Product Description (Detailed Explanation)

The VT-VPCD series represents a high-end digital “brain” for hydraulic pumps. It integrates swivel angle control, pressure control, and power limitation into a single electronic unit.

The module processes analog and digital command values and compares them with actual feedback from transducers (swivel angle and pressure). The internal microcontroller then executes complex algorithms to drive a proportional valve, which adjusts the pump’s swash plate to the precise required position. The /V0 version indicates a standard version with a serial interface for parameterization via BODAC software.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Integrated Power Limiting: Automatically calculates and limits pump power ($P \approx Pressure \times Flow$), protecting the electric motor from overload.

• Non-Volatile Storage: All parameters and 16 pre-definable command value sets are stored in FLASH memory, ensuring they are not lost during power outages.

• Precise Control: Digital processing eliminates the “drift” associated with older analog cards, providing highly repeatable and stable pump performance.

• Real-time Diagnostics: The front-panel display and LEDs provide immediate feedback on faults such as cable breaks, short circuits, or system deviations.

• Modular Versatility: The Euro-card design allows for easy installation into standard Rexroth card holders (like VT 3002).

Precautions (Important Notes)

• Electrostatic Discharge (ESD): This is a sensitive electronic PCB. Always use an ESD wrist strap during handling to avoid damaging the microcontroller.

• Wiring Polarity: Ensure the 24V DC supply is stable. While it has a high tolerance (+40%), voltage spikes outside this range can damage the switching power supply unit.

• Shielding: Feedback signals from the pump’s inductive position transducer must be carried via shielded cables to prevent electromagnetic interference (EMI) from the solenoid outputs.

• Hot-Plugging: Do not plug or unplug the card while the rack is powered. This can cause arcing at the 64-pole connector and lead to logic errors or hardware damage.

Product Applications (Typical Use Cases)

• Industrial Press Systems: Precise control of flow and pressure for heavy-duty metal forming or plastic injection molding.

• Hydraulic Power Units (HPUs): Managing multi-pump systems where power sharing and limitation are required to prevent grid overload.

• Civil Engineering: Controlling large axial piston pumps used in tunnel boring machines or heavy lifting equipment.

• Marine & Offshore: Governing the pitch control or winch systems on ships where variable displacement pumps are the primary power source.

• Test Benches: Providing highly accurate and repeatable hydraulic flow/pressure cycles for component endurance testing.
