kawasaki js 010 controller a87 no power on the motors

I'm confused now...…...

After the load, when you power off, you are turning off dipswitch 6 aren't you?

Do you have any 9ZA boards?

9ZA boards in order to function require 4 removable EEPROMS.

These are the 4 chips with labels on them, the label also tells you WHICH location they should be inserted into.

You can swap these around your other 9ZA boards (just making sure the dipswitches are all the same) and try them all out (Just make sure you don't damage them).

The 9ZA is basically the computer part of it all.

The 4 EEPROMS are required as they hold the AS firmware and programs etc.

They also need the 3 batteries installed on them.

9ZA are all the same, except for the EEPROMS and jumpers/dipswitches.

This information is all in the troubleshooting documentation - The link I provided you for these.

The fact you have one robot system with all these boards could well suggest a previously failed attempt at fixing it......and it you may be in possession of faulty items too.

So, by trying to plug and play with them, you may just get it working......but without knowing if ANY are functional or not, I think you need 'lady luck' to be on your side.

Yes, that's an option.

If I was in your position I would have emptied gasoline over it and held a Kawasaki Robotic Sacrificial Party......

9ZA and 1GE are key to getting this going.....

Hmmm...… some nice progression, we can see software version at last.

The error 1420 is because the small card fitted to 1GE (1GM board) is not correct type for Robot Arm being used, change 1GM card to resolve this.

Regarding JS30, it depends on the error code on what could be causing the problem, sounds like brake is worn.

JS30 Joint 2 and Joint 4 motors are not the same are they?
