5. Operating instructions
Basically the electronics performs the task of
converting a command signal into a proportional
control value via the connected valve with the
highest possible dynamic. For these purposes the
input value will be electronically compared with
the feedback of the process value (i.e. the spool
position) within the module. The signal difference
feeds a position controller, that in turn provides via
a power amplifier stage the required current for the
solenoids of the valve.
5.1. Operating software program
ProPxD parameterizing software:
The ProPxD software permits comfortable param-
eter setting for the module electronics. Via the
clearly arranged entry mask the parameters can be
noticed and modified. Storage of complete param-
eter sets to floppy or hard disk is possible as well
as printout or record as a text file for further docu-
mentation. Stored parameter sets may be loaded
anytime and transmitted to the module electronics
in the same manner as the basic parameters which
are available for all usable valve series. Inside the
electronics a nonvolatile memory stores the data
with the option for recalling or modification. The connected valve may not operated before
loading an appropriate parameter set from
the PC into the module electronics!
