• If you select value Raw data, the fieldbus reference REF1 or REF2 is the drive
reference without scaling.
1)
Unit depends on the use of the reference in the drive. Rpm for speed reference and % for torque.
 Actual signals for the DCU 16-bit profile
Both the ABB Drives classic profile and ABB Drives enhanced profile support the use
of two fieldbus actual values, ACT1 and ACT2. The actual values are 16-bit words
each containing a sign bit and a 15-bit integer. A negative value is formed by
calculating the two’s complement from the corresponding positive value.
The drive signals are scaled before they are written into fieldbus actual values, ACT1
and ACT2. Parameters 50.04 FBA REF1 MODESEL and 50.05 FBA REF2
MODESEL both select the drive actual signals and define the scaling as follows:
• If you select value Speed, drive actual signal 01.01
SPEED ACT as scaled and
written to the fieldbus actual value. The table below shows the scaling:
• If you select value Torque , drive actual signal 01.06
TORQUE is scaled and
written to the fieldbus actual value. The table below shows the scaling:
