Frage wegen Spindelencoder an 7i76

Category: Deutsch

If you figure out which input does not work, if you have a voltmeter or just an LED
you can trace the signal at the 7I76's  DB25 connector to see if the issue is with the
7I76 or 7I92.

 

 

Can I plug the 7i92TM directly into the 7i76, i.e. the DB25 connectors into each other? Perhaps the ribbon cable or the connection to the plugs is defective.

I am going through the Drive and the manual to try and figure that out.. From what I have found so far it is all good, but I must be missing something some where. I have an encoder connected back to the 7i77 but not able to see the counts for some reason.

Here is all i have, except the white one, all have been tested and working for various periods of time, from an hour to two days non-stop, all worked just fine with Mesa.

Ethercat installation from repositories - how to step by step

Category: EtherCAT

Update ... 
(After installing LinuxCNC 2.9.3 (Debian 12) and EtherCAT module (Master driver 1.6.2), I am unable to get EtherCAT communication working.  These slave drives work fine with LinuxCNC 2.8.  Something is different in 2.9.3.  What changed?)

However, sometimes one or more slave drives come up in OP state.  When a drive goes to OP, I can see position feedback, I can enable the drive, I can see the DS402 statusword (in drive software).  But it seems to be completely random whether the drives go to OP or PreOP ERROR.  Something must be working for the drives to sometimes go to OP, but I can't figure out what is causing the errors.

With only restarting LinuxCNC multiple times, I get different slaves erroring or going into OP state:

if the step scale is 100000, you should get 1 turn of the shaft for a .1" move
if the drive is set for 10000 steps per turn.

If not, the drives  steps/turn or encoder resolution are probably not set properly
