Problem in commissioning

Hi sirs,

on a commissioning of a 1FE1114-6WT11-1BA0 with 840dsl i notice i'm not able to enable all the axis objects.

Here the photo of the state of NCU and drives: [snip]

i've never had this problem and i don't know how to solve, since i'm started from a PLC of another application.

How can i do?

I solved because i noticed that in the first cell of drive parameters there was an error 42, for which the result between p844 and p845 was wrong.

I went to take a look over them and i typed "1-BICO" in p845. Before it was "BICO 1:722.1".

All the axis became in green and i succeeded to move the spindle.

But even after reading the definition of BICO, i cannot understand what i did and why i hade to modify that parameters. If someone can help me...
