Did you try turning off the encoder digital filter?

setp hm2_7i76e.0.encoder.XX.filter false

(Where XX is the spindle encoder channel)

There's probably  a:

setp hm2_7i76e.0.encoder.XX.filter true

already in your hal file

This is described in the hostmot2 manual (in the encoder section)

We've re-adjusted our wiring as you showed in your previous message but we still don't understand how you got to the 24000 for the MaxOutput and 28800 for your output scale, is this a set value or is there a way to calculate the 24000.
In the Pncconf we're also clueless as to what the value should be for "encoder scale" .
The spindle can't spin in reverse, and the "rev" light on the VFD doesn't light up either when we put it in reverse, do you think this has something to do with the configuration of the VFD or is it something we have to resolve through the INI file.
Thanks in advance.

Hello folks,

I am facing the problem with loosing velocity value from Mesa 7i77 card which is plugged to P1 of Mesa 7i76e. I have tried each channel of board and each are behavior same same... Encoder is Heidenhain quadrate full TTL 5000 increments per rev means 4*5000 = 20000 in encoder resolution... When the spindle speed rised over 1500rpm(equals ((1500/60) * 20000) = 0,5MHz), velocity feedback in encoder component of 7i76e is disappearing and thats all.. I checked wiring and shielding the cables. Each cable have separate shielding connected to the ground....

I am think there should be problem with encoder limit frequency. I can not find any informations about this limitation in the any Mesa manual. I there any limitation setup in the mesa ?

thanks for any suggestions

Hi again    
I have my 1.8KW AC servo motor up and running on LCNC 2.9.2 with Dragon UI.
It runs in both directions and working just fine but I want to do the following and need some helt
to direct me to the correct hal/ini setings to tweak.
1. I plan to use a 2 speed belt drive how do I change gearing.
2. I plan to use an encoder on the spindle shaft to get spindle positioning and homing for tool change.
Is this possible to achive in pnconf (I use #5 Step/dir on my 7i76E configured as spindle in pnconf) or should I
configure the servo as an axis to be able to do this?

Kind regards/Stefan 

Hallo Ich habe ein Problem mit meiner Ethernet  Verbindung  zwischen Pc und Mesa  7i76e
Wen ich Linuxcnc starte und einen Ping 10.10.10.10 ist alles in Ordnung.
Starte Ich Linuxcnc Axsis komme ich bis zur Reverencfahrt danach bricht meine Ethernet Verbindung zusammen.
Ich habe einen Zotac Mini PC mit 2 Ethernet Schnittstellen und 1 mal Wlan, Ich habe eine Ethernet Ausgang
abgeschaltet. Realtek RTL 811
Frage wo ist der Fehler

Andy also explains it here:
forum.linuxcnc.org/27-driver-boards/3537...to-mesa-7i76e#119013

The VFD provides an isolated GND (ACM = analog common) and 10V output (preferred) to the Mesa card (Spindle- / Spindle+). Spindle out is a potentiometer, like you said. 
In this case the input voltage is 12V and that needs to be scaled down to 0-10V. This happens in your INI.
Take GND also from the analog section. 

Enable and direction are isolated outputs allow sinking, sourcing combinations of both. Most chinese vfd are NPN inputs - you need to provide GND (DCM = digital common) to their input to close the circuit. 

You take the GND from the vfd and connect it to SPINDLE ENA- and from SPINDLE ENA+ back to your VFD (input). That way you are providing GND to the VFD input, when the relay is on. Same for the direction.

Most VFD's have ACM (analog common) and DCM (digital common) but I couldn't see that in the A2 manual. 

SPINDLE ENA- <-> VFD GND
SPINDLE ENA+ <-> VFD FWD/RUN

Say your inputs are PNP (24v)...this would require a 24V signal. You would take 24V from the VFD to Spindle ENA+ and back to the VFD on SPINDLE ENA- to your input. 



 

the wiring is was given  on  "forum.linuxcnc.org/27-driver-boards/3537...mesa-7i76e#gallery-4"
if i understend it correkt   the vfd give power to the mesa card  for the spindle output
on tb4 pin1 and pin 3 are the powersuply for the analoge out of the mesa card  and the vfd provide these  power
while pin 2 is the real voltage output   
the mesa  card act as an potentiometer ?
pin  6 and  8 had also 12 / 24 v this is also power deliverd from the vfd 
this is very confiusing   witch pin is input and witch is output   on the mesa card  and on the vfd  
same problem for the dir and enable pin  here the vfd give power  and the  mesa card act like a switch ?
 

