Patent number: 5859515Abstract: 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.Type: GrantFiled: September 19, 1997Date of Patent: January 12, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yoshichika Takizawa, Yasuyuki Suzuki, Misako Okada, Makoto Nishimura, Hidehiko Matsumoto, Yasuharu Kudo, Tohru Tsujimoto

Patent number: 5642024Abstract: 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.Type: GrantFiled: January 27, 1995Date of Patent: June 24, 1997Assignees: Mitsubishi Denki Kabushiki Kaisha, Mitsubishi Electric Engineering Co., Ltd.Inventors: Misako Okada, Makoto Nishimura, Hidehiko Matsumoto, Yuko Tomita, Yasuharu Kudo

Patent number: 5600221Abstract: 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.Type: GrantFiled: May 5, 1995Date of Patent: February 4, 1997Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuhiko Tomatsuri, Misako Okada, Yusuke Ushio, Yuko Tomita, Satoshi Mizogami
