1.6.2 2. Example: motor 100L/4

Motor type plate information:

Nominal voltage 400/690 V

Nominal frequency: 50 Hz

Nominal power: 2.2 kW

Due to the different design of the windings only the 50 Hz characteristic curve can be used with

the frequency inverter.

This type of winding is typically used for gentle starting with star/delta circuits. The motor is started in

the star circuit (690 V / 50 Hz) and switched to the delta circuit (400 V / 50 Hz) in operation.
