Method for transferring data of motor controller of combustion engine, involves providing modulated negative voltage pulse to control connection of motor controller as data information

摘要

The method involves generating positive voltage pulses and negative voltage pulses during active pulse phases and during inactive pulse phases, where negative voltage pulses modulates during the active pulse phases and during the inactive pulse phases. The modulated negative voltage pulse is provided to a control connection (16) of a motor controller (2) as data information, where multiple electronic components (D1 to D6) assigned to the control connection are switched-on or -off for modulating the data information. An independent claim is included for a motor controller for a combustion engine, particularly of a hand-operated working unit.
