System Architecture & Signal Flow
The VT-HACD-DPQ-1-20/V0/1-0-0 operates as a standalone axis controller within the Rexroth VT-HACD modular rack. Command signals (analog ±10 V or digital setpoint via fieldbus) are received by the onboard DSP, which executes the configured PID/cascade control algorithm. The computed output drives the proportional valve amplifier stage (DPQ dual-channel output), which directly actuates the hydraulic proportional or servo valve. Actual position/velocity feedback is acquired via encoder or analog transducer inputs, closing the control loop at the card level. Status and fault signals are routed to the host PLC via discrete I/O or fieldbus interface.

Technical FAQ
Q: Is the VT-HACD-DPQ-1-20/V0/1-0-0 compatible with Rexroth IndraControl platforms?
A: The VT-HACD series is designed as a standalone hydraulic axis controller. Integration with IndraControl PLC platforms is achieved via analog I/O or fieldbus (platform-specific). Consult Rexroth application documentation for your specific IndraControl variant.
Q: Can this card control servo valves as well as proportional valves?
A: Yes. The DPQ output stage supports both proportional and servo valve types, subject to valve current/voltage rating compatibility. Parameterization via commissioning software is required to match valve characteristics.
Q: What is the difference between VT-HACD-DPQ-1-20 and other VT-HACD variants?
A: The DPQ-1-20 designates a single-axis, dual proportional valve output configuration with a 20-slot rack position assignment. Other variants may differ in axis count, output configuration, or rack slot designation.
Q: Do you provide commissioning support?
A: Yes. Konmask technical engineers can provide remote commissioning guidance, parameter file templates, and wiring diagrams for standard VT-HACD applications. Contact support@konmask.com.
Q: What is the lead time for R901054664?
A: In-stock units ship within 3–5 business days. For out-of-stock inquiries, lead time is confirmed at quotation stage, typically 2–6 weeks depending on source availability.
