The invention relates to a method for operating a drive and a drive, wherein the drive comprises at least one motor having a rotor shaft that can be loaded by a brake torque created by at least one brake comprising a powered brake coil, wherein the brake coil is arranged in series with two switches by which the coil current can be controlled, wherein the first switch is activated by a first control circuit and the second switch is activated by a second control circuit, wherein the switches are opened to produce the unpowered state of the brake coil and one of the two switches periodically receives a control signal, particularly briefly, to attain the closed state in this period, wherein an inspection of the effect of this respective control signal takes place and, in the case of a negative result of the inspection, warning information is output and/or the drive is transferred to a secure state and/or deactivation of the drive is carried out.
