Title: Delta VFD control from Mach
Post by: dwilliams56 on November 03, 2011, 09:44:59 AM

I have a Delta VFD022B21A that I want to control from Mach3.

What do I need? 

Any one know what I can get the remote control for this unit?

Thanks,
Don Williams

Hi Don,

Welcome to the forum.

The VFD requires a 0 - 10 Volt dc source to control the speed and Mach has a PWM output intended for operating a VFD.
You need a controller board to convert the PWM signal to the 0 - 10V such as this http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=303 which also has the on/off - forward/reverse relays.

Hi Don

Have you see my VSC?

If you wont I give you the schematic to build yourself.

If you wont to see it this is my web www.robotfactory.it

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?

Hi Andrea, I would be interested in the schematic, if possible.

Hi Don,

You need to check with your VFD instructions but selecting US Mode on the C41,  I would connect both V-IN together and connect these to VFD terminal SD   then relay #1 terminal NO to VFD terminal STF   and relay #2 terminal NO to VFD terminal STR.

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...
