Strategie bei Hurco BMC20 refit / Interfacing the Drives to MESA

wenn dir zuverlässigkeit wichtig ist, hau die alten regler raus! wenn du dich auf diese einrichtest und so ein ding stirbt wirds sehr teuer bis das wieder läuft.
ich finde es einen grossen vorteil bei einem retrofit die alte elektronik rauszuschmeissen und moderne weit günstigere einzubauen. da kann man sich auch mal nen regler als reserve bereit legen damit man schnell reagieren könnte.

So I have to proceed with my BOM

There are so much different options on the MESA side and countless questions about the PC Hardware.

I would prefer a Solution with an industrial Panel PC cheap chinese one and an Ethernet based MESA solution.

I would want to have the ability to drive 4 Axis (the machine has of course only 3) but I want the ability to mount a rotary axis.

And I think its a good Idea to use a PanelPC (with touch hope getting this working) with dual Ethernet and J1900 based
as I read 4GB RAM are fine and dual NIC seems also to be a good choice (1x LAN 1x MESA)

So I want to show you which Items I would pick:

As far as I understand from the MESA side I need an Interface which is capable of 3axis -/+10V plus spindle each one with encoder feedback from the coresponding driver and of course several inputs for all the I/O stuff ATC, Endstops etc.
7I80HD Ethernet Anything I/O card
7I33TA Quad Analog servo interface
7I64 Isolated remote I/O card (probably two of them for general I/O Stuff)

From the PC side things are a bit unclear to me I understand that external non shared memory types would be better but I want a fanless in a box panel PC with stainless steel keybord and touchpad
ALI Panel PC Link
this one doesn't have dual NIC I am already discussing this with the supplier
ALI Keyboard Touchpanel Link

What do you think could this be a suitable setup?

Hallo Siegi,

danke für deinen Input,
ich dachte auch darüber nach die Regler rauszuschmeißen...
Ich habe auch eine Fehlermeldung an einem der Regler anstehen...

Ich würde dann aber gleich alle 3 Achsen Regler samt Motor und Encoder tauschen das wäre auch nicht sooo teuer...
Wahlweise Lichuan 1kW 360$ per Achse für AC Servo mit Encoder und Regler oder eben Leadshine ein bisschen teurer.

Die aktuellen Servos laufen auch alle auf 3phasig 200V ph-ph mit relativ großen Trafos...

Würdest du da auch alles rausrupfen oder nur die Endstufen?

Was sagst du zum Spindel Treiber? Auch gleich ersetzen? Das erscheint mir irgendwie schwieriger??

Vielen Dank für deinen Input!
Andreas

Rather than a 7I80HD and 7I33 I would use a 7I92M and 7I77

Not completely sure if you are asking for hardware recommendations,
For the 7i80HD+7i33TA+7i64, you would also need to add a 7i34 in order to be able to connect the 7i64

But a far less expensive route would be a 7i92 + 7i77 and if you need more digital IO maybe a 7i84. That would give you up to 5 axis + spindle (or 6 without spindle) + 16out + 32in just on the 7i77 and 16out + 32in more if you add the7i84 (The 7i84 could connect directly to the 7i77's Smart Serial port. or you could use another Smart Serial card like the 7i64)
If you need to connect more than 1 Smart Serial card to this combo, you would need to add a 7i74 to the other port on the 7i92.

I agree with PCW and Todd, 7i92 and 7i77 and a 7i84.
It is all you need for the Hurco, although i personally use a 7i70 and 7i71 for inputs and outputs through a 7i74. Overkill i know but i like it and used it on several machines .
I can also check the wiring and take some close up pictures of the wiring as that would make it a lot easier for you.
Basicaly you would have to remove old computer/control and everything on the console, put an STP cable through to the console, mount a computer and monitor in the console, mount MESA stuff in the box behind the machine, wire the drives and the toolchanger control board to Mesa boards, and fire it up !
With a bit of attention you can do it in 2 days! It took me 9 days, 4 to 6 hours a day to do it as i did not have schematics or wiring diagrams.
