Abstract

The invention provides a servo motion control integrated machine system for a flying saw machine, belonging to the technical field of automatic control. The system comprises a rectifier circuit, a filter circuit, a brake circuit, a switch power supply circuit, a protection circuit, an inverter circuit, a current sampling circuit, an encoder circuit, a PWM drive circuit, a CPLD circuit, a DSP circuit, a power down memory circuit, a communication control circuit and an I/O interface circuit. The system has the advantages that the problems of oscillation, instability and even out of control of a flying saw actuator which is a servo motor caused by control signal introduction interference caused by different ground potentials of two devices are solved. The production precision is improved. The reliability is enhanced, and the response speed is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a servo motion control integrated machine system used on a flying saw machine. Background technique [0002] The flying saw machine is a common equipment for continuous online cut-to-length cutting of various pipes and profiles, and the application of the servo system meets the production needs of high precision and high standards. In the prior art, the control of the servo motor in the flying saw control system is accomplished jointly by the servo driver and the flying saw motion controller. According to the length requirements of the cut pipe and profile, the flying saw motion controller detects the current production speed and length of the pipe, calculates and outputs the motion control signal, so that the flying saw moves according to the expected motion trajectory and specified motion parameters. The servo motor is the actuator of the flying saw motio...
