Working principle

The YASKAWA LASC-100SUB core is based on the working logic of "instruction reception trajectory planning multi axis collaboration position feedback closed-loop control". As the core control unit of high-precision multi axis motion control system, its core function is to convert the motion instructions of the upper controller into accurate multi axis control signals, drive multiple servo motors to cooperate to complete the preset motion trajectory, and achieve motion state closed-loop control through high-precision encoder signal acquisition, ensuring nanometer level positioning accuracy.

The specific workflow is as follows: Firstly, the upper controller issues motion control instructions (including control mode, target position, motion speed, trajectory type, and other parameters) to the control signal input terminal of YASKAWA LASC-100SUB according to the job requirements; The internal control unit of the module parses the received instructions and generates the optimal motion trajectory through the built-in high-precision trajectory planning algorithm. Combined with multi axis synchronous control logic, the control signal is distributed to the servo drive interface of the corresponding axis; Each axis servo motor starts running according to the control signal, and the accompanying high-precision encoder feeds back real-time motion status signals (position, speed, phase) to the encoder interface of the module; The module synchronously collects and analyzes multi axis feedback signals, compares them in real-time with preset target trajectory parameters, and dynamically adjusts the control signals of each axis through closed-loop control algorithms to ensure the synchronization and positioning accuracy of multi axis motion; Throughout the entire working process, the built-in protection monitoring module continuously monitors the power supply status, output signals, and its own temperature rise. When abnormal working conditions such as overcurrent, overvoltage, and excessive position deviation are detected, the control circuit is immediately cut off, and an alarm signal is output and fed back to the upper controller; In addition, the enhanced anti-interference design of the module ensures stable transmission of control signals and feedback signals in the strong electromagnetic environment of industrial sites, avoiding signal distortion and reducing control accuracy, ensuring the ultra-high precision and stable operation of the system.
