Active Extended Diagnostic

Everything is under control
Are you loosing production hours and days checking around the machine for which connection wire, PLC card, push-button or fuse are faulty?…


Forget these kind of problems with PARMIGIANI's
i-Diagnostic system for immediate fault detection.
The i-Diagnostic is a revolutionary diagnostic system that supervises all the main functions of the machine, with an easy to use and intuitive control panel interface.
From the touch-screen you can control almost all electrical connections around the machine; all PLC modules; all micro-switches (You can check also if they are engaged /energized or not) and more....i-Diagnostic: a revolution in customer support.

Instantaneous fault detection instead of troubleshooting 
Detailed information on type and location of the fault

The PPS is the most advanced parallelism system available on the market today.
The rolls parallelism in a plate bending machine is a key factor for production accuracy.
The capability to maintain precision over years of performance is also another critical point. For this reason we employ the best of today's available technology with digital control systems and hydraulic flow control via proportional valves.
We have designed a system resistant to wear that will give you years and years of trouble free performance, keeping the machine positioning precision just like your first day of operation!
The top and bottoms rolls parallelism is fully controlled by a digital “high speed” FIELD BUS system.
The package includes a set of hydraulic proportional valves with high performance digital control cards, matching  the high speed of the FIELD BUS system.
This digital technology (the loop control is 20 times faster than PLC-based electronic controls) joined with the hydraulic proportional valves, provides a parallelism precision of about 0.1 mm.

Plug and play technology

Do It by yourself
"Assemble and plug in – that’s all!"
Quick and simple plug connections replace elaborate wiring.
• Avoids wiring errors
• Shortens start-up time
• Quick swapping of cables

The wiring of the machine is achieved by Plug and Play  connectors and digital distributors.
The cabling system with connectors is more reliable over time, resistant to environmental contamination and vibration and allows for quick and easy maintenance.
 
With our FACILE® Plug and Play system you can change a wiring connection (to the hydraulic valves or the encoders or potentiometers, to a micro-switch etc…)  with pin plug connector, without unscrewing any electrical wire.
Same procedure for all PLC modules! Without the need of a skilled electrician!
 
With the purpose of increasing your independence from third parties all software are loaded in static memory cards, (like the ones used in digital video cameras) and not in volatile Eprom!  This means that you will almost never lose the software, even when you need to change the PLC unit.
Our plug-play system is a military approved technology!

Advanced Hydraulic System 

Infinitely variable adjusting speeds
Infinitely variable bending pressure

The hydraulic system is the operative core of your VBH: it runs everything from the bending rolls drive to the bending rolls movement, tilting and all other machine attachments.
 
This is why we invested a lot in research and development to give you a smooth, precise and highly responsive system.
 
Through digital controls the system is managed by dedicated hydraulic proportional valves (pressure and flow) that allows you to select the most convenient speed during each production step (vs. other brands machines that give you only one or two selectable speeds) and the maximum central lower roll pinching force in order to adapt it  to the characteristics of the plate being worked.
 
The possibility to select low pressures for thin plates widely extends the range of the machine.
 
With infinitely variable pressure and speed adjustment the operator will have full control of the process in any bending situation.
