Axes of NCUb to NCUd
The NCUs that are not master NCUs have the same axes with the exception of the axes for
the drive for drums TRV and TRH. The letter designating the position must be replaced
accordingly for the NCU and axis name (a, A → b, B to d, D).
Configuration rules
The following rules were applied for the configuration described below:
● Main spindle, counterspindles and axes that are assigned to different NCUs through drum
rotation while they are operating as illustrated in the above diagram "Main spindle ..."
must be configured in an axis container.
(HS
i
, GS
i
, ZG
i
, STN
i
).
● All main spindles for drum A are in the same container (No. 1).
● All bar feed axes for drum A are in the same container (No. 2).
● All counterspindles for drum B are in the same container (No. 3).
● All transfer axes for drum B are in the same container (No. 4).
● Main spindles HS
i
and their counterspindle GS
i
as well as the transfer axes for
counterspindle ZG
i
and the bar feed axes STN
i
of the main spindle are assigned as
follows for uniform load distribution purposes:
NCUa HS1-STN1,
NCUb HS2-STN2, ... etc.
● Slide axes Xij, Zij are solely local axes with a fixed NCU assignment.
● Slides are assigned to a dedicated channel of an NCU.
Slides can therefore be moved autonomously.
