R901441904 Rexroth DIGITAL AXIS CONTROL VT-HMC-2-1X/M-0-00/00

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:

– incremental or absolute (SSI, Endat2.2)

– analog ± 10 V and 4 to 20 mA CE mark according to EMC Directive 2004/108/EC
 

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.
