Hi All,

We bought a Hitachi Seiki VM40 III old machine with Yasnac J300M. We had many problems with the machine, but now only the tool change doesn't go through. (parameter lost, no parameter file, IC-s replaced on the I/O panel, servo drive replaced, limit switches replaced and other electronic repairs)

Now the machine after the M6 is looking for the tool and after it stops in the middle of the tool change, after 2 mins we get User alarms:
75006 M. S. T. B. code cycle time over
75175 ATC cycle time over

Please find the video here: https://youtube.com/shorts/huvKu_aVLEQ?feature=share

Can anybody help us?

Kind regards,
Andras
