is entered in parameter dr.50.

or
The motor name plate data are only valid for one operating state (generally at operating
temperature). With the motor parameter adaption the operational performance of
motors > 4kW for the respective operating state (cold...warm... max. temperature)
can be optimized . This function should not be activated (because the system can
oscillate) for smaller motors or applications which do not reach the torque limit. Para-
meters dr.50...dr.52 must be entered for activation. Equivalent circuit diagram data
listed in picture 6.5.17 must be taken from additional data sheets of the drive or you
can inquire the motor manufacturer. This function is only effective from 300 rpm and
approx. 10% of the rated current of the inverter.
The adaption in a range of 0 (off) to 65535 can be adjusted with CS.10 (starting value
approx. 2000). This adjustment should be controlled in several operating areas.
