Bonfiglioli VCB industrial series Frequency Inverters

* Discontinued series
Bonfiglioli
 

Bonfiglioli VCB inverters are designed for applications calling for speed, torque, position control of three phase asynchronous motors 132 kW rating and larger. The robust and flexible VCB series spans over a 132 to 800 kW range, covering a broad spectrum of applications, and is the ideal drive for large industrial plans and manufacturing lines. Power ratings from 355 kW to 800 kW are catered for by connecting two VCB units in parallel.

Bonfiglioli frequency inverter VCB series is convenient in operation and flexible in application.

With the VCB range, BONFIGLIOLI VECTRON introduces a powerful generation of frequency inverters. Their all-in-one features are bound to provide the right solution for your drive requirements - from simple speed variation applications up to high dynamic servo applications. You will find the right specialist partner in BONFIGLIOLI VECTRON who gained a wealth of experience accumulated from several 100,000 installed frequency inverters. Drives with BONFIGLIOLI VECTRON frequency inverters offer solutions of rational use of energy and materials in smallest possible physical size - it is a way to bionic drives.
Bonfiglioli frequency inverter VCB series is convenient in operation and flexible in application.
- Smooth acceleration with torque control.
- Excellent revolving at high and very low speeds.
- Pretentious positioning even with full load torque at zero speed.
- Highly accurate synchronous operation for multi-motor drives and electronic gears.
- Highdynamic current and torque limiting for proper operation under fast load shocks.
- Sweep function with periodical speed reference profiles.

Basic functions.

Depending on the requirements you have to incorporate various features in your drives. The VCB range of frequency inverters offers you a selection of basic functions which can be activated time and/or event related.
- Application functions : Depending on the requirements you have to incorporate various features in your drives. The VCB range of frequency inverters offers you a selection of basic functions which can be activated time and/or event related.
- Adaptation for analogue inputs and outputs for range adjustment to peripheral control elements.
- Customer’s own functions can be implemented on request. Consequently, elimination of peripheral components is possible.
- Unlimited interlinking of function blocks: The properties of the VCB range can be flexibly adapted to any given drive task thanks to their freely programmable functions.
- Four different data sets if the operating modes change.
- Torque boost enables your drive also for high starting torque.
- Synchronisation to a rotating motor enables starting at any operation point.
- Controlled braking: If you need very fast shut-down without mains unit or brake unit, you can use the voltage control and the motor chopper.
- Motor potentiometer function if you wish to set the speed through a contact input.
- Technology controller: If you like to carry out for example pressure, volume flow or speed regulation with the integrated PI controller.
