Typical ratings:
Normal use (10% overload capability)

n
continuous rms current. 10% overload is allowed for one
minute in ten minutes.
P
n
typical motor power in normal use. The kilowatt power
ratings apply to most IEC, 4-pole motors. The Horsepower
ratings apply to most 4-pole NEMA motors.
Sizing
The current ratings are the same regardless of the supply
voltage within one voltage range. 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.
NOTE: The ratings apply in ambient temperature of 40 °C
(104 °F).
Derating
The load capacity (current and power) decreases for certain
situations,asdenedbelow.Insuchsituations,wherefull
motor power is required, oversize the drive so that the derated
valueprovidessufcientcapacity.
For example, if your application requires 15.4 A of motor
current and a 12 kHz switching frequency, calculate the
appropriate drive size requirement as follows:
The minimum size required = 15.4 A / 0.80 = 19.25 A
Where: 0.80 is the derating for 12 kHz switching frequency
(see Switching frequency derating below).

Temperature Derating
In the temperature range +40 °C…50 °C (+104 °F…122 °F)
the rated output current is decreased 1% for every 1 °C (1.8
°F) above +40 °C (+104 °F). Calculate the output current
by multiplying the current given in the rating table by the
derating factor.
Example: If the ambient temperature is 50 °C (+122 °F) the
deratingfactoris100%-1%/°Cx10°C=90%or0.90.

Altitude Derating
In altitudes from 1000…4000 m (3300…13,200 ft) above
sea level, the derating is 1% for every 100 m (330 ft). If the
installation site is higher than 2000 m (6600 ft) above sea
level, please contact your local Daikin distributor or office
forfurtherinformation.
Single Phase Supply Derating
For 208…240 Volt series drives, a single phase supply can be
used. In that case, the derating is 50%.
