Abstract (en)
[origin: WO2016071277A1] A method for operating a speed-controlled fluid pump (102) comprises the following steps: - providing an electric control current for the fluid pump (102), - providing a maximum value (201) for the control current, said maximum value corresponding to a maximum permissible pressure on the output side of the fluid pump (102), providing a threshold value (202) for the control current, said threshold value corresponding to an additional maximum permissible pressure on the output side of the fluid pump (102) and being defined depending on at least one boundary condition, the threshold value (202) being lower than the maximum value (201), - controlling the fluid pump (102) with not more than the threshold value (202) of the control current when the boundary condition applies in order to limit the pressure on the output side of the fluid pump (102) to a value provided for the boundary condition.
