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.

Claim (Index 10):
A method for operating an electrical drive for an industrial robot, in particular a drive as claimed in  claim 1 , wherein the drive comprises an inverter having a first half bridge and a second half bridge for generating a rotating field voltage from a direct voltage intermediate circuit, control electronics for generating control signals for activating all power switches of the first half bridge and all power switches of the second half bridge, and a rotating field motor fed by the inverter via a motor circuit, wherein the inverter comprises a first connection device for providing activation signals for influencing a mode of operation of the drive by a functional controller of the robot and an interface device for supplying at least one safety signal for forced switching-off of the rotating field voltage by a safety controller of the robot, wherein each power switch is allocated a driver circuit having a double-pole control input galvanically separated from the motor circuit,\n wherein a respective driver circuit for the power switches of the first half bridge, in the case of a voltage-free or current-free state of the control input, puts the power switch, which is allocated in each case to the control input, into a non-conductive state, a respective driver circuit for the power switches of the second half bridge, in the case of a voltage-free or current-free state of the control input, puts the power switch, which is allocated in each case to the control input, into a conductive state, and the control inputs of the driver circuits for all of the power switches of the inverter are simultaneously switched into a voltage-free and/or current-free state by the safety signal for the forced switching-off of the rotating field voltage.
