No.
0 / real32Defines custom scaling for the parameter 75.11 Pump
speed ref source.
The resulting speed reference is then calculated as
follows:
Used pump speed reference = (75.19 Maximum
production speed *(75.11 Pump speed ref source/75.13
Speed reference scaler).
Note: If the pump speed reference input is used
directly, then set this parameter value to 0.

upon receiving start command.

NULL / unit32Defines the source for the speed reference. This should
be used with external control location 2 (EXT2).

Fixed speed ref
8Speed reference is taken from Embedded fieldbus
reference 1.
Panel reference
9Speed reference is taken from Embedded fieldbus
reference 1 or from the ACS880 control 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.
EFB or panel
10Speed reference is taken from Fieldbus adapter A
reference 1 or from the ACS880 control panel.
Note: The reference from the control panel can be used
only when 3.5 FB A reference 1 is zero or FBA
communication is lost (see parameter 51.31 D2FBA A
comm status).
The selection FBA or panel also allows to start and stop
the drive from the fieldbus using Fieldbus control word,
bit 3.
