Attached is a zipped XLS copy of my setup sheet saved from Gsoft2, see any other problems?

The only other issue that I may have incorrect is parameter P03:20, P03:28 and P03:31.

The Durapulse manual is very helpful and written much better than offshore manuals but, there's a couple of places
in the manual that are a bit confusing. Especially this sentence regarding the braking resistor:

Set P06.01 to 0.0 to disable the over-voltage stall prevention function (connected with braking unit or braking resistor). Use this setting when braking units or braking resistors are connected to the drive.

The ability to program this VFD via software is priceless!

Thanks for the help we got the MPG to fully work after changing the mode to 20 and reconnecting some loose wires.

You would need mode 2 on the 7I76Es I/O section to enable the MPGs:

sserial_port_0=20xxxx

These are the loadrt lines that show up in the main Hal file.
We haven't fully configured the spindle encoder yet, because we were trying to figure out how to move the axis' with the MPG, is it possible that the encoder needs to be fully functional before we can use the MPG for the axis'?

Thanks in advance

setp hm2_7i76e.0.watchdog.timeout_ns 5000000
loadrt pid names=pid.x,pid.y,pid.z,pid.s

In the main hal file, the loadrt line, does it set the board to mode 1 or mode 2?
Same line, does it have number of encoders at anything but 0?
Normally encoder 0 would be the spindle encoder, are you using that for MPG?

Hi, I'm having a similar error code when trying to run LinuxCNC

Note: Using POSIX realtime
".custom.hal:81: Pin 'hm2_7i76e.0.7i76.0.0.enc0.count' does not exist"
3999

(The 3999 number changes everytime we try to start up the program)
This only happens when we use a specific code in our custom.hal to control the axis' with a MPG controller.
We've already checked the field power TB1 (pin 5 +24V pin 8 GND) and when we measure P3 there is a 5V available.
The Custom.Hal we used is below.

loadrt mux8 count=1

Servus miteinander,
vor kurzem hab ich auf kleinanzeigen eine Mesa 7i76 bekommen.
In diesem Beitrag  My 7i76e Connection Sheet#85072 hab ich eine gute Anschlussanleitung gefunden.
Da ich auch Nummer sicher gehen will, damit nix kaputt geht, wollte ich die Community nochmal drüber schauen lassen.
Ich hoffe, dass ich nix falsch angeschlossen habe
 
 
 

Gruß und ein gutes neues Jahr
