178 EtherNet/IP – Communication profiles
References
References are 16-bit words containing a sign bit and a 15-bit
integer. A negative reference (indicating reversed direction of
rotation) is formed by calculating the two’s complement from the
corresponding positive reference.
ABB drives can receive control information from multiple sources
including analog and digital inputs, the drive control panel and a
fieldbus adapter module (for example, FENA). To have the drive
controlled through the fieldbus, you must select the module as the
source for control information, for example, reference.
Scaling
References are scaled as shown below.
Note:
The values of REF1 MAX and REF2 MAX are set with drive
parameters. See the drive manuals for further information.
In ACSM1, ACS850, ACQ810, ACS880 and ACS580, the speed
reference (REFx) in decimal (0…20000) corresponds to 0…100%
of the speed scaling value (as defined with a drive parameter).
In ACS355, drive parameter REFx MIN may limit the actual
minimum reference.
