3. Working Principle
Command Reception & Signal Processing
The module receives real-time position, pressure, speed and flow setting commands from upper systems, and collects actual operating feedback signals from on-site sensors simultaneously. Internal high-precision filtering eliminates electromagnetic interference and noise, purifies input data and calculates deviations between set values and actual operating data accurately to provide reliable basis for closed-loop calculation.Closed-loop Calculation & Drive Output
Based on preset control modes, the 2X enhanced high-speed computing algorithm executes adaptive PID regulation, ramp smoothing, valve compensation and dynamic load correction. Output power and driving current are adjusted precisely in real time and amplified by internal power circuits to drive hydraulic proportional and servo valves accurately. Operational deviations are corrected rapidly to realize stable and high-precision dynamic follow-up control of hydraulic pressure, speed, position and flow.Bus Interaction & Multi-axis Coordinated Control
Two-way real-time data exchange is realized with upper control systems via E23 high-speed bus. Module operating status, output parameters, hydraulic data and fault information are uploaded continuously while control commands are received instantly. Multi-module clock synchronization enables precise coordinated movement of multi-axis equipment, meeting synchronous control requirements of complex automatic production lines and sophisticated processes.Real-time Monitoring & Intelligent Fault Protection
Power voltage, output current, module temperature, bus connection, load condition and signal transmission are monitored throughout operation. Once faults including overcurrent, overvoltage, overtemperature, short circuit, signal breakage, abnormal load and bus failure are detected, fault codes will be locked automatically, power output cut off and audible and visual alarms triggered to protect valves, modules and complete equipment and prevent fault escalation.Online Debugging & Maintenance Optimization
Online parameter tuning, real-time waveform observation, dynamic parameter optimization and automatic zero calibration help obtain optimal control parameters rapidly for different working conditions. Large-capacity built-in fault log stores long-term operating and fault data, facilitating quick troubleshooting, equipment status analysis, efficient maintenance and continuous performance improvement.4.
