Danieli Automation shall soon launch the high performance MV drives designed for demanding metal and mining applications. The drive has shown more than satisfactory performance in:
- Fast finishing blocks
- Flat product rolling mill stands
- Flat product large coilers
- Large fans and compressors
The system is designed aiming at reliable operations with simplified maintenance due to the easy servicing, with the state of the art control structure and user interface.
Features:
Danieli Automation MV Drives are the perfect choice as AC/DC converters and multi-drive DC Link Arrangement. The main features of it are:
- Ready-to-connect cabinet unit
- Design focused on easy maintenance and quick power module replacement (wheeled power modules allow very fast substitution without any special tool or lifting device)
- Optimum interaction with automation overriding control system
- Four-quadrant operation as standard
- High degree of efficiency
- Fully-digital vector closed-loop control, for synchronous and induction motors
- High control accuracy and dynamic response
- Extremely low line harmonics spectrum
- Simple and fast commissioning
- Simple operator control and monitoring
- Remote Teleservice as option
- Extremely reliable in operation and almost maintenance-free
- Interchangeable modules, usable on both AFE or INVERTER unit
- Long-life MV capacitor units
Technical Date:
The drive units are with option of IGCT and IGBT power switching elements forming single and double unit modules. The maximum output rating of 1400 Amps (continuous duty) makes it sufficient for any application across the metals and mining sector.
Designed with stringent standards of IEC 60146 – IEC 61800-3/4/5 – IEC60204-11 – IEC62103 – EN62271 and EU directives for Low Voltage and EMC guidelines. Type test according to EN62271-200 Short circuit withstanding and arcing due to internal fault.
Control Architecture:
The control structure is based on a powerful, state-of-the-art Danieli Automation Process Automation Controller (DA-PAC), that communicates with power part (modulator boards) with Ethercat optical fiber hi-speed link to ensure control trouble-free operation in the worst EMI environment. The control unit handles the drive system and its auxiliary system, monitoring the transformer, the converter power part and the motor, for safe operation and troubleshooting. The control system software is written in CoDeSys, a powerful IDE IEC – 61131-3 compliant, that is an industrial standard for automation and real-time fast control system. The controller could be interfaced with any overriding control system using any type of fieldbus. The powerful multi-core processing unit Process Automation Controller allows also the implementation of the logics and sequences needed for the control of the Auxiliary Systems.
The controller could be equipped with remote access facility to allow teleservicing, remote troubleshooting and system monitoring.
Operator Panels:
The drive system is equipped with two operator panels (colour touch panels), one for AFE and Inverter parametrization (OP1, located on the control unit door), while the other is for the complete drive system monitoring and it is normally located on auxiliary MCS cabinet door (OP2).
Powerful PC commissioning Tool for AFE and Inverter:
The drive control unit could be easily interfaced to a PC, using Ethernet with a simple patch cable.
Danieli Automation has developed a powerful software tool application QDrive Configuration Tool – that
allows drive parametrisation, tuning, accurate and fast signal tracing, saving-retrieving drives parameters and advanced troubleshooting.
Maintenance:
Simple and fast maintenance is a key factor for reliable equipments. The design of the power modules,realized with wheeled frames, allows a fast and easy replacement in about 30 minutes. Moreover, special tools or lifting device are not necessary for modules substitution.
Danieli Automation provides the Remote Teleservices, a flexible and effective service solution to reduce assistance costs and optimize intervention time. Danieli Automation has set up facility to allow the trouble shooting and monitoring of the MV drives working at our partners’ sites.
