AMC The application and motor controller (AMC) is a digital
signal processor and the heart of the drive
control system.
AMCOS Application and Motor Controller Operating System
ANSI American National Standards Institute
AO Analog Output
APU Auxiliary Pump Unit
ARU Active Rectifier Unit
The ARU rectifies the voltage of the supply network to the
DC voltage and maintains the DC-link voltage at a
constant level irrespective of changes in the supply
network. The unit is designed as a self-commutated, 3-
level voltage source inverter consisting of three identical
phase modules. The unit allows regenerative braking.
ASE Anti Saturation Equipment
