TOOL AND METHOD FOR OPERATING A TOOL

Abstract

The invention relates to a tool (1) with a drive unit (M) for driving a tool element, at least one contact element (211, ..., 223) for transmitting electrical energy and / or electrical signals, and with an intermediate circuit (10) for electrically connecting the drive unit (M) to the at least one contact element (211, ..., 223). The intermediate circuit (10) comprises a switching module (110) for the drive unit (M) and a microprocessor module (400) for controlling and / or regulating the switching module (110).The microprocessor module (400) is configured to detect an interruption of a communication connection (S) with at least one power supply unit (910, 920) and, upon detection of such an interruption, to switch at least one switching unit (310, 320) of the intermediate circuit (10) in order to de-energize at least one contact element (211, 212, 221, 222) for the transmission of electrical energy on the tool side and to induce a current present in the intermediate circuit (10) into the drive unit (M) for the discharge of the intermediate circuit (10). The invention further relates to a method for operating a tool (1).
