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. The ABB Drives profile
reference can be found in objects 0×2006 (hex) (Transparent
Reference) and 0×4000 (hex), subindex 3 (Reference 2).
ABB drives can receive control information from multiple sources
including analogue and digital inputs, the drive control panel and a
communication module (e.g. REPL-01). In order to have the drive
controlled through the fieldbus, the module must be defined as the
source for control information, e.g. reference.
References are scaled as shown below.
Note: The values of REF1 MAX and REF2 MAX are set by drive
parameters. See the drive manuals for further information.
