Abstract
If a motor becomes defective, e.g. stops running, runs too slowly, or becomes too hot, many customers demand the generation of an alarm signal, i.e. ask for an alarm device provided on the motor. The following method is used for configuring this alarm signal: At least one parameter for configuring the alarm device of the motor is inputted via a input interface (80, 82); the at least one parameter is stored in a parameter memory (74; 109); the execution of at least one routine of the alarm device provided in the microprocessor (23) is influenced by said stored parameter or by a parameter derived therefrom. The invention furthermore concerns a motor for carrying out such a method. In a motor of this kind, the alarm device can easily be configured in accordance with a customer'"'"'s present needs.
