Need help on Fanuc OI-td series control

I just getting familiar with this control as it is a much newer model then what i am used to. I wrote a program to flex a piece of steel but when i try to tell it to use a the G71 canned cycle the machine doesn't understand and try's to take it all in one cut. does anyone know how to canned cycle an undercut on this control?

EG:

it starts at an OD of 11.25" and about 11.5" from the face of the piece. This is what i need it to canned cycle: i need it to plunge down at a 15 degree angle into a 20" radius to and OD of 7.5 and continue straight for 122" then into a 10" radius into a 15 degree angle back out to an OD of 9.5.

As far as my knowledge goes it should b able to be done with a G71. is there a parameter that i need to change or is there a different command for it?

thanks

you would need to activate G71 type 2 for profile undercut, by program both axis in the first line, e.g. (this is a mm program)
G0 X150 Z6
G71 U4.0 R1.0
G71 P2 Q3 U-2.4 W.1 F.32
N2 G0 X 100 Z4
.....
N3 X145 Z-40

Thank you very much funny thing is inhad time to sit down and go through all the manuals for the machine and figured it out. It just took me a bit tonfigure out such of the 6 manuals to look in and then decipher the overly technical language lol. Thanks any ways big help
