NOTE!
(1) The power rating in VA is determined by the following
equation:
P(kVA)=
The values shown in the table were calculated by considering
the rated inverter current, input voltage of 220V.
(2) Rated current is valid for the following conditions:
Relative air humidity: 5% to 90%, non condensing.
Altitude: 1000m (3300ft), up to 4000m (13200ft) with
1% derating each 100m (330ft) of the rated current.
Ambient temperature: 0ºC to 50º C (32ºF to 122ºF).
The rated current values are valid for the switching
frequencies of 2.5kHz or 5kHz (factory setting= 5kHz).
For higher switching frequencies, 10kHz to 15kHz,
consider the values shown in the description of the
parameter P297(refer to chapter 6).
(3) Maximum Current:
Inverter supports an overload of 50% (maximum output
current = 1.5 x the rated output current) during 1 minute
for each 10 minutes of operation.
For higher switching frequencies, 10kHz to 15kHz,
consider the values shown at the description of the
parameter P297(refer to chapter 6).
(4) The indicated motor power ratings are only orientative values
for IV-pole motors and normal duty loads. The precise in-
verter sizing must consider the actual motor nameplate
and application data.
(5) WEG inverters are supplied with parameter settings for
WEG IV pole standard motors, 60 Hz, 220V and outputs
as indicated above.
