Multi-axis motion control card with absolute coded disk reading function

Abstract

The invention discloses a multi-axis motion control card with absolute coded disk reading function, which comprises eight functional modules, wherein the information processing module is the core of the motion control card, receives state information of other modules, performs the corresponding control algorithms, judges system states and outputs control signals; the information processing moduleis connected with other seven functional modules; the logic protection module detects and judges the state of the system to ensure safe and reliable operation of the system; the local area network control module is utilized to the communication among a plurality of cards; the data exchange module is utilized to the real-time communication between the motion control card and an upper computer; theanalog quantity signal monitoring module receives the speed of the controlled motor and torque analog signals; the coded disk signal reading module receives the motion position information of the controlled motor; the position-control pulse width modulation wave signal producing module outputs position control signals; and the analog control quantity output module outputs the analog control signals of the speed and the torque. The multi-axis motion control card is suitable for the control of multi-axis linkage equipment.

Description

technical field [0001] The invention relates to the technical field of automation control, and relates to a multi-axis motion control system, in particular to a motion control card for controlling multi-axis motion. Background technique [0002] The motion control card is a control device that coordinates and controls the target device or equipment driven by a motor to make it move according to the expected operating trajectory. In occasions such as series-parallel robots that require multi-axis coordinated motion, a multi-axis motion control card is required. Multi-axis motion control cards are widely used in automation equipment, especially in CNC processing equipment and series-parallel robots, and are the core technical equipment in the electronics and machinery manufacturing industries. It is characterized by a large number of control axes and a relatively high requirement for synchronization. [0003] At present, there are many kinds of mature multi-axis motion contr...
