*) Basic oscillation, measured at the motor terminals.
The voltage depends on the input voltage of the frequency inverter, the voltage drop at the filter and
over the motor supply cable and may not fall below the design value by more than 5% according to
IEC 60034 - 1 Range "A", even with minimum input voltage of the frequency inverter. This must be
taken into account for the design of the motor, the parameterisation of the inverter (e.g. rev/f
adaptation) and for the minimum input voltage of the inverter.
The maximum input voltage of the inverter is 500V.
Adaptation of the design voltage of the motor by means of the number of windings is permissible. The
rated current changes in inverse proportion to the rated voltage.
