 01:37:53 PM »
Thanks Tweakie.

I finally got the folks I bought the machine from to help me.  I selected US Mode on the C41.  V-IN connected together and connect these to VFD terminal DCM (digital common)  then relay #1 terminal NO to VFD terminal FWD and relay #2 terminal NO to VFD terminal REV.  I then changed a couple of VFD parameters.

It seems to work!  I can't get too excited yet. But, this is progress...

The C41 has two relays with the connectors labeled NO V_IN NC.  Will the V_IN connect to 24V from the VFD?  Then the NO connectors connect to FWD/REV?

Does your g-code have a G21 in it? I'm pretty sure it's a units issue. Probably opposite what I said before. Machine set up in inches, and running a file in mm's.

Gerry you and Tweakie are right!

My machine was motor tune in MM... If I put a G21 in my code I can run my files:)

What do I need to be aware of to change the motor tuning to inches??

Thanks for your quick help!

>>How do I check my native units

Never mind I found it in motor tuning.

Gerry I have G20 in my Mach init string.

How do I check my native units?  This is a new machine (K2CNC).  The only software I received was the Mach profile.

Units don't matter. The movement of the DRO doesn't relate to the movement of the spindle.  Large movement of the spindle small change in DRO.

I tried a couple different files with same result.

Yes. That is one of the first things I thought of too.  But, the movement of the DRO has no relation to the movement of an axis.

Inches or MM makes no difference

Thanks for looking,
Don

I fire up my router and do a ref all everything appears normal.

I jog an axis one inch and the spindle moves one inch. 

BUT, if I load a file then all three DROs move to a seemingly random location.  If I then move the spindle 1 or 2 inches the DRO only moves by some small amount, say .06 or something.

So if I try to move the Z axis 4 or 5 inches the Z hits the stop long before the Z axis DRO gets to 0.75in.

Anyone have any clues??

Thanks,
Don
