The system comprises a voltage detection circuit 4, a current detection circuit 5, and a CPU 6A which discriminates between large and small loads by a value I2 obtained by averaging a detected current I for a current detection range and current detection period that are provided as parameters, and automatically adjusts the maximum output frequency by determining a regenerative or power running state from the detected voltage and current. By making variable the current detection range and period, and a first order lag filter time constant used in averaging the current, an optimal maximum output frequency corresponding to the load may be selected to improve the operating efficiency even when fluctuations in the load are large. Further, by limiting a speed increase in the regenerative state, it is possible to prevent a dangerous operation such as descending with the speed being increased when the elevator is accelerated in a regenerative state.

    • In a driving circuit apparatus, an input video signal is logarithmically compressed via the logarithmic converting means and outputted to the exponential converting means of the next stage. The exponential converting means outputs the inputted input video signal upon inverse logarithmically converted, to the driving means which controls the image receiving tube. Since the input video signal is logarithmically compressed via the logarithmic converting means, although in case of being inputted the high frequency input video signal for high resolution, the slewing rate does not increase, and accordingly, the wideband pre-drive circuit can be more easily built in the IC.
