Abstract

The invention provides an electronic cam control device which comprises a servo drive module, and the servo drive module comprises a position ring. The electronic cam control device further comprises a reference position obtaining module and an electronic cam module, wherein the reference position obtaining module is used for obtaining the position of a main axle, and the electronic cam module calculates the running position of an auxiliary axle according to the position of the main axle and inputs the running position of the auxiliary axle to the position ring of the servo drive module. The servo drive module outputs control signals to a servo motor according to the input of the position ring. The invention further provides a corresponding method. According to the electronic cam control device and the corresponding method, acquisition of the position of the main axle, interpolation calculation, and servo drive are integrated, unreliable factors in instruction transmission are reduced, reliability of the electronic cam control is enhanced, and cost is saved.

Description

technical field [0001] The invention relates to the field of servo motor control, in particular to an electronic cam control device and method with motion control function. Background technique [0002] Electronic CAM (Electronic CAM) is an intelligent controller that simulates a mechanical cam. It feeds back position information to the processing unit through a position sensor (such as a resolver or an encoder, etc.), and the processing unit decodes the received position signal. Computational processing, and set and output the level signal at the specified position according to the setting requirements. Electronic cams can be used in various fields such as automobile manufacturing, metallurgy, machining, textiles, printing, food packaging, water conservancy and hydropower. [0003] With the continuous upgrading of industrial automation and the increasingly complex process of automation products, in order to meet the requirements of special shape and process, it is often ne...
