Description
Insulated gate bipolar transistor; a voltage-controlled semiconductor type
widely used in drives due to their easy controllability and high switching
frequency
IGBT type rectifier and related components enclosed inside a metal frame or
enclosure. Intended for cabinet installation.
IGBT supply module(s) under control of one control board, and related
components such as LCL filters, main contactor, fuses etc. See
module.
In cabinet-installed drives, ICU is the incoming unit (cubicle) which contains
main circuit breaker and the busbars for the input power cable.
DC link
Inverter unit
Converts direct current and voltage to alternating current and voltage.
Inverter bridge, related components and drive DC link capacitors enclosed
inside a metal frame or enclosure. Intended for cabinet installation.
The part of the Drive that converts DC to AC for the motor. Consists of one or
more inverter modules and their auxiliary components.
The inverter unit is also capable of feeding energy from a decelerating motor
into the DC link.
IGBT supply unit
Input/Output
Inductor-capacitor-inductor filter for attenuating harmonics
Simplified version of a low power multidrive (400V and 500V) with less options
and configurations. Includes only max 980A DSU, max 810A IGBT supply units
and R1i-R7i inverter units.
Drive for controlling several motors which are typically coupled to the same
machinery. Includes one supply unit, and one or several inverter units.
In the control program, user-adjustable operation instruction to the drive, or
signal measured or calculated by the drive
Optional DDCS communication module
Converts alternating current and voltage to direct current and voltage.
Drive for controlling one motor
