Technical Architecture & Functional Positioning

The HMV01.1R-W0065 module is a digital-proportional interface for hydraulic control systems, designed to provide high-speed, accurate actuator control. Its primary role in the system is at the control layer, translating digital commands from IndraMotion or IndraDrive controllers into precise hydraulic valve movements.

Its architecture integrates high-speed DACs, isolation amplifiers, and thermal protection circuits to maintain accurate flow control under varying load and environmental conditions. The module supports redundant signal pathways and incorporates self-diagnostic and overcurrent protection to minimize the risk of failure, ensuring operational continuity in critical industrial applications.

From an engineering perspective, these design features address several challenges:

System Reliability: Redundant and isolated circuitry prevents actuator misbehavior during voltage fluctuations or partial hardware faults.
High Precision Control: Fast response time (≤1.8 ms) ensures accurate positioning in dynamic hydraulic systems.
Field Commissioning Efficiency: Standardized communication protocols (CANopen/EtherCAT) allow easy integration with existing Rexroth automation systems.
