fagor sincos resolver initialization

[sabiuta]

hello,

i have a fagor 8055 on a lathe with fkm drivers and sincos encoders.
i swhitched the encoders SRS50- HFA0-K01 between X and Z, and back and after this when i try to move axis is running very fast and stops with overspeed or overtorque alarm. how can i solve it?

It sounds like run away, this can be due to open connection on the feedback or resolver not connected properly.

is possible for one axis, but for both is quite strange for me . I cannot imagine what mistake I've done.

One thing that is common to both resolvers is the exitation power supply?
If you have a 'scope it may help a bit in diagnosing?
