
Ambient temperature derating
In the temperature range +40…50 °C (+104…122 °F), the rated output current is derated
by 1% for every added 1 °C (1.8 °F) as follows. Calculate the output current by multiplying
the current given in the rating table by the derating factor.

Hd
Typical motor power for heavy-duty use.
Note: To achieve the rated motor power given in the table, the rated current of the drive must be higher than
or equal to the rated motor current. The power ratings apply to most IEC 34 motors at the nominal voltage of
the drive.
We recommend to select the drive, motor and gear combination for the required motion profile with the
DriveSize dimensioning tool available from ABB.
