Abstract
A numerical control device for controlling rotation of a servomotor in response to numerical control data to move a movable member by a commanded feed amount at a commanded feed rate. A velocity detector detects an actual feed rate of the movable member. A register stores an allowable feed rate data. A comparator compares an allowable feed rate data from the register and an actual feed rate from the velocity detector to output an abnormal signal when the actual feed rate exceeds the allowable feed rate. The allowable feed rate data is set into the register each time the commanded feed rate is changed.
