A control arrangement for varying the speed of rotation of an electric motor 12, is provided with various potentiometers 11 for setting various operating parameters of the motor, for instance the acceleration time, the deceleration time and the start-up boost. The potentiometers 11 are connected to a display by way of which the respectively set operating parameter of each individual potentiometer 11 can be displayed. Advantageously only one display 14 is provided for all potentiometers 11 and each individual potentiometer 11 can be separately called up by way of a selector switch 15 and the correspondingly set operating parameter can be displayed in the display 14. <IMAGE> |
