500 m
-With sinusoidal filter on the inverter output
5000 m
Motor cable length to meet
IEC61800-3:2017 standard
0 ... 200 m (shielded according to IEC60034-25)
(1)
This output frequency range is valid considering the factory settings (e.g., rated switching frequency). It is possible to operate with higher
output frequencies, limited to 1000 Hz, but the rated switching frequency must be increased. In these cases, WEG must be consulted.
(2)
The switching frequency can be automatically reduced due to inverter output overload, high ambient temperature, obstruction of air
circulation around the heatsink and/or operation with low output frequency.
(3)
For operation with a switching frequency above the rated switching frequency (fsw,nom) it is necessary to reduce the output current according
to
(4)
Adjustable in 0.1 kHz steps.
(5)
The modulation type can be changed in parameter C1.4.1.
