ABB drives profile technical data
Overview
ABB drives profile
The ABB Drives profile provides a standard profile that can be used on multiple
protocols, available on the FBA modules. This section describes the ABB Drives
profile implemented for FBA modules.
• ABB DRV LIM – The primary (and default) profile is the ABB DRV LIM profile,
which standardizes the control interface with ACH580 and ACH550 drive
products. This profile is based on the PROFIBUS interface, and is discussed in
detail in the following sections.
• ABB DRV FULL – This profile standardizes the control interface with the ACH580
and ACH550 drive products. This profile is also based on the PROFIBUS
interface, and supports two control word bits not supported by the ABB DRV LIM
profile.
Control Word
As described earlier in Control interface 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.
