System Initialization & Parameter ConfigurationAfter connected to industrial automatic control systems and powered on, Rexroth VT-MVTW-1-16/D automatically completes self-check and initialization to inspect the working state of internal circuits, signal interfaces and redundant units, and enters ready state without abnormalities. Engineers adopt programming languages such as Ladder Diagram, ST and FBD via upper programming software to compile control logic, set control parameters including position, speed and acceleration thresholds, feedback signal acquisition modes and redundant operation modes, so as to finish matching between the module, field devices and upper systems.
Feedback Signal Collection & AnalysisThe module collects real-time operating feedback signals such as position and speed signals from on-site sensors and actuators through signal input ports. Internal digital signal processing technology filters interference and verifies data to accurately analyze signal information and judge deviations between actual system operating status and preset targets.

Control Calculation & Command OutputBased on preset control logic and analyzed feedback signals, the module conducts operation via internal control algorithms to generate accurate control commands and adjust output parameters. The commands are transmitted to actuators like hydraulic cylinders and hydraulic motors through signal output ports to correct system operation deviations, ensuring actuators run in accordance with preset position, speed and acceleration and realizing high-precision closed-loop control.
Redundant Switchover & Fault Tolerance GuaranteeThe module adopts redundant design, in which main unit and standby unit synchronize operating data and control parameters in real time. Once the main unit suffers faults such as circuit damage and signal disconnection, the standby unit will take over all control functions seamlessly to keep system running normally and avoid production interruption. Meanwhile, the built-in fault detection mechanism monitors operating status all the time to discover and avoid potential risks timely.
Status Monitoring & MaintenanceThe module monitors its own operating condition, signal transmission status and field equipment running state in real time, and uploads operating data to upper systems for remote monitoring by engineers. It supports regular diagnostic inspection, through which staff can view module operating parameters and fault records via upper software to troubleshoot problems timely, conduct routine maintenance and keep the module in optimal working condition.
