Brains to control a mitsubishi VFD - FR D700
« on: June 20, 2014, 01:33:35 PM »
I'm battling for a week with brains and modbus registers... Have learned some things but not enough to get a working brains. all I need is some help configuring the brains in a way that I can write "2" on holding register at address 40009 or offset 8. It will turn on the spindle cw. on modbus test I can get it work as you can see at the images. Any help is appreciated.

After trial and error, came out a brains that is working as I wanted. Will post it for somebody that needs it. It's for a fr-d720 but is the same for almost all mitsubishi drivers, I believe... good luck.
