I've got a programming problem with an Okuma & Howa ACT 3 lathe with Fanuc 15-T control... thanks to DCoupar I got the rough canned cycle syntax which is the following
G71 P100 Q200 U0.025 W0.010 D0.050 F0.008 S700
and when I run my program it gives me an Improper G Code alarm when it gets to this line... Does anyone know why its giving me this error
Gandp, I've made the changes you suggested but it's still giving me the Improper G Code Alarm.... This lathe has recently been purchased by the company I work for and I'm wondering if there is such a situation where this lathe doesn't support canned cycles....Any ideas?
Improper G-code typically means that the machine does not support the canned cycles that you are programming. IOW the canned cycle option is not activated in the control.
I've tried the "2 line" command and I'm still getting the same error.... I'm thinking that i don't have the canned cycle option enabled on this machine... how do I enable this feature?
try this method.

Stevo's comment regarding the control not supporting the canned cycles being programmed is correct and the most likely cause of this alarm condition.
Thanks guys for your input... i've tried all the methods suggested and the machine still gives me an Improper G Code alarm. As Bill has suggested, I really do think that this machine does not have canned cycles enabled and so I guess I'm stuck at programming line by line.
G90 and G94 might be available which will simplify programming a little bit.
