Fanuc Series oi TD Tool Comp

[cgabel60]

We have a retrofit Tuda lathe with a Fanuc oi TD control. I cannot get it to read the T0101 line, just locks up. I can change it to T1 and passes on with the program. Obviously not picking up any offset. I need this to read the T0101 command and pickup information for tool radius compensation. Purchased used so we have very little information on the machine. My guess, it's a parameter. Anyone else experience this?

Below is a test program:

G20 G40 G80 G90 G99
G50 S120
N31 T0303
N32 G96 S250 M03
N33 G00 G42 X2.21 Z0.1
N34 G01 X2.65 Z-0.12 F0.007
N35 Z-0.825 F0.01
N36 X3.25 Z-1.125
N37 Z-1.85
N38 G02 X4.05 Z-2.25 R0.4
N39 G01 X4.51
N40 X4.8 Z-2.395
N41 U0.2
N42 G00 G40 X8.0 Z5.0
N43 M30

Thanks

Its quite unusual for a relatively late model machine to react that way, but common for early Fanuc Control machines when calling the Tool and its Offset with the Spindle not running. Try the following command for calling the Tool up:

G00 T0303
If that works, the behavior of the machine can be changed via parameter setting.

Regardfs,

G50 specifies max RPM, in CSS mode.
S120 may be a typo.

Thank you, Bill, and Sinha. This gives me a few things to investigate.

Reviewing the parameter and changing my line of code resolved the issue. THANK YOU!

You should make the changes one at a time so as to determine the real cause.
