We have sometimes a problem with Z-movements on our DMU125. It's erro Z07, which has something to do with the Z-axis motorencoder.
So today I replaced the encoder in a Siemens 1FT06 motor.
I restarted the control but it shut itself down with an error E07 and I could do nothing.
So I placed back the old encoder, but after restarting it shut down again with error Z68, which means no motor current.
Did I destroy de Z-axis drive?
What should I do to check this?
