The Bosch Rexroth VT 5041-3X/V13D (R901263600) is an advanced analog control electronics card designed specifically for SYDFE system applications, providing precise control over pressure and swivel angle. This eurocard format insertion card includes a command value input for both pressure and swivel angle, with the option of a power limitation function. It features a pressure transducer to measure actual pressure values and a position transducer to gauge the swivel angle, ensuring accurate monitoring and feedback for system adjustments. The card processes actual values through amplifiers, which then compare them with command inputs. A minimum value generator ensures that only the relevant controller is activated based on the operating point requested. The optional power limitation feature can be set internally or externally to manage the swivel angle command value, preventing system overloads. For valve control, the VT 5041-3X/V13D employs an inductive position transducer coupled with an oscillator-demodulator switch to determine the valve spool’s actual position. This information is processed by a dedicated controller that manages the proportional solenoid of the valve through a self-timing power output stage. In terms of diagnostics, this model includes a fault message output that indicates errors through voltage signals and LED flashes. It can be configured to de-energize in response to various faults such as internal voltage supply issues or exceeded measurement ranges. The Bosch Rexroth VT 5041-3X/V13D offers additional features like reverse polarity protection, switchable pressure inputs, LED indicators for operational status, and optional display instruments for real-time swivel angle monitoring. Its design supports multiple hydraulic volumes and includes circuitry for pressure controllers that can be adjusted or toggled according to system needs.

Version without power limitation with swivel angle display - Modified function / customer-specific

Unpacked Weight: 0.2115 kg

Implementation of the electronic functions of the SYDFE1 control; pressure and swivel angle control; optional power limitation Pressure controller circuitry can be adjusted and switched to two existing hydraulic fluid volumes (actuators plus lines) Differential amplifier inputs Controller for valve spool position Minimum value generator for pressure and swivel angle controller Self-timing output stage Pressure-dependent leakage compensation (can be switched off) Reverse polarity protection for voltage supply Switchable actual pressure value input (current, voltage, range) 6 LED displays on the front plate for the operating state Display instrument on the front plate for actual swivel angle value (optional) Power limitation with internal or external command value presetting (optional)

The analog control electronics VT5041-3X/... is designed as insertion card in euro format. It is provided with a command value input each for pressure and swivel angle [1] as a standard (optional power limitation). The actual pressure value is measured with a pressure transducer. The position transducer at the pump measures the actual swivel angle value. The measured actual values are processed in amplifier [2] and [3] and compared with the provided command values. The minimum value generator [4] controls that only controller [6] or [10] which is allocated to the requested operating point is automatically activated. The output signal of the minimum value generator [4] becomes the command value for the valve control loop. The optionally available power limitation is automatically activated by the provision of a suitable command value. The power command value can be provided internally or externally. If necessary, it limits the swivel angle command value by means of a minimum value generator [5]. The resulting swivel angle command value can be measured at socket 7.

The actual valve value (position of the valve spool) is measured with an inductive position transducer. An oscillator/demodulator switch [7] enhances the signal. The control deviation is generated and processed in the controller for the valve spool position [8]. The output signal of the valve controller [8] forms the command value for the self-timing power output stage [9] which controls the proportional solenoid of the valve.

The control electronics is equipped with a fault message output where a voltage of 0 V is applied in an error case (= low-active). At the same time, the "Err." LED flashes. Depending on the jumper J1 configuration, the valve output stage can be de-energized in case of an error message.

Causes for fault messages:

Error in the internal voltage supply The actual pressure value is greater than the admissible system pressure (socket 2: pact > 11.5 V) No enable signal at port 26c Cable break or range of the swivel angle return exceeded Cable break or range of the valve spool return exceeded Cable break "pressure transducer" (for adjustments 4...20 mA, 0.5...5 V and 1...10 V) Control error (control difference x controller amplification) is greater than 4 V (40 %) for more than 1 second

In an error case, the electronics can be configured so that the output stage is de-energized and the valve spool is pressed to its mechanical end position. This causes the pump to swivel back. The error can only be acknowledged by resetting the enable signal.
