Note 1: The ratings apply at an ambient air temperature of 45 °C (113 °F) and a coolant 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 +45…55 °C (+113…131 °F), the rated output current is derated
by 0.5 percentage points 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

Altitude derating
At altitudes from 0 to 2000 m (0 to 6562 ft), no derating is required. For altitudes above 2000
m (6562 ft), contact ABB.
Switching frequency derating
Switching frequencies other than default can require output current derating. Contact ABB
for more information.
