Technical Architecture & Functional Positioning

The HMV01.1R-W0120 module is a high-performance proportional interface for hydraulic control, positioned at the control layer within IndraDrive and IndraMotion systems. It converts digital control commands into precise hydraulic valve operations with minimal lag and high repeatability.

The module features advanced DAC-based proportional output, isolation amplifiers, and thermal protection circuits, ensuring precise actuator positioning even under dynamic load changes. Its design includes redundant signal paths and fault detection circuits, allowing the system to continue operation during partial failures, essential for high-availability industrial and mobile hydraulic applications.

Engineering advantages:

• Enhanced System Reliability: Fault-tolerant design minimizes production downtime and actuator errors.
• High-Speed, High-Precision Control: ≤1.5 ms response time allows precise motion control in fast dynamic processes.
• Simplified Integration: Standardized CANopen/EtherCAT interfaces enable plug-and-play installation with IndraMotion/IndraDrive controllers.
