5.1 Drive Family Description
GenIV is the fourth generation of forced air-cooled medium voltage, voltage source inverter
drives offered in the patented Robicon Perfect Harmony topology. GenIV differentiates itself
from prior generations in that:
● The 200 - 2250 Hp, 4160 V frame uses a single enclosure (no shipping splits)
● At its inception, the 200 - 1100 Hp, 4160 V drive is the smallest footprint MV AC drive in
the world
● Nine Cell configuration for 4160 V output (750 V cell input, and O-M techniques)
● The 300 - 3500 Hp, 6600 V frame consists of a transformer enclosure mated to a cell
enclosure without shipping splits (2000 Hp or below) or 1 shipping split (above 200 Hp).
● The 600-6000 Hp, 10000 V frame consists of a transformer enclosure mated to a cell
enclosure with 1 shipping split.
● Transformer and cell sections have independent intake air cooling paths
● NXGII control with integral I/O system and Eagle software
● Power cell connections are made with blind mate power plugs and locking latches (no
fasteners)
The GenIV is a series of adjustable speed AC motor drives presently available in 4160 V,
6600 V and 10000 V and 6600 V outputs, and loads ranging from 200 - 6000 Hp. Six power
cell amperage types are available: 40, 70, 100, and 140, 200 and 260. Drives in this product
series provide an efficient, cost effective, and reliable method of adjusting the speed of an
AC motor. The core unit contains a wide range of expandable features, enabling it to meet
the demands of many types of industrial applications.
Siemens GenIV (also known as MicroHarmony) may be purchased in one of three
configurations.
