Product description

Set-up:

The IAC-R valve basically consists of:

• Direct operated high-response valve (1) with control spool and sleeve in servo quality
  • Integrated digital axis controller (2) with analog and digital sensor interfaces and field bus connection (X3)

High-response valve with integrated axis controller with analog interfaces (X1, X4) and digital interface (X7)

Functional description

The IAC-R valve (Integrated Axis Controller based on high-response valves) is a digital high-response valve with integrated axis controller and the following functionalities:

• Flow control
  • Position control
  • Pressure control
  • p/Q function
  • Substitutional position/pressure or position/force control
  • NC functionality
  • The command value presetting can alternatively be specified via an analog interface (X1) or via the field bus interface (X3)
  • The actual value signals are provided via an analog interface (X1) and can additionally be read out via the field bus (X3).
  • The controller parameters are set via the field bus.
  • Separate supply voltage for bus/controller and power part (output stage) for safety reasons
  • Parameterization
  • Programming of NC functionality
  • Diagnosis
  • Comfortable data management on a PC
  • PC operating systems: Windows 2000 or Windows XP
  • Cable break sensor technology
  • Undervoltage
  • Temperature of the integrated electronics
  • Communication error
  • Watchdog
  • Ramp generator
  • Internal command value profile
  • Enable function, analog/digital
  • Error output 24 V (e.g. as switching signal to PLC/logic and additional valves), max 1.8 A
  • Actuating variable adaptation
    • Dead band compensation
    • Zero point correction
    • Valve inflection compensation
    • Friction compensation
    • direction-dependent amplification

WinHPT PC program

To implement the project planning task and to parameterize the IAC-R valves, the user may use the WinHPT commissioning software (see accessories):

The digital integrated control electronics enables the following error detection:

The following additional functions are available:
