The drives are 33 years old and the machine was in service till this year on a nearly daily basis. And again. The drives are known for having problems with the tantals. I dont want to have problems later on which I could had easily avoided.

Schema here 
 

Anyone?

One way:

in the main hal file add:


net spindle-vel-rpm hm2_[MESA](BOARD).0.encoder.00.velocity-rpm


in the gui hal file delete:

net spindle.0.revs  => qtpyvcp.spindle-encoder-rpm.in

and add:

net spindle-vel-rpm  => qtpyvcp.spindle-encoder-rpm.in

Hi guys, can't get spindle RPM to display, i have noticed a few different examples in the postgui.hal but non seem to work, i just get a -0 in my rpm display, I will attach my postgui.hal and my main.hal and a screenshot of halshow. Hopefully it's something very basic.thanks in advance

     

Yes, looks like an encoder issue of some kind (especially the sudden drop to 0 velocity)

I would try lowering  the emulated encoder output scale, as
maybe the drive has an issue with quadrature generation at high
speeds and high  resolutions.

Its probably easier to add the step/dir spindle to a MesaCT created configuration.

Can you post your MesaCT created hal/ini/io files?

No more than handful of lines need to be added.
 

I know - it is very unusual as a linuxcnc noob to start with an ethercat setup especially when you are en ethercat noob as well...
but I was so fascinated that I just wanted to give it a try.
Now I am at the point where Linuxcnc is installed, my ethercat is running and I get this terminal output:
0  0:0  OP      +  EK1100 EtherCAT-Koppler (2A E-Bus)
1  0:1  OP      +  EL1088 8Ch. Dig. Input 24V, 3ms, negative
2  0:2  OP      +  EL1008 8K. Dig. Eingang 24V, 3ms
3  0:3  OP      +  EL2008 8K. Dig. Ausgang 24V, 0.5A
4  0:4  OP      +  EL1008 8K. Dig. Eingang 24V, 3ms
5  0:5  OP      +  EL2008 8K. Dig. Ausgang 24V, 0.5A
6  0:6  SAFEOP  E  AS715N_sAxis_V0.10
7  0:7  SAFEOP  E  AS715N_sAxis_V0.10
8  0:8  SAFEOP  E  AS715N_sAxis_V0.10

As servos I use 3x Stepperonline OMC a6 400W

Now I tried to figure out how to build a working xml and a corresponding hal file.
After several hours of reading try`ll and error my last hope is that somebody of you would be so kind to share its xml and hal (best with running a6 servos) file so that I have a starting point for my setup.

Any help or hint is highly appreciated!

One: as you said... puff
Two: smd caps is faster to replace. I have to change nearly 30 caps each driver. So 90 in total.

When clipping the old one and soldering the smd on the other side directly on/over the drilled holes its a damn fast way. Cleaning the holes, soldering tantals in, clipping the wires taked more time...

So mainly cause I am lazy. And tantals costs (in comparable quality at my normal suppliers) round about 15 to 20 euros more than smd ceramics.
