problem in thread milling on fanuc 10M controller.

[kumar_manikonda]

I have a Mori seiki-mv junior with fanuc 10m controller. I would like to do thread milling on it. I got a message of PS-186.illegal plane command. According to some thread i found out in CNC zone, I tried to change the parameter 9100 bit 2 to 0. I got a message the parameter is locked. Please help ASAP.

I have an MV-Jr as well, to my knowledge it won't do helical interpolation. Without this you can't program a helix. You can break the helix into small lines if your CAM software will do this, the file size will just be pretty big.

I don't have enough memory in my control, so I have to drip feed when threadmilling. Due to that I had to get a unit from Shop Floor Automation that allows me to use an SD chip to drip feed from.

Rgds,

I didnt verify parameter, but assume its right...those parameters have to be entered in hex.
hold minus and period at boot, IPL screen promps you to enter 1~6, instead hit 99 [input], prompt will ask number of axes, then OP1?

OP1 is the hexadecimal equivalent value desired for 9100 in binary

pretty sure this is in the later maintenance manuals under 'replacing master PCB' or something like that...

BTW, to convert 8 bit binary to hex is super easy, split it in half and add the bits as

8-4-2-1 8-4-2-1

ex: say you want to put 01011010 into a parameter as hex

split in half
0101 1010
8421 8421
*4*1 8*2*
=5 =10
=5A (hex)

0001=1
0010=2
0011=3
0100=4
0101=5
0110=6
0111=7
1000=8
1001=9
1010=A (10)
1011=B (11)
1100=C (12)
1101=D (13)
1110=E (14)
1111=F (15)

just have to be certain to have full backups as some changes will reconfigure memory. accidentally changing some bit that requires support could lock up/require all clearing- so Ive heard
