I feel like it and I'm bored, my new project: M2000 and 7+8 axis

First I would like to introduce my system.

I got a system that had 3 external axes.
A motor is defective and I only want to operate 2 external axes.
Everything is in the controller cabinet, no external control cabinet
An extension of the connector board and a 2nd SMB are mounted in the cabinet.
The system also had a welding option and a SIB board. I removed all of that.

I can boot the robot alone without any problems. Can I still load the axes later?
Or do I absolutely have to boot SERVICE?
What exactly does SERVICE booting do?

I also have a backup of the old system with 3 axes, but not everything is listed in the *.moc parameters. There is probably a lot hidden and not included in the backup.

My plan now is to boot the Robot solo with SERVICE and add the two external joints.

I still have to rewire some things in the control cabinet

One question still remains open for me:

Which channel do I have to use on the SMB board?

In the meantime I looked at the cfg files.
M7C1B2.cfg....M8C1B2.cfg to M12C1B2.cfg

i found this inside:

MEASUREMENT_CHANNEL:
#
-name "M7C1B2" -use_measurement_board_type "DSQC313" -measurement_system 1\
-board_position 1 -measurement_node 1

In my opinion it could be this value. only this value is changing
-measurement_node 1 ...2 to 6

Today I'm changing the wiring, maybe I'll get to the test.

The wiring has now been changed.
After making some changes to the moc, the system boots up without any errors.

But:

I still can't move the axis. I get torque and collision errors.

The engine data is probably not correct yet.

I need the correct unencrypted data for an MTC750.

Where can I get the correct data?

What surprises me is that the axle doesn't move at all. 

I'll check the wiring again. right motor, right brake, right resolver

I'm still looking for an S4c+ M2000 option disk with an L positioner 750KG

Do I have to specify a load somewhere for the axis?

Update:
one axis is running
The problem lies in the use of the driver units.
I (think) can't operate 2 MTC750s on a DSQC 346U.
one axis runs on node 2.

The other axis must be connected to the rectifier drive unit.
this can also deliver 55A.

tommorow i will test again

i will modify this section

DRIVE_UNIT:

-name "M7C1B2" -use_drive_unit_type "DSQC_346U" \
-use_current_controller "c_c_fast_1" -use_drive_unit_supervision "d_u_sup" \
-drive_system 1 -unit_position 1 -node 2 -i_max 55 -i_thermal 24 \
-temp_ambient_rise_transistor 2
# -name "M8C1B2" -use_drive_unit_type "DSQC_358G"\ -use_current_controller "c_c_fast_1" -use_drive_unit_supervision "d_u_sup"\ -drive_system 1 -unit_position 0 -node 2 -i_max 55 -i_thermal 24\ -temp_ambient_rise_transistor 2

Attached is the MTD750 i found. Hope it helps.

OK and thank you
It's not M2000 but the control parameters are good

This is my new plan

Both axis are now moving, but I had to change the configuration again.
The 2 external axes are now connected to the same unit at location A3/Node2.
The same entries are available for both axes under Drive Unit.
I can now activate A7 or A8. The system does the switching itself. If I activate A8, A7 is automatically deactivated.
But I can live quite well with this solution.

I didn't manage to connect A7 to the rectifier and A8 to drive unit A3. I kept getting errors from the measuring system.

I guess:
It is not possible to connect the SMB to Connector Board 2 and the drive unit to Connector Board1. The axis was then connected to two different axis computers.
