This has actually been a question for me for about a year....now that I have that valuable piece of Intel that they are most likely +/- 10 analog I might be able to get em to do their thing that...

Thanks very much for you alls input....Ive decided my best option in further thinking is the stmbl open source servo drive ....I've heard the retrofit horror stories and I'm still determined to give...

Hi so I have an old gmf p-150 robot I'm trying to retrofit. Most of the RF controller works but the CPU board has crapped out...I'm trying to use the old vcus before I get all new drives the command...

Ok so i powered up the system....namely through bypassing the damn safety board again...the leds denote as follows main cpu leds read power on reset status, and cpu sub halt. Main buffer pcb has...

So havent had a chance to repower it up yet but i have figured out a number of things from looking around in the controller and from reading the manual quite a bit..
The robot has an internal purge...

Its only ever been plugged into 3 phase mains no rpc. The crt has power, the filament heats up but it displays nothing no static no glow just blank....all boards power up the teach pendant says its...

Hey so my fanuc robots power settings on the taps are specified as accepting said voltages +/- 10% . I know rpcs are subject to voltage fluctuations. Such fluctuations i have read can muck things up...

Yes i measured the voltages from the power supply and all checked out...i believe the bubble memory unit is fanuc ill have to double check...ive only been able to plug it in at my families facility i...

Yes it has the bubble memory board which is held by battery backup, i believe that is just for user programs profiles etc though. All the power supplies seem to be functioning i have over ridden all...

HI so i have an old as original sin GMF p-150 robot with an rh karel controller that ive been trying to get to work.Im probably going to retrofit it for fun bust im trying to see if i can get the old...

Obviously i have much to learn about about encoder signal architecture.....thanks yall for pointing me in the right direction.

Ok kewl....so are fanuc A,B,Z encoders just regular quadrature architecture? Thank you all very much for your correspondence

I am quite interested where do i find this firmware....im looking to use stmbl open source drives with mesa interface.....the developers have a,b,z fanuc encoders compatible but i have yet to find...

Fantastic thanks, do you have a data sheet or do you just know this? Are the two request and data signals the same or are they out of phase with one another?

Hi so i have a fanuc p-155 robot that i want to retrofit but im having trouble figuring out the encoder signals on the robot pin outs they are listed as 1D, 1*D, 1RQ, and 1*RQ and then of course 5...

So probably not an issue on temp side? The encoders themselves are pretty well sealed and then those are pretty well sealed beneath the redcap...then the robot is nema 1 sch 1 explosive enviornment...

Hi so i have 4 robots i hope to retrofit soon 2 yaskawa YR-up6-a00's and a fanuc p150 and p155. My two yaskwas are in a ventiliated storage container.
