Abstract
A method for providing motion information for a motor controller is accomplished by defining a determined set of motion parameters for describing a desired motion in terms of encoder position data. The parameters are stored for use in calculating the desired motion profile of the motor during the various motion segments of the desired profile as the motor is being driven. The method saves on required memory storage for all the various motor profiles typically used in devices such as inserters since only the parameters used in calculating must be stored. A flag field is also provided to enable the microprocessor to determine which of the segments is being generated.
Claims6
A method for providing motion information for a motor controller for a motor having an encoder for providing motor feedback data, the method comprising the steps of:
- (a) converting a conventional distance formula means into at least one incremental encoder position formula means;
- (b) determining a set of motion parameters for the encoder position formula means for a plurality of linear segments of a motion profile;
- (c) storing the set of motion parameters;
- (d) determining motor drive information using the set of motion parameters and the encoder position formula means for control of the motor during operation of the motor;
- and
- (e) driving the motor in accordance with the determined information.
