Fanuc 0M-C Toolchange works in Auto but not MDI

Hi folks,

I have a 2000 Feeler FV800 with a Fanuc 0M-C control and umbrella carousel style toolchanger. It uses a macro B tool change program.

I can run a little program in Auto with a T0x M06, and it works just fine.

The problem is if I type T0x M06 into MDI, the macro starts reading, but stops with the cursor on the line "G91G30Z0M42 (TOOL CHANGE POSITION)" with no alarm or anything, just stops. Almost like an option stop, but when I hit cycle start again nothing happens.
I tried T0x M98 P9001; and it does the same thing.



I guess I can keep that little program and just edit it to whatever tool number when I want to do a manual change.. but that's kind of annoying, any ideas?

What is the content of Diagnostic 700 when it is hung up?

Nevermind! Just figured it out.. I found a PLC Data parameter D486.5 "mdi-b atc can work PLCSW". I changed that baby from a 0 to a 1 and we're off to the races! Thanks though.

Next issue, chip conveyor turns on every time I hit cycle start, dont like that either. But no mention of conveyor-anything in the plc data params.

Well that's a new one. Is this some kind of lockout to prevent the operator from tampering with the tools?

Thank you for the PLC Data parameter D486.5, I have a Feeler FV-600 with same problem, but not any more thanks to you. Where did you finde the information about D486.5? I have been struggling long time to solve this tool change from MDI. First thing I realized was the Parameter 903#4 need to be 1 for MDI EXEC B macro from MDI, but then I was stueked same place as you was.
Many thanks again, grate work.
