All the Electronic Instrumentation necessary to command and control mono or multi-axial Test Benches is developed internally. We pay particular attention to the presentation of the various parameters on the monitor, since it is very important, particularly in those Benches devoted to Experimentation and Research.
Our Workstations allow to:
Command the Hydraulic Power Unit and any Substation. The flow and the feeding pressure as well as the correct functionality of the major internal components (filter, levels, etc.) are electronically controlled.
Manage the entire Test Bench operation, choosing among the various options for control, command, alarm and display
Our load generation systems are implemented in closed loop, that is, with active control of the loads.
All electrical/electronic connections with the outside are implemented with safety connectors and/or sheathed cables and Palazzoli connector for power supply from the electrical panel.
Single channel Workstation ‐ type A
This Electronic Instrumentation is designed to command and control one mono axial Test Bench. Its software runs in Windows environment and implements:
the generation of standard test sequences (e.g. sinusoidal, triangular, square, ramp). Others can be defined of various type, being programmable either through the GUI, or imported from external file
reading, storing, and processing of the signals, with dynamically costumizable plots (y/t, x/y, etc.)
the start, stop, and freeze of the Test
per-channel measurement of the peak values
the control of alarms set on critical signals, with customizable warn thresholds
The software is also designed to perform static, dynamic, block, and spectrum tests, with guided settings available to the operator.

Multi channel Workstation ‐ type B
Modular Workstation, whose architecture can be extended in function of the specific application requirements. The basic module of WKS-B is a self-contained processing unit, specialized in the control of a servo-system of a Test Bench. The interconnection of multiple modules in a Rack is implemented via Ethernet Switch and the overall control is delegated to a control pulpit with Main Computer.
The WMC-B-n Workstations can therefore be connected in cascade to compose multiaxial systems of increasing complexity, in which the first WKS-B acts as the master for all the others.

Control Software
We implement all the software needed to control the Workstation through a user friendly interface, in function of the number of channels to manage, the testing requirements, and the specific characteristics of the Test Bench.
A good visualization allows to be interactive with the Test Bench and to be able to make timely and safe interventions, both during the setting and during critical tests.
As shown below, we implement different display modes for multi-axial and mono-axial Benches.
