摘要： A system for path command generation includes an industrial machine, an interface accessible via a remote device, and a server communicably coupled to the industrial machine and the remote device via a network. The server includes processing circuitry configured to calculate an optimum path command, simulate the optimum path command based on the calculation of the optimum path command, calculate a cycle time and error of the path command, determine if the path command is acceptable, and transmit path command data to the industrial machine in response to the acceptable path command being selected.

摘要： A positioning control device according to an embodiment includes an amplifier that includes a converter that rectifies and outputs an AC power supply to bus-bars; a smoothing capacitor that smoothes an output of the converter and generates a bus voltage; a regenerative resistance and a regenerative transistor; an inverter that supplies a drive current; and a command generation unit that generates a position command value for positioning control of a mechanical load in accordance with a command pattern. The inverter is connected between the bus-bars and supplies the drive current. The command generation unit acquires a regenerative-power-amount estimated value and an energy value storable in the smoothing capacitor; and on the basis of a result of a comparison between these values, it decides whether to use the position command value on the basis of the command pattern.

摘要： An apparatus for controlling conveyance between rollers includes: a tension-control-amount-detector; a speed-shaft-speed-controller; a tension-shaft-speed-controller; a synchronous-speed-command-generation-unit synchronizing the speed-shaft speed command with a tension-shaft reference speed command; a tension-control-calculation-unit outputting a tension-control correction value based on proportional compensation based on a proportional gain, and integral compensation based on an integral gain; an adjustment-execution-command-generation-unit outputting an adjustment execution command during an automatic adjustment period; a binary-output-unit outputting one of positive and negative values of the additional-value amplitude as an additional value in adjustment during the automatic adjustment period; a tension-shaft-speed-command-generation-unit outputting a tension-shaft speed command based on the tension-shaft reference speed command, the tension-control correction value and the additional value in adjustment; and a gain-calculation-unit calculating a proportional gain and an integral gain based on a period and an amplitude of the tension control deviation for the automatic adjustment period.
