Connecting ASDA-B2 delta servo driver to AXBB

[KlausLim]

I must say right away that I'm just getting started, so I apologize for the mistakes.
I'll try to explain as clearly as possible.
I have a few fundamental questions about connecting a serv.
In the machine, I will have 4 servos for 3 axis + 4th axis.

I'm going to connect via step-dir (base number of wires).
Pul +, Pul-, Dir +, Dir-, and also probably the motor Enable.

Question 1: Will I have enough pins for the servo to work correctly?

On the forum, I found the Delta topic and there in the comments a person cited his variant as an example:
"24V EXT - COM+ (11)
COM+ (11) - PULLHI (35)
GND EXT-COM- (14)
/PULSE (41) - O2 | [Step]
/SIGN (37) - O3 | [dir]
DI1-(9) SON-O4 | [Motor Enable]
DI5-(33)ARST-O5 | [motor clear]
DO5- (27) ALRM - Ix-endstop
e-stop alone goes to another spare pin"
As you can see, it has more pins involved.

Question 2 (most important): How do I connect all this amount of wires to AXBB, there are not enough outputs?

For my build, I bought axbb and a breakout board for the 4th axis.
And I would like to put 4 motors for 3 axles on AXBB, if possible without using a breakout board.
But for example, Port1 has only 17 outputs, which is not enough in theory.

Question 3: What type of connector goes to Port3?
Thanks

What type of connector goes to Port3?

An IDC26 cable. The AXBB manual explains this.
You're most likely going to need to add a breakout board to port 3, and you still may not have enough inputs.
You'd have been better off with a UC300ETH, imo.
I'm using a UC300ETH with a UB1 breakout board for a machine with 4 servos. Very simple to wire up the servo drives to the UB1, which has separate terminals for each drive.

But why do i need so many inputs. For servos i need outputs.

Encoder and Fault triggers.

With my Lichuan A4 AC servo drive (spindle motor) it has 4 outputs for the encoder and 6 outputs for various fault triggers.
So if all are used, that will require 10 inputs on the controller!.

You CAN wire the fault switches into other parts of the system via relays/optocouplers etc and daisy chain them so you can use less controller inputs. That adds to costs and wiring though.

I opted to go the UC300eth route with mine. I couldn't afford the UB1 so I use some cheap optocoupler modules. They wire directly to my controller at 5v and then to my controls at 24v. So 24v>5v on inputs and 5v>24v on outputs.

So how many wires do you have going from the driver to the controller?
