<P>PROBLEM TO BE SOLVED: To provide a direct-acting actuator unit capable of controlling a plurality of units and equipment through a network while including a control/diagnostic function including power control in an actuator module itself with high safety and reliability, and being easily formulated as a system with high versatility and extensibility to reduce the cost. <P>SOLUTION: This actuator unit comprises a direct-acting actuator module 12 for direct acting an object 1, a power sensor 18 for detecting a load applied to the actuator module, and a servo control module 20 for controlling the speed, position, power or the like of the actuator module, which are constituted in an integrated manner. The servo control module 20 has a bidirectional network function for receiving a control command of speed, position, power or the like from the network and transmitting the information thereof, a speed control/position control/power control function, and a self-diagnostic function for ensuring safety and detecting abnormality from the detected output, speed, position and current value of the actuator module. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
