    Abstract: A secure certificate is provided to enable features within a motor drive. The certificate enables secure delivery of features for execution on the motor drive. A private key is stored in the motor drive, and the secure certificate is encrypted by the supplier with a corresponding public key. The encrypted certificate is delivered via a secure channel to the motor drive. The motor drive decrypts the certificate and reads the desired features for inclusion in the motor drive from extensions defined within the certificate. The motor drive downloads instructions for execution on the motor drive as well as configuration parameters required to execute the desired features. The instructions and parameters are stored in the memory of the motor drive for subsequent execution. Identification of features by secure certificate allows for feature and time-based licensing of functions for execution by the motor drive.
