Up tolOOm cable (shielded/unshielded) complies with the requirements of IEC60034-17 (general purpose motors). Above this cable length the risk of "double pulsing" increases.

Provides a sinusoidal phase-to-phase motor terminal voltage. Complies with IEC-60034-17*and NEMA-MG1 requirements for general purpose motors with cables up to 500 m (1 km forframe size D and above).

Slightly reduced, only in high power motors.

Reduces bearing currents caused by circulating currents. Does not reduce common-mode currents (shaft currents).

Eliminates motor cable ringing. Does not change the emission class. Does not allow longer motor cables as specified for the frequency converter's built-in RFI filter.

Eliminates motor cable ringing. Does not change the emission class. Does not allow longer motor cables as specified for the frequency converter's built-in RFI filter.

100 m ... 150 m

With guaranteed EMC performance: 150 m screened Without guaranteed EMC performance: 150 m unscreened

With guaranteed EMC performance: 150 m shielded and 300 m unshielded (only conducted emissions). Without guaranteed EMC performance: up to 500 m (1 km for frame size D and above).

Does not eliminate acoustic switching noise.

Eliminates acoustic switching noise from the motor caused by magnetostriction.
