VLT Power OptionDu/dt filters reduce the du/dt values on the motor terminal phase-to-phase voltage - an issue that is important for short motor cables. MCC 102 | | | Compared to sinewave filters, the du/dt filters have a cut-off frequency above the switching frequency. |
Range - 3 x 200 - 500 V, 24 - 2300 A
- 3 x 525 - 690 V, 28 - 1350 A
Enclosures - IP 00 and IP 20 enclosure in entire power range
Match for applications with short motor cables, applications with older motors, aggressive environments, applications with frequent braking, motor cable length up to 150 m. Highlights - Protects the motor against voltage peaks and high du/dt values hence prolongs the lifetime of the motor
- Allows the use of motors which are not specifically designed for converter operation, for example in retrofit applications
- Reduced size, weight and price compared to the sine-wave filters
- Possibility of connecting shielded cables with included decoupling plate
- Compatible with all control principle including flux and WC+
- Parallel filter installation is possible with applications in the high power range

Sine Wave FiltersSine-wave output filters are low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal. This reduces the motor insulation stress and bearing currents. MCC 101 | | | By supplying the motor with a sinusoidal voltage waveform, the switching acoustic noise from the motor is also eliminated. |
Range - 3 x 200 - 500 V, 2.5 - 1,200 A
- 3 x 525 - 690 V, 13 - 1,320 A
Enclosures - IP00 and IP20 enclosure in entire power range
Match for applications with older motors, aggressive environments, applications with frequent braking, 690 V applications with general purpose motors. Highlights - Protects the motor against dU/dt stress which prolongs the lifetime
- Lowers the frequency depending losses in the motor, eddy current losses and stray flux losses
- Diminishes acoustic switching noise on the motor
- Reduces semi conduct losses in the drive with long motor cables
- Decreases electromagnetic radiated emissions on unscreened motor cables
- Reduces voltage peaks
- Reduces electrical discharges in the motor construction thus prolonged bearing life time
- Compatible with all control principle including flux and WC+
- Parallel filter installation is possible with applications in the high power range
