11 The sign of the system deviation for the additional, free tech-
nology controller can be switched over.
A new parameter defines the sign of the system deviation
matching the particular application, e.g. for cooling or heating
applications.

13 Fast flying restart for PM330 Power Modules:
The "Flying restart" function does not have to wait for the motor
demagnetization time, and identifies the motor speed without
requiring a search operation.

this manual (Page 5).
A.2
Star-delta motor connection
Depending on your application, you can operate the motor in the star or delta connection
(Y/Δ).
