切換装置。 A drive motor for each of the two axes driven from the NC side via a controller, a detection means for detecting the current value of the drive motor, a multi-amplifier that takes in the signal with the detection means, and a multi-amplifier for the multi-amplifier. A multiplexer with a selection function that selects a load value according to a command from the M code data stored in the NC machining program data memory, and an upper limit based on the load value from the multiplexer via an A/D converter. a calculation means for each axis for setting values and lower limit values; a memory for storing the upper limit value, lower limit value, or load value set by the calculation means for each axis; and upper and lower limit values stored in the memory. It is comprised of a judgment means for comparing heavy load and light load by comparing the load values after the first time, and if the judgment means determines that each load value is higher than the upper limit value, the driving speed is decreased, and each load value is set to the lower limit value. An input switching device for monitoring a drive shaft load, which increases the drive speed if the drive speed is lower.
