Lube logic and Parameter 179 are standard to nearly every Centroid PLC program of the last 20 years.

If you install a fresh version; assign "LubeOut" to OUT1 as before; and set Parameter 179 to the same setting you had previously (or check the same boxes in the Wizard), then it will work just like ...

First, the lubrication is kicked off when I press the cycle start. I can see it by pressing CTRL+I and viewing the output (in my case, output 1). Where can i find the piece of code that trigger the Lub when i cycle start?

I answered your question above, but I did not ask the obvious followup ...

"OUTPUT5", "OUTPUT7" and "OUTPUT8" and similar names are generic output functions that Centroid provides, for when you want to control something that is not otherwise supported by the PLC program. They are controlled with the M61-M68 and M81-M88 M functions.

Since you do not have any wires ...

In a typical Acorn PLC program, a "ToolUnclampButton" input is used with an "UnclampTool" output. Since you do not have any output assigned as "UnclampTool", your tool unclamp button will not do anything.

If one of your outputs is wired to a solenoid valve that unclamps the tool in the spindle ...

That sounds like a power polarity / encoder direction mismatch. Try swapping your plus and minus motor power leads.

As far as I know, the factory cables work just fine with ASDA-A2 drives.

Can you point out the particular pin connections that you think are wrong?

Note that the ASDA-A2 drives apparently have two sets of "pulse" and "sign" inputs. It appears that Syntec was using the "low speed optical coupler ...

Looks good!

; Control ToolSetterArmDown (OUT19) with Aux3Key_M (push and hold)
; At the start of every check ensure ToolSetterArmDown is deactivated and reset.
IF TRUE THEN RST ToolSetterArmDown
IF TRUE THEN RST ToolSetterArmDownActive_M
IF TRUE THEN RST Aux3LED

; Make sure up and down can't be active at the ...

I am curious why it is better to set OtherFault_M rather than set SV_Stop directly?

Review the section in MainStage under the "Handle Faults" comment.

If none of the fault categories are set -- PLCFault_M, SV_STALL_ERROR, SpindleFault_M, LubeFault_M, AxisFault_M, ProbeFault_M, OtherFault_M or ...

Your screen pictures above clearly show that the M3 macro and PLC program are doing everything they can and should do, to make the spindle start and run. OUT7 "SpindleEnableOut_O" is on (green), and W7 "SixteenBitSpeed_W" is 16383, which is essentially 25% of maximum speed.

Either there is ...
