  • Drive system using a servomotor with a memory
    Patent number: 6211639
    Abstract: A drive device regulates a servomotor to one of a predefined position, a predefined speed, and a predefined current setpoint value. A control module is connected upstream from the drive device. A non-volatile memory where motor-specific data is stored is arranged in the housing of the servomotor. The housing has a data output through which the motor-specific data can be read. The motor-specific data is transmitted over a data line over which the feedback signals delivered by a sensor associated with the motor are also transmitted.
