Do you mean 'modpoll the proper registers' to mean 'read several holding
registers in one operation'?
If so: I had that problem with the Toshiba VFS-11. See the note in my

It seems I'm missing something obvious. I thought the idea was to move
the motor back forth while comparing the commanded (presumably, the

Is it possible that you have some binding or tracking issues? The 7I39L has
a current limit of 15A/phase If you exceed ths current, you will suddenly
have a drastic change in your tuning as you will lose the inherent damping
of a voltage mode drive.
All this talk of lowering the servo thread had me thinking back to when
I was setting up the KT. I wanted to try to lower the servo thread for
testing. I could not go much slower the the 1ms default or I would get
real time delays. After some consultation on irc - it was decided that

I haven't considered a generic VFD or Modbus device driver, because not
only do the device functions vary widely, but so do implementations of the
Modbus standard.
Yes, I found that too. I built my code based on the GS2 module and
Michael's code.
Early on, I avoided using the GS2

Greetings;
Since I made the top side of a board look pretty good, but got stymied by
linuxcnc's refusal to do a move to tool change from .1 to Z6.0 when it had
8.5 of room, I figured I would play with pcb-gcode see if I could do the
