Definitions
The ratings are valid at a maximum surrounding air temperature of 50 °C (122 °F),
with the default drive switching frequency of 4 kHz (parameter 97.01), and with
an installation altitude below 1000 m (3281 ft).
U
n
Nominal input voltage of the drive. For input voltage range U1, refer
to Electrical power network specification (page 166).
I
1n
Nominal input current with typical motor power P
n
. Continuous rms
input current, for dimensioning cables and fuses.

Ld
, for
dimensioning cables and fuses.
I
max
Maximum output current. Available for 2 seconds every 10 minutes
when the output frequency is less than 9 Hz. Maximum current setting
(parameter 30.17 ) can also limit the value.
I
n
Nominal output current. Maximum continuous rms output current
(no overload).
P
n
Typical motor power in nominal use (no overloading). The kilowatt
ratings are applicable to most IEC 4-pole motors.
I
Ld
Continuous rms output current. Allows 10% overload for 1 minute
every 10 minutes.
P
Ld
Typical motor power in light-duty use (10% overload). The kilowatt
ratings are applicable to most IEC 4-pole motors. The horsepower
ratings are applicable to most NEMA 4-pole motors.
