Sorry, I want a 25 mm wide weave of a 1mm bead with a 1mm wavelength.

Does anyone know if I can have a 5 cm weave amplitude with a 15m wavelength, or will this upset the math?
Thanks in advance. I appreciate all of you in Robot-Forum

Figured it out thanks. It was the cable out to the resolver. Two conductor shorted, but only in the position as it sits on the machine, Take it off and it tests fine.

Sorry, I left out a vital piece. The robot is a welder, and the problem started when the wire shorted to the robot chassis and started a fire.
I've replaced the cable from the controller, and checked the cable internal to the SMB box, and the one to the resolver. If I replace those two small cables and the resolver, then there's not really much left to be the problem, but I don't want to be wrong again.

I'd appreciate advice on this.
My customer's IRB 2400 M2004 threw this code a few days ago, on the extended axis. I checked connections, and today I replaced the SMB with the updated board and battery, not the same units that came out, but ABB assures me of their compatibility. I also replaced the network node on the SMB, and the cable to the controller. I fired it up, calibrated, updated the counter, and it threw the same error. So, I think I should have replaced the resolver too, but I want to test it first. I could swap it with a robot axis, and I could check the voltages if I had the pinout. Does anyone have any other suggestions?
Thank you

Hi Everyone,
I've found some references to my problem in the topic M-410iB Greasing, but no solutions. A customer called after messing up their robot about a week ago, although it is still in service. The worker did the lubrication mostly right, but admitted that,
a) He used a pneumatic grease pump at full facility pressure.
b) He replaced the outlet plug immediately after filling, and before circulating grease.
c) He pumped until fresh grease emerged, but did not keep the old grease or measure the amount removed or filled.
d) The lubrication was overdue by an unknown time, and the grease was black and smelled burnt.Workers noted in the days following that J2 was making a different noise, they described it as a whistle that changes from time to time, but not the typical servo sound. They called a company for whom I contract my services as a tech and they ordered a new J2 servo, and then they asked me if I would install it. My first question was, did they over pressurize the reducer and blow a seal, and then went to their facility to investigate. I found,
1) The sound is more a crunching/sqeaking. It's easy to imagine seals material being chewed up in a planetary gear while listening.
2) The servo quickly gets too hot to touch.
3) The brake seems to disengage when the servos activate, but I can't comment on whether it is dragging or not.So main guess is that the seal(s) are popped off and caught up in the reducer gears and/or servo brake? No alternative explanations seem very likely to me.
I've received a quote for at the small bits (all in stock) and the reducer, which includes the seal, I believe, which is 4 weeks away! If the lead time is so long, I'm thinking, then this might not be a common problem, and maybe I don't need to be replacing it. And anyway, it's so expensive it might as well be gold. So, anyway, when the servo comes I'm going to put it in anyway, and then I can get a look inside.
Which brings me to practical problem #2, the balancer. The Fanuc tech I talked to described the J2 refit as "a very big job". Hopefully if you have read this far, then you know what he is talking about. Essentially, you cannot rest the arm on the floor to remove the servo, as the balancer tension will make it lift. The balancer needs to be disconnected at the (bottom?) clevis and the arm supported at the balancer's neutral point. Can anyone please comment on this procedure, specifically, finding the neutral extension before disconnecting. I want to be confident going in as failure has obvious consequences. Also if you know about any complications in the whole task that I'm not aware of, I would be very appreciative of your advice.
Complications:
- This palletizing robot is elevated 10'
- There is no overhead crane, only a forklift which I have not seenI may take down the safety fence and put up scaffolding. I have also considered having an adjustable post fabricated to bolt to the floor, or using chains hung from the ceiling beams and connected to the lift points of link 2 or 3. Whew, sorry about rambling on, I want ed to be as precise as possible. Thank you for your time and thoughts.

Thanks to everyone who has responded to my other posts. I am going to service a VR-016, but I don't have access to the maintenance manual, and Panasonic wants to sell a course to release the info. It's a used robot and the customer won't spend more. If anyone has a maintenance manual, I just need to know lube types and quantity, and input/output locations. Any help would be greatly appreciated. Thanks all.

Could anyone please give me the name of a viewer/editor for Panasonic .prg files. I've tried Notepad++ and MS Visual Studio. Thank you, Brad.

Okay, I just found replies to this topic here, if there is an alternative to G2 PC Tools I would still like to know about it. Thanks

Im ok. The welder needs to boot up before the controller. I could still use manuals thoufh if anyone could help me out. Thanks all.

I need manuals for a used YA series controller, VR016 robot, G2 pendant. I would be very much obliged if someone could send any of them to me. Thank you greatly in advance. The welding unit activates the gas solenoid, but I can't activate it, or feed wire from the pendant.
