SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
Motors with star/delta changeover permit a wide constant power range.
At lower speeds, the motor is operated in the star circuit configuration
(high torque) and at higher speeds, in the delta circuit configuration
(high stall torque).
Assumptions for the example:
The motor is operated with drive A.
An optional TERMINAL module is used.
The changeover is realized via the following input/output terminals:
I8 (X422.5) P0668 (function, input terminal I8) = 6
O8 (X432.5) P0688 (signaling function, output terminal O8) = 11
O9 (X432.6) P0689 (signaling function, output terminal O9) = 13
P1247 = 700
i.e. 0 < n < 700 ––> motor in the star mode
n > 700 ––> motor in the delta mode
Application
