kawasaki js 010 controller a87 no power on the motors

Good, so now error has moved.

Is other axis operating ok then?

Ok, so this is good.

This proves to me, harnessing is good and also JT4 gearbox is ok too, so you're problem in my opinion is:

1. Motor/brake/encoder assembly.

2. Power Block for JT4.

With robot still in this condition, swap physical motor (take out motor and swap over) in arm between JT4 and JT5 to prove if motor is good/bad.

- If error move to other axis, then motor/brake/encoder problem.

- If still at JT5, then power block problem for JT4.

You will probably need to re-zero axis before make test.

Ok......I am confused now...….

Physical Motor connected to wrist is now configured as JT4, so when you press JT4 buttons, wrist moves yes?

- Does this produce any errors?

Ah ok......yes, I was mixed up.

Yes, it does sound like it could be gearbox then.

I would swap the motors over, and if the error moves, then it is motor, if the error remains, then gearbox.

FINALLY...……………….a result......I am glad as my fingers hurt as they have no skin left on them...………….

Remember, to return all cables again, back to normal......but do not rush, make sure connections are good or we will be back again.

All the manuals I have, I placed here A and AD Controller Documents

Glad to hear.....

We got there in the end...…….Go Team Kawasaki...…

Just out of interest, what is date of manufacture of this JS 30 and also Controller, I would be interested to know?

- Date should be printed on data plate on Controller and on Arm.

No that's fine...….as I say, it was just a matter of interest.

I like to see the old workhorses resurrected and still have plenty of miles left in them:

29 years old, just another example of Kawasaki and their longevity achievements...…………
