Set 914.7 to 0Dear 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 ??????????
