A control system for controlling operations of a plurality of controlled devices each capable of positioning a plurality of logical axes included therein to perform operations such as welding or assembling workpieces, wherein a parallel control of the respective devices is performed by a multitask processor, control of operations such as welding which require a real-time control in its nature is performed by a real-time processor, and a communication memory is provided between the both processors for transferring therebetween required commands and data for the positioning control or the operations control.

Multitask control system

A servomotor control system for multi-axes in which a single servo-amplifier can operate m rotational speed control loops and m current control loops as well for m servomotors simultaneously, where m is a predetermined integer greater than unity, while a single positioning controller with a signal teaching box can handle n servo-amplifiers in parallel, where n is a predetermined integer greater than unity, thereby mn servomotors in total can be controlled by a single system. In the system of the invention, the multiple servomotors can be divided into groups each including up to six servomotors to be controlled as a group and independently from servomotors belonging to other groups. The system of the invention can easily be expanded by a minimum addition of servo-amplifiers and/or positioning controllers to include servomotors more than mn, in which addition of one or more teaching boxes is possible whenever they become necessary.

Servomotor control system for multi-axes

A nut runner control system includes a plurality of nut runners, a plurality of subcontrollers connected to the nut runners, respectively, for controlling the nut runners, and a master controller connected to the subcontrollers for presetting and modifying drive conditions for the nut runners and for monitoring the nut runners based on data indicating operating conditions of the nut runners and received through the subcontrollers, respectively.

Nut runner control system and method of monitoring nut runners

The output shaft of a nut runner for tightening a fastener such as a bolt is first rotated with a first torque at a first speed. When the tightening torque of the output shaft reaches a preset switching torque, the first torque first speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a second torque at a second speed. When the tightening torque then reaches a preset snug torque, the second torque second speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a third torque at a third speed. When the tightening torque reaches a preset final torque, the third torque third speed rotation of the output shaft is stopped, thus completing the tightening of the fastener.
