74.80 Observer speed
measured
Displays the speed measured by the Backspin Speed
Observer function.
0.00
0.00...600.00 Hz Observer speed measured. 1 = 1Hz
74.99 ESP start/stop sw Displays status word of the functions controlling ESP specific
start/stop logic.
75
75 ESP reference setup
Controls frequency/speed reference settings of a drive.
See section Underload and overload protection (page 52).
75.11 Pump speed ref
source
Defines the source for the speed reference.
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 75.13 Speed reference
scaler.
