Note 1: The ratings apply at an ambient temperature of 40 °C (104 °F).
Note 2: 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 DriveSize dimensioning tool available from ABB is recommended for selecting the drive, motor and gear
combination.
￭ Derating
Ambient temperature derating
In the temperature range +40…50 °C (+104…122 °F), the rated output current is derated
by 1 pp for every added 1 °C (1.8 °F). The output current can be calculated by multiplying
the current given in the rating table by the derating factor
