Patent ID: 7081731

Claim:
A translatory actuator unit comprising: a translatory actuator module that moves an object straightly; a force sensor that detects a load applied to the translatory actuator module; and a servo control module that controls a speed, a position and/or output power of the translatory actuator module, wherein the translatory actuator module, the force sensor and the servo control module are integrally configured, the servo control module has two-way network means for receiving a control command concerning the speed, the position and/or the output power from a network, and transmitting information of the speed, the position and/or the output power to the network, control means for controlling the speed, the position and/or the output power, and self-diagnosis means for confirming safety and detecting an abnormal state based on detected information of the speed, the position, the load, and/or an electric current of the translatory actuator module.
