Contents of this chapter
This chapter briefly describes the operation principle and construction of the drive.
Operation principle
The ACS880-07 is an air-cooled cabinet-installed drive for controlling asynchronous
AC induction motors, permanent magnet synchronous motors, ABB synchronous
reluctance (SynRM) motors and AC induction servomotors.
The drive consists of several cubicles that contain the supply and motor terminals, 1
to 4 diode supply module(s), 2 to 5 inverter modules, and optional equipment. The
actual arrangement of the cubicles varies from type to type and the selected options.
