SUMMARY: Digital controller HMC 1X
Quantity in stock: 6
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.
