Dear Vagabund, Kindly find here under an overview for both LC filter and output chokes copied from cataloge: LC filter and sinusoidal filterThe LC filter/sinusoidal filterlimits the rate of rise of voltage and the capacitive charge/discharge currents which usually occur with inverter operation. This means that much longer shielded motor cables are possible when using LC filters/sinusoidal filtersand the service life of the motor achieves values similar to those with direct mains operation. Use of an output choke isn't required with that. Please note when using LCfilters/sinusoidal filters:
The LC filters/sinusoidal filterscan be used for all MICROMASTER 440 inverters of frame sizes A to GX.
Output chokeOutput chokes can be supplied for reducing the capacitive compensation currents and dV/dt in the case of motor cables > 50 m (shielded) or > 100 m (unshielded). For max. permissible cable lengths, see the following link:

New question published by vrp is split to a separate thread with the subject Why un-shielded cables of more length can be used compared to shielded cables?. Best regards |
