FAQ;

Advanced Control System & PLC Integration

Q1: How to upgrade the LR2 hyperbolic power control to achieve adaptive load adjustment via PLC?
A1: The LR2 control can be upgraded with electronic proportional control for PLC integration, following these steps: ① Install a Rexroth VT-VSPA1-1-1X proportional amplifier to convert PLC signals (4-20mA/0-10V) into hydraulic control signals; ② Connect the pump’s power feedback sensor (R901500888) to the PLC’s analog input module to form a closed-loop control; ③ Use Siemens S7-1500 PLC to program adaptive logic — for example, in a crane system, the PLC adjusts the 4-20mA signal based on boom load (measured by a load cell): 4mA (10% displacement) for no load, 12mA (50% displacement) for medium load, 20mA (100% displacement) for full load; ④ Calibrate via Rexroth IndraWorks software to ensure signal linearity (error ≤1.5%); ⑤ Add a manual override switch for emergency operation. This upgrade reduces energy consumption by 25-30% compared to mechanical LR2 control.
Q2: What causes the LR2 control’s power limiting function to fail intermittently, and how to resolve it?
A2: Intermittent failure of power limiting is usually caused by unstable feedback or electrical interference: ① Feedback Signal Instability: Check the power feedback sensor’s wiring — loose terminals or damaged shielding can cause signal fluctuations. Replace the sensor cable with a double-shielded type (Rexroth R900023456) and secure terminals with heat-shrink tubing; ② Control Valve Contamination: The LR2 valve’s spool may stick intermittently due to fine particles. Disassemble the valve, clean the spool with ultrasonic cleaning (30 minutes, 40kHz), and reassemble with a new O-ring kit (R900912345); ③ Electrical Interference: If the pump is near high-voltage cables, install a signal filter (Rexroth VT-VRPA1-1-1X) between the amplifier and PLC to suppress noise (50/60Hz); ④ Pilot Pressure Fluctuation: Install a 0.3L accumulator in the pilot circuit to stabilize pressure (30-40 bar) during load spikes. After troubleshooting, test the power limiting function 10 times with varying loads to confirm stability.
Q3: How to integrate the pump with a hydraulic energy recovery system for regenerative braking (e.g., in mobile cranes)?
A3: Energy recovery integration leverages the pump’s bidirectional potential (when used as a motor): ① Hardware Configuration: Install a check valve (Rexroth SL 20 PA1-4X) and a high-pressure accumulator (50L, 350 bar) between the pump’s pressure port and the crane’s brake cylinder; ② Control Logic: When the crane lowers the boom (braking), the load drives the pump to rotate as a motor, charging the accumulator with high-pressure oil (via the check valve); when the boom lifts, the accumulator discharges to assist the pump, reducing the pump’s load by 40-50%; ③ Pressure Setting: Adjust the accumulator’s pre-charge pressure to 180 bar (60% of the pump’s working pressure) and set the pump’s pressure limiting value to 350 bar (10 bar above the accumulator’s maximum pressure); ④ Safety Measures: Install a pressure relief valve (420 bar) and a burst disc (450 bar) on the accumulator circuit to prevent overpressure. This system reduces fuel consumption by 15-20% in crane applications.
