Maho 500 W4 Retrofit was created by T_D
Hallo zusammen , ich bin seid ca. 4 Wochen der stolze Besitzer einer Maho 500 W4 , es ist die selbe wie in dem User DoWerna jedoch haben sich bei dem Eintrag nicht alle meine fragen geklärt , zum einen wie ist das mit den Mesa karten gibt es unterschiede zwischen PCIe oder über Lan Kabel bzw. was ist besser oder besser erweiterbar oder eventuell günstiger und wie ist das mit dem Bedienpult welches ich selber bauen möchte ? ich habe mir die benötigten Taster zusammengeschrieben und möchte das auch in der Art machen mit Gmoccapy und dachte an die selbe Bedienart wie bei den Kunzmann 3/4 Maschinen dass dort also noch ein Handrad mit Achsauswahl hinzugefügt werden soll (Haidenhain Steuerung). ich bin kein Elektroniker sondern Industriemechaniker und muss mich dort in das Thema selber hineinarbeiten deswegen wäre die ein oder andere Hilfe gerade was die Mesa karten angeht nicht so schlecht ich mache gerade einen Maschinenbautechniker und kenne mich dadurch schon ein wenig mit SPS aus aber manche Sachen kann man dort übertragen aber gerade das mit diesen Signalen bzw. von Haidenhain Glasmessstäben zu denen die die Mesa versteht ist für mich Neuland . gruß Tom

Assuming it has analog servo drives and those work, you would need an analog Mesa card, preferably Mesa 7i97T as it has analog outputs and encoder inputs all on one card, and a few I/O for limits and relays.
It is an ethernet board, and there is no practical difference between PCI/PCI-E/ETH cards except ETH cards can be mounted wherever is suitable on the machine as the LAN cable can be quite long, while DB25 cables are limited to about 1.5m (there are 3m and 5m ones but will have to be very good quality to work).

The Maho should (or should not?) have some EXE boards that translate the signal from motor feedback to encoder pulses that Mesa can use. This is what i've learned fro reading here on the forum, i do not have a Maho.

Hi Tom, I did my 400E with Mesa 5i25 (PCI), 7i77, and 7i84, but back then the 7i97 did not yet exist.
If I were starting again, I would use the 7i97 and 7i84. I hard wired everything in my Bedienpul. Today I would use a 7i73 to interface that.
Does your 400W4 still have the 18 speed gearbox, or does it use a big DC servo on the spindle with just a back gearbox?
I would also suggest you take a look at Peter (Talla83 on Youtube's) Pendant.
Peter hat die beste Mesa Info auf DE.
Cheers,
Mark
