4.2.2 Information on the motor–drive converter selection, IM analog
The converter must be selected according to the required duty cycle.
Further, the following restrictive conditions must be observed:
S The motor no–load current must be less than the rated current of the drive
converter module (IM according to Table 4-6).
S As result of the current actual value resolution, the lowest no–load motor
current must fulfill the following condition:

S For motors with a low leakage induction, it may be necessary to provide a
series reactor and/or increase the inverter clock frequency of the drive con-
verter. From experience, motors with low leakage induction are those which
can achieve high stator frequencies (maximum motor stator frequency
>
300 Hz) or motors with a higher rated current (rated current > 85 A).
