Try Keep Relay 8 bit 5 (4th Axis is used). Set to 1 .
Hope this helps
Hello all, I am having some problems with my 4th axis installation. The rotary does not move!. I have checked the cables and there are no alarms on the controller. All 4th parameters from Doosan and table manufacturer are set. The clamping relay works and responds to M10/M11. I have sent parameter files to Fanuc, and they found no issues, all necessary cards are installed all options regarding 4th axis are open. The machine was prewired for 4th axis. Fanuc say I need to look in the PMC parameters to see if anything is wrong or missing. Any ideas what I should be looking for?
Thanks for any advise!
Best regards
John

In the ladder you have several conditions that need to be satisfied. G8.0 and G130.3 both must be on.These are coils in the ladder or parameter 3003. 0 & 2 to bypass these G bits. When you try to jog coil G100.3 for plus direction and coil G102.3 for the minus direction must be on when jogging. You can also check the SYSTEM Diagnosis page and while trying to jog see if any bits are set. They should all be zeros.
Hello Dale, thanks for your response! This parameter (Keep Relay 8 bit 5) is already OK! As are the other 4th axis PMC parameters in the blue Doosan book.
Hello drdos, thanks for your response! I'll have a look at it and see if that is the cure.
Hi motordude
Try this lot .Maybe 1 has been missed out somewhere. Ignore the FSSB settings if you have already done that. Ignore 5th Axis parameters also.
Hope this helps

Thanks a lot, Dale! I will try this out now. About your point 76 (carry out page 4 of axis parameters in blue book 13610/11695), I don't have this page! Only got 1,2 & 3. Any chance you may scan it and PM it to me? Many thanks for your help, very much appreciated.
EDIT: I don`t understand this: 7. Para 14343 = 4th = 3, 5th = 4

Hi John
14343 is to do with FSSB setting which you should have already done . If so ignore this step.If not then FSSB setup motor ID is the first thing to do.
Parameters 13610/11695 are to do with AICC and Machining condition select . Don't worry about these at the minute . See if the other parameters get the Axis Jogging.
If it works I will get page 4 over to you .
Hope this helps

Hi John
What motor is in the 4th Axis ?
drdos, I have looked into this. G8.0 is on G130.3 is not (B.IT4). Do I turn G130.3 on in parameter 3003, and should 0 & 2 be set to 1 or 0? When I try to jog, coil G100.3 & G102.3 does not respond for the 4th axis. XYZ responds. How do I turn these on? Checking the system diagnosis while jogging shows all zeroes.
Any advice would be much appreciated!
Best regards
John
drdos, here are some pics, but I am in my depths here, I have no experience with this. Is this what you are after? If not, could you please post a pic similar to what you are after. Thanks for your patience!
Best regards
John
EDIT: I made a mistake:
Setting parameter 3003.0 (ITL)=0 should give G0008.0 a 0. My machine gives a 1.
Setting parameter 3003.2 (ITX)=0 should give signal G0130.n on all axes (B.ITX, B.ITY, B.ITZ & B.IT4.) There is no B.IT4 signal on my machine

You did great!. First, the parameter 3003 bit 0 = 1 states that the G8.0 coil isn't being looked at. 3003 bit 2 = 1 states that the G130's coils are not being looked at. However in your case the G8.0 coil "contact" is being used for a condition for the 4th axis jog command. So bypassing G8.0 with parameter 3003 won't help your problem. Looks like keep Relay K0.5 says that the other axes MUST be in an interlock state before allowing the 4th axis to jog. G8.0 must be off, but without parameter 3003 bit 0 set to a 1 you will never jog anyways. You can try turning off the Keep Relay bit (K0.5) and see if you can jog the 4th axis. (May become an issue in Auto). If it does then I will need to see pic of the ladder G8.0 while commanding the 4th axis to move.
Thanks for the encouragement! I am not quite sure what you asked, so I set 3003 bit 0=0 and bit 2=0. Then I turned off the keep relay K0,5 (set to 0). I then got G0008 =1. I could not jog the axis. I am a little confused, in order to jog what should the 3003 0&2 be? Thanks for your help so far! I took at picture of the screen, when in MDI I get 1 in line 13, don't know if that is important. Turning the knob to job, line 13 is 0.
For testing only set 3003 0 & 2 to 1's Then see if G100.3 turns to a 1 when trying to jog the 4th axis plus direction. Keep K0.5 off for now. Is it possiable to send me the ladder from the machine? jim.lewis@cncusallc.com
All OK now! Jim Lewis of CNC USA, LLC - Home helped me solved this. Great guy!
Problem was twofold:
1. The service guy doing the install didn't put a jumper cable in CXA20 port, instead he put it in the DCC & DCP port. Luckily it seems there is no damage to the servo amp.
2. The cable going from the rotary to the CNC machine missed two wires in the W & X port.
