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 (X4/X7) or digital (X7) sensor interface
PROFIBUS interface (X3) with functionality according to DP/V1 and clock synchronization according to DP/V2

Functional description

The IAC-R valve is a digital high-response valve with integrated axis controller and the following functionalities:

Position control
DSC functionality
analog (X4/X7) or digital (X7) sensor interface
clock-synchronized command value presetting according to PROFIdrive profile V4.0
Telegram 5 or 105
The controller parameters are set via the PROFIdrive parameter protocol
Separate supply voltage for bus/controller and power part (output stage) for safety reasons

The digital integrated control electronics enables the following error detection:

Cable break sensor technology
Undervoltage
Temperature of the integrated electronics
Communication error
Watchdog
Synchronous monitoring

The following additional functions are available:

Error output 24 V or control of an isolator valve
Actuating variable adaptation
Dead band compensation
Zero point correction
Valve inflection compensation
Friction compensation
direction-dependent amplification
PIDT1 controller
State controller
Automatic/semi-automatic drive measurement for easy controller optimization

 

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):
