introduction:one、X、YHow is the straightness of motion guaranteed? First of all, it should be clear,The straightness of an axis is its straightness in two planes。Such asXThe straightness of the axis is referred to inX、YSum in planeX、ZStraightness on a plane,It is like a road that neither bends from side to side nor goes up and down。 The support plate of the machine tool is carried on the guide rail,Therefore, the straightness of the guide rail determines the straightness of the movement

introduction:The servo motor has several braking modes Sometimes we are prone to electromagnetic braking,Regenerative braking,The role of dynamic braking is confused,The wrong accessory was selected。These concepts are clarified below。 Dynamic brake consists of dynamic brake resistance,In fault、scram、The mechanical feed distance of the servo motor is shortened by energy braking when the power is cut off. Regenerative braking means that the servo motor is decreasing
