Servo drive system and servo drive method for numerically controlled tool rest
InactiveCN102621926AReduce interfaceReduce the amount of programmingNumerical controlEngineeringMotor control
The invention relates to a servo drive system and a servo drive method for a numerically controlled tool rest. The system comprises a numerically controlled upper computer, a servo driver, a tool rest popup and withdrawal mechanism, a servo motor and a tool rest device. The numerically controlled upper computer sends out tool changing orders including a target position of an appointed tool rest. The servo driver receives the tool changing orders, calculates the rotation direction and distance of the tool rest according to the current position and the target position of the tool rest, controls the tool rest popup and withdrawal mechanism to pop up the tool rest and generate motor control signals to the servo motor so as to control the tool rest to rotate to the target position, and controls the tool rest popup and withdrawal mechanism to withdraw the tool rest. The servo driver of the servo drive system directly receives the tool changing orders to generate internal position orders instead of receiving the pulse-form orders generated by the numerically controlled upper computer, so that inaccuracy in positioning caused by loss of pulse orders can be avoided. Further, programming quantity of the numerically controlled upper computer is reduced, and a tool rest controller is omitted.
