摘要:
A controller includes: a plurality of first drivers that outputs a plurality of drive signals to drive a plurality of motors, respectively, and stops an output of the drive signals with a stop signal BS1; a second driver that outputs a drive signal to drive another motor, and stops an output of the drive signal with a stop signal BS2; a first transmitter R1 that transmits the stop signal BS1 to all the first drivers; a second transmitter R2 that transmits the stop signal BS2 to the second driver; and a stop signal introduction unit A1 capable of introducing separate stop signals SS1 to SS3 into the first transmitter R1 and the second transmitter R2, respectively.

A method and a device for synchronously controlling multiple printing presses or multiple units in a printing press can reduce power consumption and improve durability of motors and motor bearings. A synchronous control device for multiple printing presses includes machine shafts (11, 111) of a main printing press (A) and a sub printing press (B) respectively provided with drive motors (15, 115), and is configured to synchronously control rotation of the sub printing press (B) with respect to rotation of the main printing press (A). Here, drive motor brakes (16, 116) are attached to the respective drive motors (15, 115), and drive control devices (19, 20) respectively configured to release synchronous control of the drive motor (15) of the sub printing press (B) by a stop instruction and to start the drive motor brakes (16, 116) of both of the printing presses (A, B) are provided.

An automatic machine has a plurality of axes driven by servo motors. The controller for controlling this automatic machine confirms that a compulsory power disconnection mode is engaged, releases the brakes and starts power supply to servo amplifiers. At a prescribed time after power supply to said servo amplifiers has started, the power supply to the servo amplifiers is halted compulsorily. Alternatively, the power supply to the servo amplifiers is halted compulsorily at a prescribed time after power supply to the servo amplifiers has started and after initial movement commands have been input to the servo controllers.

A synchronous control device which is provided with drive motors (15,115) and a central control unit (12) generating a synchronous reference signal and with which the drive motor is controlled to rotate synchronously with the synchronous reference signal supplied from the central control unit, which is provided with: device motor brakes (16,116) for braking a rotation of the drive motor; machine home position detectors (17,117) for detecting a rotation phase of the drive motor; and drive controlling means (14,114) for controlling a drive motor in such a manner that at the same time when the drive braking motors are activated depending on a stop instruction supplied from the central control unit, a required rotation phase of the drive motor is stored a comparison between the required rotation phase of the drive motor and the rotation phase thereof is made at the time of restart and home position alignment of the drive motor is performed at the start of a subsequent operation.
摘要:
Dans le domaine des véhicules à guidage automatique, il est particulièrement important que les signaux de réaction relatifs à la vitesse et à l'angle de braquage soient précis et fiables. Tout écart dans ces signaux de réaction devrait être rapidement détecté et utilisé pour modifier le fonctionnement du véhicule. Un appareil (10) contrôle en permanence les signaux de sortie variant dans le temps d'une paire de résolveurs (66, 184) associés respectivement à la rotation et à l'angle de braquage des roues. La perte de l'un ou l'autre des signaux des résolveurs pendant un lapse de temps supérieur à une durée présélectionnée relative à la fréquence d'excitation et à la vitesse du véhicule se traduit par l'interruption de l'apport de puissance que reçoit un moteur électrique d'entraînement (220) et par l'actionnement des freins.
