Control through the embedded fieldbus interface: DCU 16-
bit profile
Control and Status words for the DCU 16-bit profile
When the DCU 16-bit profile is in use, the embedded fieldbus interface writes the
fieldbus Control Word as is to the drive Control Word bits 0 to15 (parameter
EFB MAIN CW). Bits 16 to 32 of the drive Control Word are not in use.
Status Word for the DCU 16-bit profile
When the DCU 16-bit profile is in use, the embedded fieldbus interface writes the
drive Status Word bits 0 to 15 (parameter
EFB MAIN SW) to the fieldbus Status
Word as is. Bits 16 to 32 of the drive Status Word are not in use.
References for the DCU 16-bit profile
The ABB Drives profiles support the use of two fieldbus references, REF1 and REF2.
The references are 16-bit words each containing a sign bit and a 15-bit integer. A
negative reference is formed by calculating the two’s complement from the
corresponding positive reference.
The fieldbus references are scaled before they are written into signals
EFB MAIN REF2 for the use in the drive. Parameters
FBA REF1 MODESEL and
FBA REF2 MODESEL define the scaling and
possible use of the fieldbus reference REF1 and REF2 as follows:
• If you select value
Speed
, the fieldbus reference can be used as a speed
reference and it is scaled as follows:
• If you select value
Torque
, the fieldbus reference can be used as a torque
reference and it is scaled as follows:
