422 Parameters
EFB1 ref 03.09 EFB reference 1 (see page 156). 5
EFB2 ref 03.10 EFB reference 2 (see page 156). 6
Fixed speed ref Speed reference is taken from parameter 75.12 Fixed speed
ref.
7
Panel reference Speed reference is taken from Embedded fieldbus reference
1.
8
EFB or panel Speed 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 58.07 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.
9
FBA or panel Speed 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 03.05 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.
10
Other [bit] Source selection (see Terms and abbreviations on page 148). -
75.12 Fixed speed ref Defines custom speed reference value.
This can be used as pump speed reference source if
parameter 75.11 Pump speed ref source is set to Fixed speed
ref.
0.00
-600.00...600.00 Hz Fixed speed reference in Hz. 10 = 1Hz
75.13 Speed reference
scaler
Defines 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.
0
0...30000 Speed reference scalar. 1 = 1
75.15 Starting speed Defines the speed at which drive begins modulating upon
receiving start command.
1.00
0.00...600.00 Hz Starting speed. 10 = 1Hz
75.18 Minimum
production speed
Defines minimum production speed reference in absolute
value.
0.00
0.00...600.00 Hz Minimum production speed. 10 = 1Hz
75.19 Maximum
production speed
Defines maximum production speed reference in absolute
value.
50.00
0.00...600.00 Hz Maximum production speed. 10 = 1Hz
75.21 Acceleration time Defines the time for the pump-motor to accelerate from 0 up
to the speed set in parameter 46.02 Frequency scaling.
Note: If parameter 75.23 Ramp switch speed is set to greater
than 0, then this parameter ramp time setting is used while
speed reference is in lower speed region.
