ERROR HANDLING IN INFUSION DEVICES WITH DISTRIBUTED MOTOR CONTROL AND RELATED OPERATING METHODS

Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module to enable input power for the motor and provide a dosage command for operating the motor, and a second control module coupled to the first control module to receive the dosage command and operate the motor using at least a portion of the input power based at least in part on the dosage command. One of the first control module and the second control module detects an anomalous condition, and in response, disables the input power to the motor, stores diagnostic information for the anomalous condition in its internal memory, and automatically resets thereafter.
