Dear Sir

Good Morning to u all.

In one of our HMCs, we were getting Battery Fault and also BAT was blinking on Screen

a) We checked and found battery voltage to be alright
b) Still we replaced Battery (1.5V X3 nos.) with new Set
c) Taken out Memory PCB, checked, battery Voltage on PCB found alright (as u r aware, white connector from Battery is connected to this Memory A4 PCB)
d) Taken complete backup and erased memory with Reset and Delete---- still BAT was blinking
e) Memory PCB A16B-2201-010 replaced with similar PCB but we retained all EPROMs of Memory PCB of this Machine
f) After Power ON, we did not get Battery Alarm and BAT was not blinking but we started getting error 998 ROM Parity OB1 that means EPROM located at OB1 slot was defective so OB1 (9046 001I replaced with 9040 001I as were not having 9046 001I)
g) Now we are not getting error 998 but we are getting errors 446 : 4 axis Disconnect and Error 447 4 axis Digital Parameter

This machine has 4th axis, which we are not using since last 2 years due to mechanical problems and around same time done necessary bypass in parameters to run the basic machine with 3 axes till recently and EPROM at OB1 9040 001I taken from another Fanuc 0M machine which has no 4th axis

Please advice on how to bypass Error 446 and 447 ??????????

Set 914.7 to 0

Greenery_fr

Thanks for ur reply

Presently 907 11011100

913 10010010 and 914 11000000

Then changed 907 to 11010100 and 914 to 0000000

Now we are not getting any error after control ON and also B is not appearing on screen under Machine Position screen

But if we move X,Y,Z or W (Magazine axis), we are getting SPC alarm for pulse coder disconnect for x,y,z and W error 339, 329, 359 etc

Kindly advice why it is so ????????

Hi

Hope it will help you

[M.RISHIKESH]

Hi Mr. Greenery

Can u please give me ur email id?

After I changed bit 907.3 and 914.7 to 0, no error related to B as B got completely bypassed but whichever axes (x,y,z w) is moved we get SPC error 3n9 for that particular axis

As u know all SPC of all axes can not go bad at a time and there must be some common problem?

We tried by replacing Axis control PCB where all the connectors from SPC of all axes get conected? with another ok machine, still same problem

Reloaded all machine parameters.

what else could be the reason sir for error 3n9 for all axes ???

Kindly advice

Hi M. Rishikesh

Are your motor alpha series. If your motors were alpha series. The servo software 9040 do not support alpha series

Hi Mr. Greenrey

Thanks once again for such prompt response. As we have alpha drives and motors, 9040 might be causing error 3n9 for all axes, we will try to burn a blnk EPROM with another OK machine to see further.

Please confirm if EPROMs in the order of FE1J, FC1J, FA1J, F81J, 201J are for memory in higher order ???????? and OE1 and OE2 are for PMC

Hi M.Rishikesh

The OE1 and OE2 for PMC, can you take a picture of your Mem card with all chip pluged in ?

Hi

Hope it will help you

dear Mr GF,
I have a machine which use fanuc Om system, but today this machine lost parameter list so i have to set up one again, but after i restart, it show 447 4 asix digital parameter alarm, but this machine have only 3 asix. I dont know what to do, pls help me!

[fordav11]

a possible answer is in posts #2 and #3

[Willydke]

I have a 9046 001I this eprom is the spindel sofware,

[lancy159]

how to setup fanucOM encoder to 0？

[gbowne1]

Slightly OT, but how does one change a 0M Model C to a 0MF??

[Willydke]

wath means for you setup OM encoder to O. wats is your alarm specified?

[Willydke]

upgrade the sofware locaded in men board

[lancy159]

Who can give me fanuc Om parameter list ? Please, i really need it
