My name is Merik.
I have an IRB2000 S3 robot and can’t get it working.
I have done the following fault finding and repairs so far:
I have replaced the tantalum capacitor that was blown up on the main computer board and fixed the pcb.
I have only the computer, 6 axis cards and safety card installed at this stage.
I have replaced the nicad battery.
I replaced all the electrolytic caps in the power supply and voltages and ripple look fine.
I replaced the capacitors on the safety card.
The unit still gives me the following and nothing more when I connect a PC serial terminal on the sensor port at 1200 baud:
560 ERROR / ROBOT COMPUTER 0130 00
And the teach unit displays PROG UNIT COMMUNICATION FAULT
Any help for next step fault finding would be appreciated.
