Remark: In this circuit diagram inner delta wiring of the motor is used. The current factor should be
set to 1,73 (3.2.3 and 4.3.4).
7.6 Star-delta starter 2
The UMC22 parameterized with the Control function = Star-delta starter 2 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.
Differences to control function Star-delta starter 1:
- For Star-delta starter 2 the number of switching cycles is the same for all 3 relais.
- Control function Star-delta starter 2 does not offern a fault output.
