Padovani LE-200 Retrofit

Yay we have a new project

Bought myself a Padovani Teachin lathe
The machine is still in the shipping company
have so far only pictures.
Wanted to make it similar to the Maho,
and leave the original electrics as original as possible.

The machine has Siemens drives.
can you tell from the photos what they have for inputs?
+/-10V?

or are they already connected to a bus or something?

slowly it will start .

Yesterday I set up the future computer.
After your positive mention of the series here in the forum, I bought a used HP 8300.

It showed good latency values right away, without any further hacks.
 

I already have a 7i92 here,
Now I have to study the circuit diagrams to see which cards I still need.


have just unloaded the lathe here
Everything looks good so far.

But first I have to sort everything out and set up the lathe in the workshop.

Hmmm, I have looked through the manuals and file folders.
A wiring diagram of the electrics seems to be missing
would probably have been too easy.

In the appendix some more designations.
of the installed control system and drivers.

 

sorry for the poor picture quality

was quite dark and the mobile phone battery too empty for a flash

to start somewhere

this pdf describes the interfaces of the shoring control system.
If I see this correctly, the machine really seems to have normal +-10V with encoder or glass scale feedback.

That would be already good
Outputs 24VDC, whether as sinking or sourcing I have to look yet



 

Connected to the central unit are the +-10V encoders and right PLC outputs as well as inputs, 24VDC.
 

The task of the so-called MPC module is unclear to me.
It is connected to the central unit via a serial data line.
Placed left next to the servo drives, 6FX1142-2BA02.

It also has many inputs and outputs, which are also connected.

Is the emergency stop chain possibly monitored with it?
Or hardware limit switches?

 

Since I don't have a wiring diagram for the lathe, I traced the path of the power current into the machine yesterday,
Some things are now clear, much is not yet
But will become already...

What I would like to do now.

I would like to trace the complete wiring of the Siemens servo drivers, and understand it.
So I can test the servos with a small variable voltage source and without belts.

Once the servos run, I can remove the existing control system


Unfortunately I have not found any manuals for the Siemens servo drivers so far

With the pdf from radom I could now assign all connected terminals of the Simodive.

I am still unclear about the meaning of the individual enable connections on the spindle driver.
There we have a so called

"pulse enable" (663) and a
"controller enable" (65)

both separately switched via a relay.
and both refer only to the spindle motor.

Furthermore an input E4, also switched with a relay.
Freely programmable according to the manual.
