Danieli Automation LV QDrive, modular design and sturdy construction, internal arcing proof, to better meet customer’s requirement.

Danieli Automation LV Qdrives are designed for demanding metals rolling mill applications, with Field Oriented Control (FOC) for synchronous and induction motors, developed with focus on high flexibility, operability and maintenance. 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 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 drive system is equipped with a dedicated operator panel (colour touch panels) for Inverter parametrisation (OP1, located on the control unit door). Through the panel it is possible to perform extensive drives units and systems components parametrisation, monitoring, servicing and troubleshooting; tracing of the internal control signals it is also possible without using any additional tool or pc. 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. The controller could be equipped with remote access facility to allow teleservicing, remote troubleshooting and system monitoring.

HIGHLIGHTS

  • Very cost effective solution.
  • Up to 4000 A @ 690Vac as rated inverter current.
  • High performance due to closed loop field oriented control (FOC) for induction & synchronous motors (with separate exciters)
  • Integrated output reactor (30uH) allows easy paralleling and allows less space & wiring required in the
  • cabinets.
  • Modular design and easily withdrawable wheeled modules make it a friendly solution for maintenance technicians.
  • Minimized spare parts number.
  • The DA modular inverters could be advantageously combined with DA dc link AC/DC converters (capacity
  • up to 5000 A dc) that according to applications could be fully regenerative (AFE + F3E), partially regenerative (DFE + F3E) or unidirectional (DFE).
  • Powerful integrated PLC functions in drive control logic for drive system protections handling & maximum flexibility and easy integration with overriding control system ( Level 1 PLC).
  • Advanced maintenance & signal tracing functionalities with PC configuration program.
