ABB ACS850 Machinery drives

ABB ACS850 Machinery drives

DESCRIPTION

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.

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.
