Abstract
A method adjusts values of a plurality of parameters of at least one controller of an electric drive system. The method provides an individual replacement parameter value that can be adjusted by a user. After adjusting the replacement parameter value, the method calculates the values of the plurality of parameters from the adjusted replacement parameter value.
Claims3
A method for setting values of a plurality of parameters of at least one controller of an electric drive system, the method comprising:
- generating an operating surface on a display;
- setting values of a plurality of parameters through the user interacting with the operating surface, wherein setting the values of the plurality of parameters comprises:
- when the operating surface is in a first setting mode:
- receiving a value of an individual replacement parameter by the user interacting with the operating surface in the first setting mode, wherein the user sets only the individual replacement parameter value;
- and
- when the operating surface is in a second setting mode that is distinct from the first setting mode:
- receiving input data related to at least one control circuit to which the at least one controller is assigned by the user interacting with the operating surface in the second setting mode;
- when the operating surface is in the first setting mode, calculating values of the plurality of parameters from the set individual replacement parameter value;
- and
- when the operating surface is in the second setting mode, calculating values of the plurality of parameters from the input data from the user relating to the at least one control circuit;
- wherein:
- the electric drive system has a position controller and a rate of rotation controller;
- the plurality of parameters are parameters of the position controller and parameters of the rate of rotation controller;
- the position controller has a position controller P parameter that is set by way of the operating surface when setting the values of the plurality of parameters;
- and
- the rate of rotation controller has a rotation controller P parameter, an I parameter, and a filter time that are set by way of the operating surface when setting the values of the plurality of parameters.

An electric drive system, comprising:
- at least one controller;
- a display;
- and
- a controller parameterization device that is configured to execute program code to:
- generate an operating surface on the display;
- set values of a plurality of parameters through a user interacting with the operating surface on the display, wherein to set the values of the plurality of parameters, the controller is configured to:
- when the operating surface is in a first setting mode:
- receive a value of an individual replacement parameter by the user interacting with the operating surface in the first setting mode, wherein the user sets only the individual replacement parameter value;
- and
- when the operating surface is in a second setting mode that is distinct from the first setting mode:
- receive input data related to at least one control circuit to which the at least one controller is assigned by the user interacting with the operating surface in the second setting mode;
- when the operating surface is in the first setting mode, calculate values of the plurality of parameters from the set individual replacement parameter value;
- and
- when the operating surface is in the second setting mode, calculate values of the plurality of parameters from the input data from the user relating to the at least one control circuit;
- wherein the electric drive system further comprises a position controller and a rate of rotation controller;
- wherein the plurality of parameters are parameters of the position controller and parameters of the rate of rotation controller;
- wherein the position controller has a position controller P parameter that is set by way of the operating surface on the display when setting the values of the plurality of parameters;
- and
- wherein the rate of rotation controller has a rotation controller P parameter, an I parameter, and a filter time that are set by way of the operating surface on the display when setting the values of the plurality of parameters.
