The Bosch Rexroth VT-HPC-1-1X/M-0-00/00 (R901413449) is a sophisticated hydraulic pump control module designed specifically for use with the A..HS type axial piston pump. This module is engineered to manage swivel angle, pressure control, and torque limitation functions, ensuring precise operation in various applications. It features digital control electronics that simplify the commissioning process through application-specific functionality and allows for easy parameterization via standard Ethernet connections. The capability for backup and restore operations via an SD card enhances its user-friendliness.
With its installation on a DIN rail, this pump control module integrates seamlessly into existing systems. It supports multiple communication protocols including Sercos, PROFINET RT, EtherCAT, EtherNET/IP, and POWERLINK, in addition to analog connectivity options. The unit conforms to CE standards for electromagnetic compatibility within the EU and operates on a supply voltage of 24 VDC. Its modular design is both compact and lightweight.
The VT-HPC-1-1X/M-0-00/00 provides a variety of controller functionalities such as pressure control, swivel angle/flow control, torque limitation, and optional speed-variable function integration. It also offers diverse operating modes like pressure/swivel angle control and pressure/flow control. Command value presetting can be achieved through bus interfaces or analog interfaces or by using an internal PLC program.
Comprehensive monitoring functions are integrated into the digital controls for error detection including undervoltage issues, communication errors, sensor input cable breaks, short-circuit monitoring for outputs, and temperature monitoring of the electronics.
For project planning and parameterization tasks as well as commissioning and diagnostics of this hydraulic pump controller module Bosch Rexroth's IndraWorks PC software can be utilized which requires a PC operating system of at least Windows XP.
Lastly, it includes a slot for an SD memory card which enables saving parameter data among other information and allows updates to be made easily provided that the SD card is formatted to FAT with up to 32 Gbyte capacity.

Digital control electronics for the axial piston pump A4VS with HS5 control from size 40 to size 1000 Bus connection (slave)/Service interface (TCP/IP) switchable by parameters (Sercos, EtherNet/IP, PROFINET RT, EtherCAT, Powerlink, PROFIBUS DP) Pressure and swivel angle controller Parameterizable torque limitation Optional: Speed-variable function Leakage compensation Master/slave capability Mooring capability CE mark according to EMC Directive 2004/108/EC Optional: PLC functionality according to IEC 61131-3
Functional description using the A4VS axial piston pump with HS5 control as an example
The swivel angle and pressure control as well as the torque limitation of the A4VS… variable displacement pump are effected by an electrically controlled proportional valve (1). Via the actuating piston (2) of the pump, this valve determines the position of the swash plate (3).
The position of the swash plate is determined by a swivel angle sensor (4); the actual pressure value is recorded by a pressure transducer.
The actual torque value is calculated from the product of the actual pressure value and the actual swivel angle value. The controller software ensures by means of a minimum value generator that the controller corresponding to the working point is always active.
The sectional drawing shows the A4VS… variable displacement pump with HS5 control; the proportional valve (1) is controlled using the VT-HPC control electronics.
Notice for the HS5 control:
With de-energized proportional valve and pump with clockwise rotation and if the set pressure is available, the pump swivels to swivel angle α = 0 (A4VSO design) or α = –100% (A4VSG design).
Functional description of the control electronics
Description
The VT-HPC (Hydraulic Pump Control) is a digital control system with integrated controller, optionally with programming according to IEC 61131. The internal PLC functionality is activated by plugging the SD card SD-HPC-PLC. It is not included in the VT-HPC scope of delivery and must be ordered separately.
The following controller functionalities are available:
Pressure control Swivel angle/flow control Torque limitation Optional: Speed-variable function (n function)
This enables, amongst others, the following operating modes:
Pressure/swivel angle control Pressure/flow control
Command value presetting is done via the bus interfaces (XF20/XF21 or XF30), via the analog interface (XG20) or, alternatively, via an internal PLC program.
The feedback information of the actual value signals to the superior control system is provided optionally either via the bus interfaces (XF20/XF21 or XF30) or the analog/digital interface (XG20).
The controller parameters are set via one of the two Ethernet interfaces (XF20/XF21) (integrated switch functionality)
Monitoring
The digital control electronics enable comprehensive monitoring functions/error detection including:
Undervoltage Communication error Cable break for analog sensor inputs (4 ... 20 mA) Short-circuit monitoring for analog/digital outputs Temperature of the integrated electronicsIndraWorks PC program
To implement the project planning task and to parameterize the VT-HPC, the user may use the IndraWorks DS operation tool. For the use of the PLC function, IndraWorks MLD is necessary:
Project planning Parameterization Commissioning Diagnosis Comfortable management of all data on a PC Requirement: PC operating system at least Windows 7
Slot for one SD memory card
The following data may be saved:
Parameter data Any other data Update of the speed-variable function (see Accessories)
Only SD and SDHC memory cards up to a size of 4 Gbyte with FAT32 formatting are supported. The card must already be inserted when the device is switched on, otherwise it will not be detected. It is recommended to use the Rexroth memory card (see Accessories).
