A location programming apparatus and method according to the present invention generates operation control information consisting of a locating control parameter and a locating program for a controller for controlling a motor for operating a subject which must be controlled, the location programming apparatus including: locating control type setting means (control S/W) for setting locating control type for controlling the operation of the subject which must be controlled; graphical data generating means (control S/W) for graphically generating graph data of the locating program on a work memory in accordance with the set locating control type; and operation control information generating means (control S/W) for generating operation control information on a parameter memory and a locating program memory in accordance with graph data stored in the work memory. Thus, a locating program and a locating control parameter can be generated by only graphically setting the locating locus operation, a speed pattern and time transition control.

Location programming apparatus and location programming method

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.

Servo system controller

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.

Servo control method and servo control system

An apparatus for synchronously controlling the actual operation of a machine using one or more motors, such as servo motors, by simulating in program form a combination of selectable machine mechanisms, including drivers, connecting shafts, clutches, gears and cams. Each such machine mechanism is represented by a virtual mechanism, preferably as a software module that contains information uniquely identifying the module, operation information that defines the generation of position information and connection information that defines other modules to which connection is made. The software modules comprise drive modules for generating position information, transmission modules for simulating the transmission mechanisms and output modules for outputting motor commands.

Positioning and control apparatus that is interactively programmable

A positioning apparatus and method for synchronously controlling a plurality of motors, such as servo motors, and exercises synchronous control by means of only motors without using any mechanisms, such as coupling shafts, clutches, gears and cams. A controller has a virtual drive capability which provides a virtual cam and virtual clutch capability on the basis of stored values, permitting continuous and repeated operation of a single cycle of positioning with respect to changes in input axis position address data without recalculation of command addresses in real time.

Positioning apparatus and method with virtual transmission

A control apparatus for a servo system uses a servo motor to perform operations equivalent to those of a cam mechanism. A motion command section has two data tables which are used to calculate and output a position command and a velocity compensation command equivalent to a cam stroke. A servo drive section makes velocity compensation and current compensation on the basis of position and velocity compensation commands. The motion command section, alternatively, may have three data tables for the calculation of the compensation commands. In addition, multipliers are used to adjust the weight of the compensation commands. Rather than the data tables being present in the motion command section, they may be placed in the servo drive section. Formulae representing the mechanical characteristics of the cam system may be used in place of the data tables.
