Application range
Motor filters are applied to reduce the motor cable load and to decrease capacitive
discharge currents to PE in long motor cables.
A motor filter is required:
ƒ in very long motor cables (regardless of the compliance with EMC limit values)
– 50 m when low−capacitance shielded (max. 100 m)
– 100 m when unshielded (max. 200 m)
Motor cables must comply with EMC limit values only with regard to conducted
interference emission.
ƒ in combination with LD RFI filters (0.25 ... 11 kW)
– for reducing the conducted noise emission when long motor cablesare used
– for compliance with EMC limit class C1 or C2
ƒ When operating motors whose insulation systems are not suitable for inverter
operation. Lenze motors have insulations with greater thermal reserves.
Please note:
ƒ Operation is only permissible if a V/f or V/f
frequency of 2 ... 8 kHz is applied.
– The filter will overheat if it is operated at another switching frequency.
ƒ The frequency inverter is loaded with an additional 12 per cent, approximately, of the
rated current of the motor filter.
ƒ The voltage drop at the motor filter averages 2−3 per cent of the max. output voltage
of the frequency inverter if the rated current of the motor filter and a frequency of 50
Hz is applied.
