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, X7)
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:
- Substitutional position/pressure or position/force control
- 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
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):
- Programming of NC functionality
- Comfortable data management on a PC
- PC operating systems: Windows 2000 or Windows XP
The digital integrated control electronics enables the following error detection:
- Cable break sensor technology
- Temperature of the integrated electronics
The following additional functions are available:
- 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
- Valve inflection compensation
- direction-dependent amplification
