The guided commissioning takes the parameterized rated motor values and reference
data of the frequency inverter into account when it comes to pre-set-ting the V/f-
characteristic. In the case of asynchronous machines, the speed can be increased at a
constant torque if the motor winding can be switched over from star to delta connec-
tion. If the data for delta connec-tion indicated on the rating plate of the asynchro-
nous motor were entered, the cut-off frequency is increased automatically by the
square root of three.
