DCU 32-bit profile
Control and Status words for the DCU 32-bit profile
When the DCU 32-bit profile is in use, the embedded fieldbus interface writes the
fieldbus Control Word as is to the drive Control Word (parameter
EFB MAIN CW
).
Status word for the DCU 32-bit profile
When the DCU 32-bit profile is in use, the embedded fieldbus interface writes the
drive Status Word (parameter
EFB MAIN SW
) as is to the fieldbus Status Word.
References for the DCU 32-bit profile
The DCU 32-bit profile supports the use of two fieldbus references, REF1 and REF2.
The references are 32-bit values consisting of two 16-bit words. The MSW (Most
significant word) is the integer part and the LSW (Least significant word) the fractional
part of the value. A negative reference is formed by calculating the two’s complement
from the corresponding positive value of the integer part (MSW).
The fieldbus references are written as is into the drive reference values (
EFB
MAIN REF1
EFB MAIN REF2
FBA REF1 MODESEL
and
FBA REF2 MODESEL
define the reference types (speed or torque) as follows:
• If you select value
Raw data
, the fieldbus reference type or possible use is not
selected. The value is freely usable as a speed or torque reference in the drive.
• If you select value
Speed
, the fieldbus reference can be used as a speed
reference in the drive.
• If you select value
Torque
, the fieldbus reference can be used as a torque
reference in the drive.
The table below clarifies the relation between the fieldbus reference and drive
reference (no scaling).
1)
If the reference value is used as the speed reference, it will be the motor speed in rpm. If the reference
value is used as the torque reference, it will be the motor torque in percent of the motor nominal torque.
