Advantages and features of Rexroth control unit

‌High-efficiency design‌

Hydraulic pumps and motors have high power density, compact size but strong output power, suitable for heavy machinery and energy equipment.

The servo system adopts high-precision electromagnetic design and dynamic response algorithm, supports fast start and stop and reverse movement, and meets the needs of high-precision industrial scenarios.

‌Precise control characteristics‌

The proportional amplifier module achieves high-precision signal control through differential input (±10V) and current input (4-20mA), driving the proportional valve solenoid to perform precise actions.

The control software integrates intelligent algorithms, supports characteristic curve correction and ramp time adjustment, and optimizes dynamic response and stability.

‌Modularity and flexibility‌

Supports multi-device linkage control (such as the brake unit can synchronize up to three devices), and adapts to diverse working conditions through stepless variable adjustment.

The hydraulic system supports customized configuration, and can be combined with multi-pump structure to improve space utilization.

‌Multiple protection mechanisms‌

The brake unit has built-in overvoltage, overcurrent, short circuit and resistor overheating protection to ensure the stability of the inverter bus voltage and safe operation under high load.

The driver is equipped with soft start, fault detection (such as overvoltage, undervoltage) and IP65 protection level to adapt to harsh industrial environments.

Precautions for use

‌Maintenance requirements‌

The quality and sealing of the hydraulic oil should be checked regularly to avoid leakage that may lead to performance degradation or environmental pollution.

The servo system needs to calibrate the control parameters and clean the heat dissipation channel to prevent overheating from affecting stability.

‌Operation mode adaptability‌

Electromagnetic operation is suitable for automation control scenarios, while hydraulic operation is more suitable for harsh environments such as high temperature and high pressure.

The cable length between the brake unit and the inverter should be controlled within 5 meters to avoid signal attenuation.

‌Installation and commissioning specifications‌

When installing the proportional valve or amplifier module, follow the electromagnetic compatibility requirements to reduce external interference.

During the commissioning phase, the action voltage should be gradually adjusted (600-785V range, step size 0.01V) to ensure matching with the load.

‌Environmental adaptability‌

The hydraulic system needs to preheat the oil in a low temperature environment to avoid viscosity changes affecting the response speed.

In high dust environments, the driver protection needs to be strengthened (such as IP65 level) and the heat dissipation vents need to be cleaned regularly.
