When the spindle load value exceeds a threshold value, a speed calculation unit of the numerical controller calculates an override for the feed rate of the axis instructed by command data such that the load value of the spindle becomes constant, and, at the start of the speed calculation process, assigns the override just before the start of the speed calculation process to an initial value of an integral term or an offset for PID control."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Numerical controller for controlling feed rate based on spindle load","description":"A numerical controller performs PID control to control the move speed of an axis for driving a spindle such that a load value of the spindle becomes constant.
