hi
i am interesting in LCNC logic - how it work
for situation when LCNC command to axis to move 4" ,
and in case if axis moved only 3" ,for any reason like
1- axis hit obstacle;
2- power wire broke;

question-- how LCNC knows that need E-STOP?

1- axis over load with power and because of that E-STOP ( but this will not
work in case of wire broke - because there is no power over load ...)
2- time go and encoder does not move to where it should go or moves too
slow.
i think that it is encoder signal that tells to LCNC if system ok or need
E-STOP.
y /n?

LCNC does not care what communication between servo motor and drive.
LCNC only care to drive be:
1- analog velocity mode with =/- 10 v;
2-incremental quadracha feed back;

any pack -servo motor+drive - that has such output ok to LCNC.

below 25 pin in my existing drive (LENZE SD 94).

which from existing 25 pin do i need/should to connect to NEW type of
drive?
