A motor driving amplifier and a numerical controller are connected to each other via communication to configure a numerical control system. The numerical controller includes a numerical control unit, a motor control unit, and an amplifier interface unit. Furthermore, a motor control processor included in the motor control unit is a multi-core processor.

Numerical control system having multi-core processor

A numerical controller and a servomotor control system, capable of axis control required in case of a communication failure in the control of servomotors driven by servo amplifiers connected to a plurality of serial buses. The numerical controller has a plurality of serial buses to which the numerical controller and a plurality of servo amplifiers are daisy-chain-connected and controls servomotors connected individually to the servo amplifiers. The device comprises a plurality of communication control circuits for detecting respective communication failures of the serial buses and selecting means for selecting whether or not to notify the other communication control circuits of a communication failure, if any, of any one of the communication control circuits detected thereby. In the control of the servomotors driven by the servo amplifiers connected to the serial buses, an output of a servo amplifier connected to a serial bus that suffers a communication failure is reduced to 0 so that outputs to the servo amplifiers connected to the remaining normal serial buses can be maintained.

Numerical controller and servomotor control system

In a master unit, clock signals from a clock are counted by a counter, and clock data is generated. This clock data is outputted to a slave unit by a driver, and stored in clock data storage memory. The slave unit stores clock data received by a receiver in the clock data storage memory. A processor for a program controller of the master and slave units starts up, and executes the synchronized operation of an operating program of axes that are synchronized on the basis of clock data stored in the clock data storage memory. It is also possible to commence operation of an axis under other conditions without relying on clock data. If override is applied to clock data, override will apply only to an axis that is synchronized and operated in accordance with clock data.

Numerical control system

An robot control apparatus with a teaching operation panel capable of making graphic display. The teaching operation panel comprises a processor, a flash memory, a DRAM, a communication port, a touch panel, a graphic controller for controlling a display device, a key control circuit for jog keys. The flash memory stores an operating system having small data size storable in the flash memory and supporting a graphic interface. The processor reads a robot operation program stored in a memory of the robot controller or in an external memory of the teaching operation pane and makes a graphic display on the display device. The graphic display is easily comprehended by an operator and editing and creation of the robot control program is made easy.

A numerical control apparatus allows a portion of a prototype or the like to be easily machined without an operator being concerned with a coordinate system, origins, and other data. A guidance function executing unit displays guidance information on a display unit. According to the displayed guidance information, the operator enters machining commands using a keyboard, etc. A pulse distributing unit sends present positions from present position registers to the guidance function executing unit. The guidance function executing unit calculates a movement command from command values commanded by the operator and the present positions, and sends the calculated movement command to the pulse distributing unit, which outputs distributed pulses to drive the machine tool.

Image processing apparatus using look-up tables

According to the servomotor drive control system of the invention, a processing section and a servomotor are arranged at physically separate locations. Data are exchanged via a data bus between a main CPU, which performs input data processing and sequence processing, and the processing section. As a result, servomotor drive commands and feedback data can be transferred at high speed without requiring a special interface device, and an arithmetic circuit section is separated from the environment in which the servomotor is installed.

A high-speed machining system for executing a machining program for a numerical control apparatus at high speed, in which the numerical control apparatus incorporates a hard disk drive (20) for storing a machining program for numerical control, a hard disk control circuit (15), a direct memory access control circuit (14) for transferring the machining program from the hard disk control circuit (15) to a RAM (13), and a microprocessor (12). The microprocessor (12) converts the machining program stored in the RAM (13) into minute amounts of movement for each axis and transfers the resulting data to a numerical control apparatus CNC 2. Therefore, a high-speed data transfer is possible and high-speed machining can be performed with a simple structure.

A picture processing apparatus inputs window data (W) to look-up tables (TBL) in which operators (G or F) to be applied to pixel data (x) are stored in correlation to the locations of the pixel data. By switching between the operators (G or F) contained in the look-up tables (TBL), window processing corresponding to a data address (i,j) is performed on input pixel data (x.sub.ij).
