In a level shifter, in the case where the amplitude voltage of an input signal (i.e., a first power voltage VDDL) input to an input terminal is changed to be higher and the amplitude voltage of an output signal (i.e., a second power voltage VDDH) output from an output terminal is changed to be lower, a fall delay time of the signal output from the output terminal tends to be longer than a rise delay time of the signal. However, an inverted input signal obtained by an inverter is input to a level shifting unit and also to the gate of an N-type transistor, and therefore, the N-type transistor is turned on at the fall of the input signal input to the input terminal, so as to supply a current based on the second power voltage VDDH to an output node of the level shifting unit for assisting the shift into H level performed in the level shifting unit. Accordingly, even when at least one of the amplitude voltage of the input signal and the amplitude voltage of the output signal is changed, balance between the fall delay time characteristic and the rise delay time characteristic of the output signal can be satisfactorily kept.

A method of operating a controller of an industrial machine capable of reducing a rise in temperature of a processor, easily restoring and resuming the operation even if the operation is stopped by the rise in temperature, and further possibly preventing the stop of the operation of the controller by the rise in temperature. When temperature in the controller is lower than a set value, the processor performs a plurality of processings in each predetermined period to do normal operation. When the temperature rises to a set value or higher, processing related to the controlling axes is stopped, a motor is stopped, and the processor performs only minimum or limited required processing, i.e., processing related to a man / machine interface such as processing related to a programmable controller and processing for display and operates in a low-electric-power consumption mode except the period when the processor performs the minimum or limited required processing. In addition, as the temperature rises, the operating speed of a machine controlled by the controller is reduced to reduce heat generation and the rise in temperature of the processor.
