1) The values refer percentage to the output rated current IN
2) The output frequency is to be limited in such way that 1/10 of the switching frequency is not exceeded.
3) Rated operation corresponds to UN=400 V; fSN; fA=50 Hz (typically value)
4) On reaching the temperature Tdr the switching frequency is step down. The switching frequency is increased again on cooling down to temperature
Tur.
5) At rated voltages > 460 V multiply the rated current with factor 0.86
6) The voltage at the motor is dependent on the series-connected units and on the control method (example see chapter A.1 in the annex)
The technical data are for 2/4-pole standard motors. With other pole numbers the inverter must be
dimensioned onto the motor rated current. Contact KEB for special or medium frequency motors.
The service life of the frequency inverter with intermediate voltage circuit depends on the current load
of the electrolytic capacitors in the intermediate circuit. The use of mains chokes can increase the
service life of the condensators to a considerable extent, especially when connecting to „hard“ power
systems or when under permanent drive load (continuous duty). For continuous duty (S1) drives with
a medium duty of >60%, KEB provided the use of mains chokes with a terminal voltage (Uk) of 4%.
The term "hard" power system means that the nodal point power (SNet) of the mains is very high (>>
200) compared to the output rated power of the inverter (SA).

e.g.
