Mitsubishi Kolibri 500 MBE ATC problem

Hello everyone,
I am new to Mitsubishi Kolibri 500 MBE CNC machine. I am seek to perform automatic tool changer (ATC) in the Mitsubishi Kolibri 500 MBE.

There are no tools loaded into the magazine of Kolibri currently. The applied Tool Change Macro is shown below. I have tried to load the tool with T1 M06 in MDI mode. But the program at first detect #1032 = 1 and skip to the line N100. I have look into the handbook, #1032 is a system variable with related to Register. Anyone have an idea what could be the reason that #1032 is always 1 and possible way to solve this issues?

In the case that, I comment and hide the line " IF[#1032EQ1]GOTO100 ", the Tool Change Macro is only able to run until M11 (where the ATC elevator move down as ** below) and got sucked and doesn't run further. Anyone have similar issue as this and know the possible solution?

The given Tool Change Macro from the machine tool builder are as following;

Thank you and I look forward for your discussion

#1032 is possibly being used by the machine builder to keep track of the ready state of the toolchanger. The definition of #1032 is determined by the machine builder's ladder program, not Mitsubishi. To determine why #1032=1, you will need to look at the ladder diagram and see what condition turns on address R72 bit 0. If you find that in the ladder, post a screen image of the rung in Monitor mode so we can see the active and inactive state of the logic.

Post a picture of the machine and toolchanger. In translation, ATC-elevator is ambiguous. Often when an ATC step freezes, it is caused by a switch or sensor failing to indicate completion of the step.

Thank you for your reply, Vancbiker.

I have check the parameter #1032 is related to Register R6436, R6437. Then, I have search the Registers in Ladder diagram of the the machine with some related information form the user manual (LD R6473, R6473, ATC instruction, PLC sequences) as the following link Kolibri ATC – Google Диск.

The photo of the machine and the place where program stucked is also this the same link (Kolibri, M11 elavotor stucked). To give better explanation of the issues where the Tool Change Macro during the execuation of ATC, it will always stop at the line M11 (as marked in the first post). This is a place where the ATC elevator opened (where a cover opened for the tools to undergoes tool exchange).

Once again I am eager for your reply. Thank you.

Rungs 290 and 315 of the ladder image you linked are pretty basic comparison checks that set R6436 to 0 or 1 depending on the results of comparison. You will need to figure out what data R8400 and R10620 are representing. For #1032 to be set to 0, R8400 and R10620 must not be equal.

As a small progress update, I have require the description from R8400 and R10620 from mitsubishi as I can't find it on the user manual. However, I realized that sometime the #1032 parameter is 0, where R8400 and R10620 are not equal.

I will update here again if there are something new and useful.

Once again thank you!
