Removable memory unit
A rem ovable memory unit provides easy maintenance
by storing the com plete firmware, including all user
settings and motor data.
■ Stores the drive software and parameter settings
■ Fast and easy recommissioning
■ Enables software and parameter configuration at
workshop instead doing on-site

Pre-programmed protection functions
A wide range features provides protection for the
drive, motor and the process.7.
The ACS850 standard program provides solutions to
virtually all drives applications such mixers,
separators, extruders and conveyors, nam few. Thus, the power unit
or control unit replaced, the drive can be
re-com issioned without any reprogramming, just
move the memory unit.Programming
Based Direct Torque Control technology, the
ACS850 offers highly advanced features standard.
Programmable protection functions
■ Adjustable power limits
■ Control signal supervision
■ Critical frequencies lock-out
■ Current and torque limits
■ Earth fault protection
■ External fault
■ Motor phase loss
■ Motor stall protection
■ Motor thermal protection
■ Motor underload protection
■ Panel loss
Program customization
Using DriveSPC allows fine-tuning the standard
program fit any application.
■ Ambient temperature
■ overvoltage
■ undervoltage
■ Drive temperature
■ Input phase loss
■ Overcurrent
■ Power limits
■ Short circuit
Furthermore the standard application program offers
an integrated ergency stop and supports the
functionality prevention unexpected start-up. addition to
parameters, ABB industrial drives offer function block
programming, this akes possible replace relays
or even PLC, som applications.2009 Control 133

Fast and easy commissioning
The standard ACS850 program offers flexibility and
extensive parameter settings. Commisioning is
also simplified several software features that com e
standard with every drive. consists simple,
ready-made program that can easily modified to
m eet specific application needs
