Abstract
Provided is an electrical drive for an industrial robot, wherein each driver circuit for the associated power switches of the first half-bridge is designed, in the case of a voltage-free or current-free state of the associated control input, to put the power switch associated with the control input into a non-conductive state, each driver circuit for the associated power switches of the second half-bridge is designed, in the case of a voltage-free or current-free state of the associated control input, to put the power switch associated with the control input into a conductive state, and a switching device is provided, which is designed, with the safety signal for the forced switch-off of the rotating-field voltage, to simultaneously switch the control inputs of the driver circuits for all power switches of the inverter into a voltage-free and/or current-free state.
