Controls frequency/speed reference settings of a drive.
ESP reference

Fixed speed ref /
unit32
Defines the source for the speed reference. This should
be used with external control location 1 (EXT1).
The unit (Hz or rpm) of the speed input is determined
with parameter
19.20 Scalar control reference unit

Note: If the input reference has a custom scaling, then
it should be explicitly set with parameter

8
Speed reference comes from the setting in control
panel.
Panel reference
9
Speed reference is taken from Embedded fieldbus
reference 1 or from the ACS880 control panel.
EFB or panel
Note: The reference from the control panel can be used
only when EFB ref 1 is zero or EFB communication is
lost (see parameter
58.7 Communication diagnostics
,
bit 10).
The EFB or panel selection also allows to start and stop
the drive from embedded fieldbus using EFB control
word, bit 3.
10
Speed reference is taken from Fieldbus adapter A
reference 1 or from the ACS880 control panel.
FBA or panel
Note: The reference from the control panel can be used
only when
is zero or FBA
communication is lost (see parameter
).
The selection FBA or panel also allows to start and stop
the drive from the fieldbus using Fieldbus control word,
bit 3.

Other [bit]
0.00 Hz / real32
Defines custom speed reference value.
This can be used as pump speed reference source if
parameter
is set to Fixed
speed ref.
Fixed speed ref
