Dear ABB Gurus,

Greetings from Australia!

A friend and I, both in the fiberglass business, recently picked up an ABB IRB 4400 M97A for an incredibly low price. We’ve wired it up and powered it on, but we’ve hit a roadblock. I have some experience with IRC5 models, but this is my first time working with an S4C controller.

I’ve attached as many details as possible, including images and system information, to this post.

### Current Situation:- Controller Type: S4C

- RobotWare Version (Suspected): 3.0
- Status: The system is asking for the key disc and to press any key.
- Issue: I don’t have the key disc.

### Timeline of Events:1. First Boot-Up:

- Warm Start – Notified of Battery 2 low (I believe).

- Then, an error screen appeared with:

- This issue seems similar to the one in this thread:  
[https://forums.robotstudio.com/discussion/12888/abb-1400-problem](https://forums.robotstudio.com/discussion/12888/abb-1400-problem)

1. Battery Swap Attempt:

2. Subsequent Attempts:

### What I’m Looking For:- Key Disc (or files needed to recreate one).

- RobotWare 3.0 or compatible version to reinstall.
- Any guidance on data recovery or alternative solutions.
- If you’re in Australia and have resources, let’s chat! My number is 0451 733 537.

### Hardware I’ve Ordered:- USB-to-Floppy Drive (to attempt recovery).

- New Batteries (to replace the dead ones).

* * *

### Robot & Controller Details:- Robot Model: ABB IRB 4400 M97A

- Robot Version: IRB4400/1.95-60
- Serial Number: 44-05332
- Manufacturing Date: 1998-01-29
- Load Capacity: 60 kg
- Power Requirement: 3-Phase 400V, 50-60Hz, 7.2 kVA
- Controller Type: ABB S4C

Any help would be greatly appreciated.

Kind Regards,

Tyler White

Hi Mate

I am Vaishnav Kuriyakattil and i am currently working on IRB6400 Robot, as it is an old one i cannot connect it to my pc ,so the only way i think is through teach pendant, so when i turned it on, it was showing guard stop state, and axis not commutated, and it was showing to replace the robot computer or serial measurement board, and when i was checking the voltage of 3.2v battery, i accidentally took the positive wire from it, so now in the teach pendant it is showing to insert the boot disk(1),  
so i dont have the boot disks with me, so if you have could you please sent me the disk, it is really important.

So is there any way i can communicate with the robot?

my mail id is [vaishnavk7799@gmail.com](mailto:vaishnavk7799@gmail.com)
