ABB ACS880-104

Parameters 451
Head estimation Function output is the total dynamic head estimate calculated
from the user given input interpreted as the flow
measurement.
85.90 Q for the next H-
point
Displays the Flow value for the next missing Head point in the
custom user curve.
This signal serves for input assistance.
0.00
0.00...30000.00 Q for the next H-point. 10 = 1
85.91 Flowrate actual Displays actual flow rate calculated from the user defined
pump curve.
Note: In case parameter 85.71 Function type is set to Head
estimation, this signal displays the value used as the input for
the curve.
0.00
0.00...30000.00 Flowrate actual. 10 = 1
85.92 Head actual Displays actual head calculated from the user defined pump
curve.
Note:, In case parameter 85.71 Function type is set to
Flowrate estimation, this signal displays the value used as the
input for the curve.
0.00
0.00...30000.00 Head actual. 10 = 1
85.99 Pump curves status
word
Defines the pump curves status word. 0b0000
90
90 Feedback selection
Motor and load feedback configuration.
See also sections Encoder support (page 86) and Position
counter (page 88), and the diagram on page 647.
90.01 Motor speed for
control
Displays the estimated or measured motor speed that is used
for motor control, ie. final motor speed feedback selected by
parameter 90.41 Motor feedback selection and filtered by
90.42 Motor speed filter time.
In case measured feedback is selected, it is also scaled by
the motor gear function (90.43 Motor gear numerator and
90.44 Motor gear denominator).
This parameter is read-only.

-32768.00 …
32767.00 rpm
Motor speed used for control. See par.
46.01
90.02 Motor position Displays the motor position (within one revolution) received
from the source selected by parameter 90.41 Motor feedback
selection.
In case measured feedback is selected, it is also scaled by
the motor gear function (90.43 Motor gear numerator and
90.44 Motor gear denominator).
This parameter is read-only.
