AC servo motor overload protection device

摘要

PROBLEM TO BE SOLVED: To solve the problem of conventional protector, with which an AC servo motor is operated in an overload condition by the error of position setting and that it causes damages to the AC servo motor or a servo driver, system downs, etc., in the case of controlling the position of a machine device, using the AC servo motor. SOLUTION: The AC servo driver is provided with an overload limiting section, and the output property is set to a minimum torque limiter value, until N1 of servo driver speed, and from N2, is set to a maximum torque limiter value.
