ID run Motor identification run. During the identification run, the drive will identify the
characteristics of the motor for optimum motor control.
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type
widely used in inverters and IGBT supply units due to their easy controllability
and high switching frequency
INU-LSU Type of optical DDCS communication link between two converters, for
example the supply unit and the inverter unit of a drive system.
Inverter unit The part of the drive that converts DC to AC for the motor.
I/O Input/Output
ISU An IGBT supply unit; type of supply unit implemented using IGBT switching
components, used in regenerative and low-harmonic drives.
