I want to know if somebody can help me.
I have a problem with a Machining Center Tsugami FMA3, this machine have a controller Fanuc 16M.
I can do Tool Change in MDI mode, but when I work in memory mode I can't do it, and this error message then appears:

T33 comand only for MDI

What's wrong?

First thing to do is to check your parameter settings for completeness.

Post a sample program for us to look at. I does seem to be a parameter setting because that shouldn't happen during memmory mode. T33? How many tool pockets does your machine have? Most machines are 30 tools unless it's a Horizontal.

First, Thank's

The machine is a Machining Center with 4 axis and 64 tools, but now doesn't work a servo(1 tool magazine), then only works with 32 tools.
I'v tried do tool change using the codes below.

Look for circuit continuity.

IF the feedback system on the servo is screwed up (broken wire, bad encoder, etc), the machine will/will not move even though it thinks it did.

WHen problems like this occur, you need to systematically go thru the whole process. It could be one thing or a the daisychain effect of several that, by themself, wouldn't matter. But in unison, problems.

This is a different type of problem then someone normally sees. 1st thing I would look into is to be sure that the tool change command (M6) is not actually a macro or sub program with an M6 alias. Look if any of the parameters #6071 - #6089 are set to "6". If one of them are, then there is a program o90?? that could be messed up and giving you the problems.

M Code SubProg
o9001 6071
o9002 6072
o9003 6073
o9004 6074
o9005 6075
o9006 6076
o9007 6077
o9008 6078
o9009 6079
M Code Macro
o9020 6080
o9021 6081
o9022 6082
o9023 6083
o9024 6084
o9025 6085
o9026 6086
o9027 6087
o9028 6088
o9029 6089
Good Luck

A t33 command alarm, you most likely have tool all ready called. Make sure pocket #6 is empty, it may have to be returned to its original positon.
