Abstract
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.
