ABB Drives profile technical data
Overview
The ABB Drives profile provides a standard profile that can be used on multiple
protocols, including protocols available on the FBA module. This section describes
the ABB Drives profile implemented for FBA modules.
Control Word
As described earlier in section Control interface on page 252, the
CONTROL WORD is
the principal means for controlling the drive from a fieldbus system.
The following table and the state diagram later in this sub-section describe the
CONTROL WORD content for the ABB Drives profile.
