Abstract: After a controller #1 has started giving an interpolating instruction, the length on an interpolation line is calculated by a first calculation means in synchronism with a clock signal from a clock synchronous circuit 45, and after having executed a first step for generating a synthetic locus-use frame 100 based upon the calculated value, the synthetic locus-use frame 100 is transmitted to controller #2 so that, after controller #2 has executed a second step for receiving a synthetic locus calculation-use frame from a receiving means, controllers #1, #2 execute a third step for calculating the position on the interpolation line based upon the synthetic locus-use frame 100 by using a second calculation means.

Abstract: A servo system controller which has a sequence controlling section 2 and a servo controlling section 3, employs not only a current position of a servo motor but also other servo control data or a sequencer device as comparison data, and executes a comparing process for compares whether or not respective comparison data are in respective detection ranges to then output respective comparison results, increase and variation of a response time can be prevented until the comparison results are output from the change of the comparison data. A comparing process table memory 14 is provided in the servo controlling section 3, and the comparing process is executed in synchronism with a calculation period of the servo controlling section 3, and a detection signal is output while the comparison data is within a detection range. In a machining apparatus utilizing the servo system controller, a tact time can be reduced without large increase of a cost.

Abstract: In a servo system controller comprising a servo control section, a sequence control section, and a dual port memory, an event detecting unit for detecting generation of an event according to input information from an object to be controlled and an event processing program memory are provided in the servo control section, and an event processing program is executed by the event processing program memory upon interruption by the servo control section according to an output signal from the event detecting unit.

Abstract: A servo control method is realized by connecting a high-speed serial communication interface with a microcomputer, a dual port memory and an IC for high-speed serial communication mounted thereon to an extended bus of a personal computer and by connecting between the high-speed serial communication interface and a plurality of servo controllers with a serial line in a multi-drop system.

Abstract: A drive control commanding unit is provided which, when plural such units constitute a system, can configure the system as a synchronous system which can conduct a synchronous operation free from synchronism deviation. The drive control commanding unit has an operation clock generator 9 which generates an operation clock signal, an interruption generator 11 which outputs an interruption signal at every cycle of the operation clock signal.
