Mesa7i96s + 7i85 + pktv2 firmware for Huanyang VFD

Hi all

My retrofit control box is starting to take shape. I use a 7i96s + 7i85 (+7i84D smart serial) card. I would like to use the Mesa modbus  on the 7i96s' smart serial port for Modbus (to control my VFD).

Is there a firmware for that available or can someone compile one for me?

Do you think standard mesa modbus works with Huanyang VFD (since these VFDs don't use proper Modbus)? In the comp file I can only define the registers but not the whole data stream to be sent and received form the vfd.

Cheers,
David

I would think it would be simpler to use a 0-->10V analog spindle speed control
Also, I'm not sure if the Mesa MODBUS interface would work with the Huantyang

Hi PCW. Ok thanks for the reply. This was my backup plan, so I will probably go this route then and leave the modbus stuff for another project.

Cheers,
David
