摘要： The finding refers to the field of industrial automation, and in particular regards a stand-alone apparatus for commanding and controlling the functions of an actuator for industrial use.
The apparatus, enclosed in a single container (14), commands and controls the functions of an actuator (5), by means of an actuation and verification device (10), while a plurality of detection and evaluation members (8, 15a, 15b, 15c) obtain a plurality of parameters indicative of the functionality of the actuator (5) and the relative actuation system in order to verify the correct functioning thereof. The apparatus also comprises a command and control unit (2) connected to the actuation and verification device (10) as well as to the plurality of detection and evaluation members (15a, 15b, 15c) in order to coordinate the functioning thereof and to cyclically execute a self-diagnosis function.

摘要： An actuator control system (10) includes an actuator (40) continuously movable between multiple positions. A controller (18) is configured to command the actuator to a desired actuator (40) position and to apply the command to an actuator model (24). The controller (18) is configured to compare the modeled and actual actuator positions to determine if the position difference exceeds a fault detection accommodation limit and if the position difference is within a band that is different than the fault detection accommodation limit. The controller (18) is configured to calculate a threshold (30), which is based upon an estimated load on the actuator (40). The controller (18) is configured to calculate a band comprised of the threshold (30) applied to the modeled position and to determine if the actual actuator position is within the calculated band. The threshold (30) is calculated at regular intervals, and a fault is declared if the actual actuator position is outside the band for a number of consecutive intervals.

摘要： In a hydraulic unit (A) including a hydraulic pump configured to be driven by a motor (2) and a hydraulic cylinder (3) for actuating a chuck, a fixed displacement hydraulic pump is combined with an adjustable speed motor (2) for driving the pump. In order to concurrently provide rapid movement of the cylinder (3) and reduction in the surge pressure, upon the cylinder (3) actuating the chuck, after a teaching movement is imparted to the cylinder (3) to determine an operating stroke of the cylinder (3) based on the number of rotations of the motor (2), the motor (2) is rotated at a high rotational speed for movement until a preset deceleration start point short of the end of movement of the cylinder (3) within the determined operating stroke and then rotated at a low rotational speed for deceleration from the deceleration start point to the end of movement of the cylinder (3), thereby allowing the chuck to chuck a work with a soft touch.

摘要： A hydraulic pressure control apparatus includes an upstream control valve, a downstream control valve, a hydraulic pressure sensor, and a controller. The upstream control valve is provided between a hydraulic pressure source and a hydraulic pressure device. The downstream control valve is disposed between the upstream control valve and the hydraulic pressure device. The hydraulic pressure sensor is configured and arranged to detect the hydraulic pressure on a downstream side of the downstream control valve. The controller is configured to control the upstream control valve and the downstream control valve based on an upstream pressure command value and a downstream pressure command value, respectively. The controller is further configured to detect an abnormality in the upstream control valve based on the hydraulic pressure detected by the hydraulic pressure sensor when the downstream pressure command value is set to be equal to or greater than the upstream pressure command value.
