12 System data
The various control functions and methods according to the selected
Configuration
30 are
supplemented by control and special functions. For monitoring the application, process parameters
are calculated from electrical control parameters.
12.1 Actual value system
Parameter
Factor Actual Value System
389 can be used if the drive is monitored via actual value
Actual Value System
242 .
The
Actual Frequency
241 to be monitored is multiplied by the
Factor Actual Value System
389
and can be read out via Parameter
Actual Value System
242 , i. e.
Actual Frequency
241 x

12.2 Volume Flow and Pressure
Parameterization of factors
Nominal Volumetric Flow
397 and
Nominal Pressure
398 is necessary
if the matching actual values
Volumetric Flow
285 and
Pressure
286 are used for drive monitoring.
The conversion is done using the electrical control parameters.
Volumetric Flow
285 and
Pressure
286 are referred
to Active Current
214 in the case of sensor-
less control methods. In the case of the field-oriented control methods, they are referred to the
torque-forming current component
Isq
216 .

Point A in the figure describes the rating point of a pump. The transition to partial load operation
mode B1 can be effected at a constant pressure H (change of conveying flow Q, pressure H remains
constant). The transition to partial load operation mode B2 can be effected according to the bad
point method (change of pressure H and conveying flow Q). Both methods can be realized with the
integrated technology controller in configurations 111,211, 411 and 611. The actual values displayed
are calculated according to the bad point method independently of the selected
Operation Mode
440 of the technology controller.
