HITACHI SEIKI ABIKO VA 55 NO. 55158 WITH FANUC SYSTEM 11

[M.RISHIKESH]

Good Morning to all of u,

Sirs, please find below details of problem in following machine :

Machine details are as Under
HITACHI SEIKI ABIKO
FABRICATION 1987
VA 55 NO. 55158 WITH FANUC SYSTEM 11, TYPE A20B-0076-B501, NUMBER 1610 1985-11

Subject machine was running quite alright till there was a power failure.
After that when machine was switched ON, it came into IPL mode.
Manually loaded all CNC parameters as per hardcopy backup of another Machine Model VA 45

We do not have PC parameter backup that means no details of Timers, Counter, Keep relays, Data etc

We are facing following problems

a) If Mode selector switch is kept at Jog, Reference Return, Handle mode, then Alarm Red LED on operator panel gets ON & as per diagnostics, this is because one bit under D148 is ON & when we refer to details of that bit of D148 in a manual of that machine, it indicates towards problem with Mode Selector switch but under Input Diagnostics X, we are finding that bits are changing correctly for different modes and also CNC is correctly switching over to Handle, Jog, Reference etc as per selector switch position of Mode Selector switch

b) If Mode Selector switch is kept at MDI, memory, Edit etc then no problem that means Alarm Red LED is not getting ON & also CNC is changing correctly to MDI, Memory, Edit as per the switch position of Mode Select switch

c) We were not able to move axis in Jog then we changed Parameter 1400.7 to 1 then Jog is alright

d) We are not able to reference the axis manually but we are able to reference all the axes with G28 command

We loaded 5600 series parameters for Spindle also just by referring to Fanuc Manual as there was no backup of this 5600 series

e) Spindle gear was not in engaged position so by pressing the solenoid valve, we could engage the gear & as per ladder, spindle is in hi gear, Lubrication pressure switch feedback & also feedback of tool clamp & High gear found to be alright & in this condition When we command say M03 S200 or any rpm, like M03 S1200 then spindle starts slowly and stops after say half rotation with Feedhold and Alarm LED & as per diagnostic D, it is due to spindle start check alarm

When spindle starts to rotate we find in Ladder that R 1322 (spindle start) gets ON and stops because R 622 gets OFF

f) we could not search R 622 in ladder
In Ladder page, we find soft keys for Search (W) and Search (M), but say if we type R1322 and press Search (W), we are not able to go to R1322 so manually we need to do page down till we reach R1322
Can u pl tell what is the correct way of searching any coil in Fanuc 11M controllers
Kindly go through all the points and in case u or any of ur friends have got the complete NC and PC parameters backup, kindly send it to us as it is a very important machine

Please email at maddala.rishikesh@tatamotors.com

Thanks a lot

Best regards,

Have you gotten any help yet on this issue? If you have not, I believe I have the original software for this machine as well as the YuYu software required to load it all. The alarms you are getting are due to the addresses not being correct. The parameters you loaded from another machine have to be within about a 15 number serial range, i.e. 55150 - 55165. As far as the PC parameters go their are a lot of data addresses that are assigned through these that tell the system how to communicate from the PC and NC communications card. This problem is not uncommon although losing the parameters tells me that the batteries are in need of replacement. If you are still in need of the software to get your machine up and running get ahold of me via my email address as follows: jkelsay1@cox.net

Good day,