Did you wire it correctly? Can you share your wiring diagram?

The Mesa 7i76e doesn't provide 0-10V by itself. You need to provide 0 - 15V (max) to SPINDLE- / SPINDLE+. The SPINDLE OUT needs to be scaled in your INI based on that voltage. 

Example with 12V to create a 0-10V output

[SPINDLE_0]
# 0-10V output based on 12V input
MAX_OUTPUT = 24000
# 12V = 28800 rpm / 10V = 24000
OUTPUT_SCALE = 28800

Wiring:
Mesa 7i76e:
SPINDLE-  <-> VFD GND            
SPINDLE OUT <-> 10V_IN
SPINDLE+ <-> VFD 12V OUT
SPINDLE ENA- <-> VFD GND
SPINDLE ENA+ <-> VFD FWD/RUN

Optional:
SPINDLE DIR- <-> VFD GND
SPINDLE DIR+ <-> VFD REV

Hi sorry for our late reply, this is what showed up when we typed in the command in terminal.
We also measured 0V between pin 1 and pin 3 when the spindle was supposed to be running.

Now i found the reason about working and not working of the Jogwheel of the xhc-whb04b-6.
Its a issue with MESA 7i96S.
MESA 7i76e works without any problems, but with a MESA 7i96S is possible as well.
in a old configuration i found in the Hal ( was for MESA 7i76e ) "[HMOT](CARD0)"
in the new configuration i found "hm2_7i96s"
[HMOT](CARD0) is working in both configurations with the xhc-whb04b-6
i testet in the Linuxcnc Versions 2.8.4 and 2.9.2 .. in both Versions is working
My Configurations was made with Pncconf
The Inputs and outputs is to write in this way for using with 7i96s :
"[HMOT](CARD0).ssr.00.out-02"  for output
"[HMOT](CARD0).inm.00.input-01" for input

My suspect is the issue the driver for the MESA Card 7i96S !
The solution is to change "hm2_7i96s" to "[HMOT](CARD0)" in your Hal

Hello,I am running LinuxCNC (2.72) on a intel pc for some years successful. Now the harddrive on the intel pc is broken and I would like to run LinuxCNC on a RasPi 4.I created the raspi image and I booted the raspi and now I am trying to create the configuration using PNCconf.When I try to finish the X Motor settings I get an error PNCConf encountered an Error ......locale.Error: unsupported locale settingCan anybody help me to fix this problem, so that I can configure my cnc on a raspi 4, please. (I cannot use the config files from the older version, because there are some changes in the config file /s, and I am pretty sure I have to create now config files for version 2.9.2.I am using a Mesa Card 7i76e (which was/is successfully used by my old config)Any help is highly appreciatedBest regards Hartmut
   

Hello Andi,
thank you so much, i know the Video of talla83, this guy is a pretty well teacher of Linuxcnc.
Today i tested a lot of things it different versions of Linuxcnc, and i have a hot suspect of the source of this problem.
With the version 2.8.4. with a configuration of a Mesa 7i76e is working very well, with the same configuration but with a Mesa 7i96S doesnt work the Jogwheel of the xhc-whb04b-6.
I rewritten the configuration by of the Mesa 7i76e to a Mesa 7i96S manually and its working too.
My big suspect is the pncconf program, i am sure here get the Hal a value that prevented to work the xhc-whb04b-6.
Tomorrow i will check something about the values in the hal, because i need to understand the source of the problem.
I will report my experience.
I see, a lot of people here has exactly the same problem.

I haven't done nor tested this but the CIA402 comp should work for your spindle in CSV (velocity mode).

I would probably use Pncconf to generate a test machine with a Mesa 7i76e for example and Spindle StepGen.

Use the test machine HAL to copy out the spindle section, remove the stepgen lines and connect our velocity-cmd and velocity-fb to the CIA402 comp.

Connect and set your Spindle CIA402 to CSV mode.

I might add you can flash the 7i76E with the correct firmware with my Mesa Configuration Tool.
