AXOR Minispeed 60 analog servo driver failed. Troubleshooting help needed.

[Ian.M]

Hi guys,

I've got an AXOR Minispeed 60 servo drive, used in what's basically a robot arm, that's failed.  It immediately indicates axis tripped in the control software (which is propitiatory and highly application specific).

The fault has been localised by substitution to the Minispeed 60, and we believe to its small signal daughter-board.  There was no damage visible on a close visual inspection of the daughter board.

I've just assembled an extender card so we can make measurements under power in situ, and have a spare DIN41612 connector so may be able to make up a bench test harness for it.

Any assistance from anyone familiar with the Minispeed drives would be appreciated.   A service manual or schematic would be particularly useful.

Unfortunately I am only on site one day a week so any measurements requested will take a while.
