Structure and Method of working
The units meet with the European (CE)-,
UL- and c-UL- standards.

The current rectifiers of the series KIMOREG D installed for the controlling of motors are designed that they can be installed with the pertinent control devices in a standard enclosure.
The rectifiers are designed for connection to a three- phase mains in a voltage range form 110 V AC to 500 V AC. They supply controlled DC-output voltages or-currents for anchor and field for externally actuated DC-shunt-motors as well as for permanent magnet actuated DC motors.

The units can be supplied in 1 quadrant as well as in 4-quadrant models.

A 1-quadrant unit consists of a fully controlled rotary current thyristor bridge (B6)C with full protection against overload and excessive voltage as well as the relevang electronic regulating circuits.

A 4-quadrant unit consists of two fully controlled rotary current thyristor bridges (B6)A (B6)C with modern electronics for the control of rpm and rotary moment for drive and braking in both rotary directions.

All rectiviers are equipped with an integrated field regulator, this makes a regulated field low power operation possible.

The mains connection is independent of rotary field. An in-built two-line alpha-numeric LCD-dixplay shows the rectifier-relvant information or on the occurence of a fault its cause immediately. The LCD-display represents moreover a valuable diagnostic and since it has access to all alarms, inputs and outputs as well as the main software blocks of the regulator. The LED-display under the font cover-hood show at any given time the drive status and gives information regarding the state of the most important inputs and outputs.

Der Systemantrieb
Mit den zahlreichen Softwarefunktionen, die dieser Systemantrieb bietet, können unter anderem komplexe Wickelaufgaben gelöst und Verfahrensregler (PID-Regler) ohne aufwendige Zusatzelektronik nachgebildet werden.

Die vielfältigen Möglichkeiten des KIMOREG D erlauben den Einsatz des digitalen Stromrichters für komplexe Antriebs- und Regelungsaufgaben ebenso wie für einfache Drehzahlregelungen.

Standard software funktion blocks

  • Automatic on/off switching sequence
  • Patented blocking period extension for 4Q-model
  • PID-Technology regulator
  • Multi-lingual Display
  • Self-optimisation
  • Tip-and crawl nominal values
  • 4 different field regulation types
  • in- and outputs are freely configurated
  • Angle calculator with direct or indirect draft regulator
System Integration
The three serial interseciton points allow a monitoring and guiding of the instruments via PC-supported lead systems, digital operator systems or SPS-systems or also via the combination of all three.

Higher voltage - less current
The patented blocking period extension allows the operation also of 4-quadrant -rectifiers with an anchor voltage of 460 V, as is usual in the case of 2-quadrant-rectifiers (in the case of power connection of 3 x 400 V). This results in a reduction of powe rused with the same output which entails a reduction in costs for the user with regard to the wiring, the switch-instruments and the rectifier.

Typical applications

  • Main drive for arcing and rotation printing machines
  • Portable and lifting drive in the lifting appliance industry for cranes, shelf-conveying-appliances, lifts etc.
  • Lift and cable-way operation
  • Needling machines for the textile Industry
  • Rolling mill drives
  • Shearing drives in the steel industry
  • Paper machines
  • Winding drives for foil, paper, wire etc.
  • Horizontal cutters
  • Profiling machines
  • Loading machines for Motor-turbines-or transmission testing stands

IPS software parametering made easy
The software IPS (Instrument Programming Soft-ware) makes to possible to program and configurate the drive from any PC. The adjustment of the dircuit regulation follows independently (self-adjusting).

Clear Programming
Simple putting into operation

A 32 character comprehensive alphanumeric display shows the user all diagnostic and operation parameters as well as comprehensive error and status reports in clear text. The clearly designed software leads the user through various menu surfaces quickly to the parameters relevant for him. The operating field is available in German, English, French, Italian and Spanish.The digital rectifier KIMOREG D offers the possibility of stroing all parameters through a standardised serial intersection point on a PC. For the user this has the advantage that he can document and store all input drive parameters on a diskette. In case of need these paramters can be called up, compared or loaded in anew rectifier.
