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.
ABB recommends to select the drive, motor and gear combination for the required motion profile with the
DriveSize dimensioning tool available from ABB.
■
When is derating necessary
Derate the continuous output current of the drive if
• ambient temperature e40 °C (+104 °F) or
• drive is installed higher than 1000 m (3280 ft) above sea level
• switching frequency is other than default
• the minimum requirements of motor cable length are not met (see chapter d
u
/d
t
filters
and sine filters)
• DC voltage boost feature is used.
Note:
The final derating factor is a multiplication of all applicable derating factors.
■
Surrounding air temperature derating
In the temperature range +40…55 °C (+104…131 °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.
