A converter device (15,16) is assigned to each control lead (12,13). Signals can be fed to the control leads of the corresponding converter device . Output signals (17,18) of the converter devices can be fed to an evaluation device (19). The drive is controlled according to an output signal of the evaluation device. The evaluation device acts on the switch assigned to the control leads. Between the evaluation device and the switch is connected a control device (21) which generates control signals for the switch from the output signal of the evaluation device. |
