    Abstract: A frequency converter (100) comprises a processor (102), memory (104) and basic software (106) in the memory, the execution of which software implements the basic functionality of the frequency converter. For application-specific customization, the memory of the frequency converter is arranged to include application software (108) that contains callable functions (210) and is installable separately from the basic software. The frequency converter is arranged to execute the basic software (106) and the application software (108) with the same processor (102). The basic software (106) calls a function of the application software and/or provides functions of its own to be called by the application software indirectly via a link (240k) in a call table (240), the location of the link in the call table being independent of the location of the function (210) corresponding to the link in the memory.

    Abstract: An exemplary frequency converter and method are directed to estimating an operation point of a pump when the QH characteristic curve of the pump is known. The frequency converter controls the pump, and a process curve is estimated when a first operation point of the pump is in the nominal range. The process curve defines a head as a function of volumetric flow. A rotational speed of the pump is determined and a QH characteristic curve of the pump is converted to a current rotational speed of the pump based on affinity laws. A second operation point of the pump is estimated by determining an intersection point of the converted QH characteristic curve and the estimated process curve.
