Mesa 7i96s - connectiong spindle controll

Hi,I
have (According to note I was given by the guy who put together control for my CNC) 3 cables connected to Mesa 7i96S TB2 terminals 22, 23, 24.T

his according to meas manual are
Spindle -
Spindle OUT
Spindle +

Now I am struggling how to connect those to my inverter for the spindle.O have Googrive 20-EU 7.5kW Manual www.espacemoteurs.com/catalogue/V-MANUEL-GD20.pdf (to big to attache)

Can someone please advise.

KM 

Spindle -       -->   GND
Spindle OUT  -->   A12
Spindle +      --> +10V

Out4A   --> S1
Out5A   --> S2

Out4B,Out5B  -->  Depends on whether you are using PNP or NPN wiring

how is PNP and NPN different? (And what they are in principle)?

KM

Also Out4AB and Out5AB are not connected on meas board.
Is this a problem?

KM

They need to be connected or the outputs will not work

NPN are sinking outputs so if you wire the drives PW pin to +24V
you would wire OUT4B and OUT4A to the drives COM terminal.

Note that there are schematics of NPN and PNP mode connections on
page 21 of the drive manual.
 

OK,
I am not getting it that fast.

So it seems (to me) that currently I have connected analog 10V signal from mesa to inverter from TB2 22,23,24

But I am missing Spindle forward/Reverse signals.
Those would be OUT4 and OUT5.
I can easily rewire some spare lines from cable I already have, so no problem here.

But I do not get if I am to get 24V from mesa or from other source.

And I still do not get the difference between NPN and PNP.
I do not fully understand schematics you mention.
Also I do not get how Out4A and out4B are related (I assume they are connected together through somethings (transistor or relay) I guess?

I do not know what kind of transistor there is on mesa board (if this sentence have any sense).

I have very little background in electronics. I mostly deal with mechanics.
So really need some help here as I do not want to burn any of my devices.

KM

The 4A,4B5A,5B outputs are from a solid state relay
when output4 is on, Out4A is connected to Out4B
so basically a switch.

The drive itself supplies 24V for input operation.

In fact if you are unsure about the drive connections
you might wire up mechanical switches to the S1 and S2
inputs and verify operation before transferring the connections
to the 7I96S (outputs 4 and 5 behave identically to mechanical switches)
 

So in fact it should not matter if I select PNP or PNP wiring scheme, as 4AB switch is jest a switch controlled by mesa.

PNP wiring scheme from inverter manual I understand.

KM

No, NPN or PNP does not matter as long as you connect the drive  PW and COM
pins properly. This is especially true of 7I96s outputs 4 and 5 since they are not
polarized. If you use outputs 0..3, NPN or PNP are fine but you must observe the
output SSR polarity.

OK,
I think I have it working.

After connecting all wires and running config wizard it seems to work.

At least inverter reacts to signals from AXIS roughly as expected.

But run in to another problem , now residual current protection is triggering.
But this I know how to deal with.
