R911305274+R911312231 Control Unit & Firmware High Precision New Original

Product Description:

Rexroth's control units and hardware are known for their high performance and reliability in the field of industrial automation. Its core advantages and usage precautions are as follows:

1. Core advantages and features

Modular design, strong compatibility

The control unit adopts an open architecture and supports a variety of industrial bus protocols (such as CAN FD, Ethernet, etc.), which is easy to integrate with other devices.

The hardware interface complies with international standards such as ISO 4401 and has strong adaptability. For example, the directional control valve can be directly installed through the base plate.

High precision and stability

The servo system combines high-rigidity servo motors and intelligent drivers, and realizes complex algorithm control through DSP chips, with fast response speed and positioning accuracy up to micron level.

The pressure reducing valve (such as the ZDR series) adopts a sandwich plate design, precise pressure control, supports secondary circuit pressure limitation, and high stability.

Durability and environmental adaptability

The guide rail products (such as the RSR series) increase the contact area through the roller structure, with a rated load of up to 200kN, and are corrosion-free for long-term use in salt spray environments.
Proportional directional valves (such as the 4WRZE series) use low-friction slide valves and hidden manual override designs, which can be operated in case of electronic failures.

‌Intelligence and safety ‌

The controller integrates hardware security modules (HSM) and Lockstep processing technology to provide multiple protections such as overvoltage and overcurrent, and has passed functional safety certification.

Supports IoT applications, such as adding new functions through NodeRED to adapt to future automation upgrade needs.

2. Precautions for use

‌Hardware installation and maintenance ‌

PLC wiring needs to be operated gently to avoid violent plugging and unplugging of input/output interfaces; address coding must be strictly corresponding (such as input 0.0–0.7, output 1.0–1.7).

The guide rails need to be lubricated regularly, and the lubrication cycle can be extended to twice the industry average, but temperature fluctuations need to be monitored (such as the temperature difference in die-casting scenarios should be controlled within ±2°C).

‌Fault prevention ‌

Common overload or short-circuit faults in tightening controllers require regular inspection of power supply stability and grounding conditions.
When the system pressure is insufficient, check the unloading valve function first instead of directly replacing the pilot valve.

‌Selection and Optimization‌

Select the controller model according to the load requirements (such as the new model that supports CAN FD) to avoid cost waste caused by functional redundancy.
The directional valve flow must match the equipment requirements (such as 4WE6D supports up to 32GPM) to prevent action delays caused by insufficient flow.
