What is gs2_vfd ?

ok the vfd is installed and the motor work on Mostly stock setting, no serial yet. my MB have on board serial, i also have a 7i44 card in here is it possible to run gs2_vfd off that card

Please see the response from JT. What I referenced is for a much older VFD. I believe your VFD is much newer, as in the latest technology and therfore you would not want to use gs2_vfd.

The GS23 and GS33 are much newer technology, I believe.

Someone can correct me if I am wrong.

The GS2 and GS3 are 'older technology' than the GS23/33, but a cursory review of the modbus sections in the manuals suggested to me that the gs2_vfd component may work with all three variations.

The thing to do is make a close comparison of the modbus registers for the GS2 and GS23/33.  If they match, gs2_vfd should work.  If they don't, maybe they're close enough that some minor editing would do the trick.

I haven't looked that close as I'm using analog control and setting up modbus to get info back from the VFD is way down on my priority list.  The 0-10v from the VFD to my Mesa card is working just fine for spindle load right now.

ok some info for anyone instrested

turns out the gs20 has a gs2 compatibility mode that turns it in to a gs2 drive

I just got a GS20 drive yesterday as a replacement for my mill but first I have to learn how to configure it for another project.

gsoft2 is great for config, I'm just using FOR and REV commands. I tried to work out the pulse train on the gs20, but it wants 24v pulses and the mesa hardware I have requires um more electronics skill then I have. I considered using the 15 preset frequency via the DI3-6, but got the analog out card working so I think just a basic PID will do all I need.
