Sine-wave filters are available in the voltage range 380 V to 480 V up to a type rating of 250 kW, and in the voltage range 500 V to 600 V up to a type rating of 132 kW.

The sine-wave filter at the converter output supplies almost perfect sinusoidal voltages on the motor so that standard motors can be used without special cables or power derating. Standard cables can be used.

Note the following when a sine-wave filter is used:

• The output frequency is limited to max. 150 Hz (at 380 to 480 V) and 115 Hz (at 500 to 600 V).
• The maximum output voltage is limited to approx. 85% of the input voltage.
• Maximum permissible motor cable lengths:
  • Unshielded cable: 450В m
  • Shielded cable: 300В m
• During commissioning, the pulse frequency is increased to double the factory setting. This induces current derating, which must be applied to the built-in units' rated currents listed in the technical specifications.

Note:

The reduced voltage at the motor terminals compared to the rated motor voltage means that the motor reaches the field weakening range earlier.

The sine-wave filter may be operated only when the motor is connected; sine-wave filters are not no-load-proof!
