Ex Mitsubishi Australia FA20N Inputs/Outputs cut

[jgmell]

Hi folks,
  I bought a second hand FA20N robot with a C controller from Mitsubishi Australia when they took their bat and ball and went home. 
They have cut all the input and output cables just outside the control cabinet. I know that stacks of these things got sold in Australia so was wondering if anyone has gone through this and has any wiring diagrams, or helpful hints, etc.

Although they're for the D controller, the I/O connections can't be all that different.

We also purhcased a couple of FA20N from Mitsubishi's.  I have managed to get the robot up and running but can't get it to communicate to the welder - our robots have Mig welding equipment attached to them.  My advice is to make an immediate backup of of the robot files, before you initialise the machine, if you are going to do that.  I did not and think this is why I am having trouble.  Is your machine a welding robot? I assume it is being an FA20N. 

I removed all the I/O wires connected to the onboard PLC as they will probably only be suitable for interfacing with hardware at the Mitsi factory.  These should be loacted on the controller door.  There is also an internal safety circuit connected to TB2 (terminal board 2).  Do you have the installation manual for the robot?  If so you should be able to work out what these are for, e.g safety fence, external interlocks etc.  I have bypassed some of these in order to get the robot moving - have to be careful here in regards to OHS and AS requirements when running machine in production, but I just wanted to have a play with it.  I could go on and on about troubles I have had trying to get the machine up and running.  There will be robot integrators out there who have worked on these machines at Mitsubishis who can help you, but it will cost - watch out for sharks. Send me a message if you'd like to give me a call, as I believe we might be able to help each other - we are just a small manufacturing firm trying to modernise and stay competetive with overseas manufacturers.  Also make sure you keep it plugged in with the power point on or the batteries will run out and it will lose all data - this happenned to our other FA20N.
 
Cheers Chris

Thanks Chris,
 That's all good stuff. 
Yep, mine is a welding robot.
I've got all the manuals from the Kawasaki USA website.
I will send you a message, it sounds like your a fair bit further down the track than me.
I've also go some wiring diagrams from WIA who made the welder interfaces.  Mine is an AM284-0 (I think! I'm at home now but will update you when I can).  Your welcome to this stuff if you want it.

We are also a small firm trying to keep the chinese wolves from our door!

Hi there was reading your posts and wondered if you guys were in Australia I also got myself a robot   we are a small fabrication business in Central Victoria . There is a lot to learn . Reading your comments reminds me of many of the same experiences cheers Trev

Trev,
  We sure are.
Chris is just North of Adelaide and I'm in Sydney.

Any help would be appreciated.  Particularly with the IO's (what wire does what).
Also, we both got flat batteries and all the memory has gone so if we can have a copy of the files from your machine that would be a huge help.

Regards and Thanks

John

Hi there Chris and John . Sorry I may not be that much help the robot i got is a Fanuc however i also had back up battery trouble and was able to get software to run as far as i can figure the back
up battery saves mastering settings and arm calibrations the core software should be still intact . One thing that gave me heaps of grief to start with was the manuals that i had were American and the voltages for testing purposes were not correct  as the transformer in my unit had been converted to 415 vac for our power supply so keep in mind when trouble shooting that the books you have are for the same robot model Good to know there are more novices like myself learning from scratch Keep in touch Regards Trev.
