The Beckhoff Hydraulic Library

The Beckhoff Hydraulic Library

Advantages

  • software library integrated into PLC
  • replaces external controllers
  • suitable for hydraulic components of all manufacturers
  • supports different concepts and applications
  • any number of axes, only dependent on CPU

Suitable for

  • valve-controlled hydraulics
  • pump-controlled hydraulics (hybrid axes)
  • control of servo pumps
  • servo-electric axes with the functional scope of the hydraulic library
  • parallel operation with TwinCAT NC PTP/NC I/CNC (TX1250, TX1260, TX1270 or TC1250,TC1260, TC1270)
  • complex or interpolating movements in interaction with TwinCAT NC I/CNC (TX1260, TX1270 or TC1260, TC1270)
  • support of various axis couplings (synchronous, cam plates)

Functions

  • programming via certified PLCopen motion blocks
  • set value generators especially for hydraulic applications
  • coupling of the set value generators to NC PTP/NC I/CNC possible
  • free profile design through connection of customer-specific set value generators
  • support of non-linear gears
  • multiple-segmented movements (blending)
  • support of all necessary interfaces via Beckhoff I/O system
  • support of all common fieldbus systems
  • all process values in physical units, determination of force true to surface
  • support of standardised and application-specific controllers for position, force/pressure
  • bumpless transfer of force and position control
  • automatic identification of valve characteristics and axis properties
  • linearisation of characteristic curves
  • maintenance and commissioning tool for
    • axis parameterisation
    • valve parameterisation incl. characteristic curves
    • controller parameterisation
    • triggering of test commands
    • display of actual values
