A numerical controller includes a main control unit configured to analyze a program and a motor control unit configured to control a motor. In the case where motor control data is transferred from the main control unit to the motor control unit via a serial bus, instead of transferring all pieces of the motor control data to each shaft one by one, when the motor control data repeats a specific pattern, the repetition pattern and the number of repetitions are transferred, and the repetition pattern is duplicated in the motor control unit.

A numerical controller capable of temporarily executing dedicated function software includes a dedicated function software reading unit configured to read, in response to a reading condition being satisfied, the dedicated function software into a primary storage area mainly accessed by a CPU, dedicated function software execution unit configured to execute the dedicated function software as a process in response to an execution condition being satisfied, and a dedicated function software termination unit configured to stop execution of the process of the dedicated function software and delete the dedicated function software from the primary storage area in response to a termination condition being satisfied.

A machine tool controlled by a numerical controller includes a feed handle for driving a drive-shaft for moving a tool and a workpiece relatively by using a mechanical mechanism and a motor for driving the drive shaft. The numerical controller generates an automatic feed command for driving the motor when a specific handle operation performed on the feed handle is detected.

A sequential program is divided into programs each with a size fitted into a cache memory using program profile information and prepared cache memory information. Program profile information on the sequential program and information on the cache memory are acquired. Based on the acquired information, division addresses at which the sequential program is divided are determined. The IDs of the division programs, assigned core numbers, the start addresses and end addresses of the programs, and cache storage block information are stored in a memory as program execution information.

Step data are sequentially read out from a conversational program created in a conversational format. The processordetermines whether or not leaning control in the step is possible. When the leaning control is possible, a learning start command is added to the start of the program to create and output an NC program in the step. Also a learning end command is added to the end of the NC program in the step. Conversion into the NC program is performed for each of steps. When a learning control automatic ON/OFF operation is selected to all the steps, a learning control start command and a learning control end command are added to the start and the end of the converted NC program when learning control of all the steps can be performed.
