ABB ACS850 machinery drives
ABB machinery drives are designed to meet the production
and performance needs of machine builders, system
integrators, panel builders and end users in a broad range
of applications. ACS850 drives are ideal for applications like
cranes, extruders, conveyors, winders, pumps, fans and
mixers in industries such as material handling, plastic and
rubber, food and beverage, textile and metals.
The drives can be configured to meet the precise needs
of industries and order-based configuration is an integral
part of the offering. Covering a wide power and voltage
range with standard and optional features, the drives are
readily programmable, making their adaptation to different
applications easy.
Wide range of options
ACS850 drives offer a wide range of built-in options such
as different I/O and communications. A wide selection of
external accessories is also available. The flexibility and
programmability of the drives make them suitable for many
applications in different industries.
Introduction to ACS850
Robust design
The current ratings of ABB machinery drives are designed for
applications that have a high overload requirement. At the
heart of the drive is the motor control platform, direct torque
control (DTC) that provides accurate motor torque and speed
control even without feedback. The drive is designed for a
long working life and as such, parts like fans and capacitors
are selected to maximize their lifetime. This, together with
the extensive protection features and design details such
as coated boards, results in excellent reliability for the
demanding industrial market.
Optimized cabinet assembly
ACS850 drives are designed to be built into a customer’s
own cabinet, using minimal cabinet space while ensuring that
cabinet assembly is as easy as possible. The drives can be
mounted side-by-side and cabinet assembly documentation
is included. The documentation gives examples of different
cabinet configurations, examples of drawings and hints on
the selection of auxiliary equipment
