Star-Delta Starter 1 - ABB UMC22-FBP Technical Description

Universal Motor Controller UMC22-FBP
Software version 4.0
Chapter 7.5.1~1 Star-delta starter 1

7.5 Star-delta starter 1

The UMC22 parameterized with the Control function = Star-delta starter 1 provides excellent protec-
tion and control of a motor for one direction of rotation including the time or current controlled star-
delta transition. The connection to a fi eldbus is made via the appropriate type of the FieldBusPlug.
