ABB ACS255 Brochure
ABB micro drives
ACS255 600 V AC, 1 to 20 hp
ACS255 is an enhanced verison of the popular ACS250
drive series. Updates to the 600V drives include:
sensorless vector control for PM motors and sleep/
standby mode. These changes better harmonize
the featues of the 115-480V and 600V drives. All of
the existing features of the 600V ACS250 drives parameters, external dimensions, mounting locations,
etc. - are the same for the 600V ACS255.
ABB micro drive ACS255 with 600 V AC
supply offers easy to use and compact
solutions for general purpose low power
applications, such as; screws, mixers,
pumps, fans and conveyors. The key
features include a built-in safe torqueoff (STO), Modbus RTU and CANopen
communication interfaces.
