The Bosch Rexroth VT-HMC-2-1X/M-0-00/00 (R901441904) is a sophisticated digital axis controller designed for precise hydraulic motion control across two axes. It offers versatile functionality, including position, pressure, force, and velocity control, with the ability to switch between position-force or pressure-volume (pQ) control. This module is engineered to streamline commissioning through its application-specific features and can be parameterized using standard Ethernet connections. Data backup and restoration are simplified with an SD card slot. The VT-HMC-2-1X/M-0-00/00 facilitates various operating modes such as valve direct control, drive-controlled position control, drive-controlled positioning, and positioning block operation. Command value presetting can be managed via multiple bus interfaces or analog interfaces, or through an internal PLC program. The device supports independent axis operation or synchronized control for coordinated movements. For communication with higher-level systems, Bosch Rexroth provides function blocks that can be accessed online. The controller parameters are adjustable via dual Ethernet interfaces with integrated switch functionality. Comprehensive monitoring functions are embedded within the digital electronics, ensuring error detection for issues like undervoltage, communication errors, sensor input cable breaks, short-circuit monitoring for outputs, microcontroller watchdog activity, electronics temperature checks, and overcurrent conditions. The VT-HMC-2-1X/M-0-00/00 is compatible with IndraWorks engineering tools for project planning and parameterization tasks. This includes PLC program preparation and commissioning diagnostics. The module accepts SD memory cards up to 2GB using SPI bus connection (excluding SDHC cards), which must be inserted upon device startup. This controller aligns with the CE mark according to the EMC Directive EC and is part of component series X. It offers a range of communication protocols such as Sercos, PROFINET RT, EtherCAT, EtherNET/IP, POWERLINK with optional PROFIBUS support alongside analog connectivity options. It's tailored to meet the demands of BEST IN CLASS hydraulic controllers while ensuring seamless integration into various hydraulic system applications.

HYDRAULIC MOTION CONTROL VT-HMC-2-1X/M-0-00/00

Hydraulic motion control for two axes, functional scope: Position, pressure, force, velocity, alternating control (position/force or p/Q)

Digital axis controller for electro-hydraulic axes. Reduction of commissioning thanks to application-specific functionality. Parameterizable via standard Ethernet; backup/restore via SD card.

Unpacked Weight: 0.635 kg

PLC functionality according to IEC 61131-3 BEST IN CLASS hydraulic controllers Bus connection (slave)/Service interface (TCP/IP) switchable by parameters (Sercos, EtherNet IP, PROFINET RT, EtherCAT, PROFIBUS, Powerlink) Measurement system of hydraulic axes:

Description

The VT-HMC (Hydraulic Motion Controller) is a digital controller with integrated axis controller and programming functionality according to IEC 61131-3.

The following controller functionalities are available:

Position control Force control Pressure control Substitutional control (position/pressure and force) Velocity control

This enables, amongst others, the following operating modes:

Valve direct control Drive-controlled position control Drive-controlled positioning Positioning block operation

Command value presetting is done via the bus interfaces (XF20/XF21 or XF30), via the analog interface (XG20/XG21) or, alternatively, via an internal PLC program. Axis variant 2 enables independent operation or synchronization control (in preparation) of the axes.

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/XG21). For communication with the superior control system, Bosch Rexroth offers function blocks online under www.boschrexroth.com/HMC.

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) and digital position measurement system Short-circuit monitoring for analog/digital outputs Monitoring of the microcontroller (watchdog) Temperature of the integrated electronics Over-current of 24 V sensor voltage and digital outputs

IndraWorks MLD or DS PC program

To implement the project planning task and to parameterize the VT-HMC, the user may use the IndraWorks engineering tool (see accessories):

Project planning Parameterization Preparation of the PLC program (IndraWorks MLD requirement) Commissioning Diagnosis Comfortable management of all data on a PC Prerequisite: PC operating system Windows 7

Slot for one SD memory card

The following data may be saved:

PLC program Any other data

Only SD memory cards with SPI bus connection are supported (no SDHC memory cards).

The card must already be inserted when the device is switched on, otherwise it will not be detected. Cards that are not FAT-formatted are formatted automatically (FAT 32).

The maximum capacity of the supported memory cards is 4 GB.

Maintenance instructions:

The devices have been tested in the plant and are supplied with default settings. Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to re-transfer the corresponding user parameters.

Notes:

The supply voltage must be permanently connected; otherwise bus communication is not possible. Connectors may only be plugged or unplugged in the de-energized condition. In particularly EMC-sensitive environments, additional measures must be taken (depending on the application, e.g. shielding, filtration) 2) Wiring information Maximum possible clearance between signal and load lines. Do not lead signal lines through magnetic fields. If possible, install signal lines without intermediate terminals. Do not install signal lines in parallel to the load lines. Connect cable shields (see operating instructions) For digital inputs and outputs, the max. recommended cable length is 30 m. Only use shielded lines for sensors (incremental, absolute or analog). Max. recommended cable length: 50 m; also observe the sensor manufacturers’ information. The signals of the connector XG20/XG21 are not galvanically separated. A potential reference therefore always has to be established when connecting external devices. For additional notices, see IndraWorks online help and operating instructions 30239-B. The upper and lower ventilation slots must not be concealed by adjacent devices in order to provide for sufficient cooling. Observe the installation information in the operating instructions 30239-B.

1) The documentation is available as online help in IndraWorks.

2) To use the HMC for household or small business applications, special precautions, such as installation of a shielded housing and appropriately approved filter systems, are required to fulfill the emission requirements according to EN61000-6-3.
