Ambient temperature – general terms

Designed for variable speed control of
all induction motors and permanent
magnet motors, on any industrial
machine or production line, a VLT®
AutomationDrive FC 300 helps its
owner save energy, increase flexibility,
and optimize processes.

98%

energy efficiency
with flexible robust
operation in a wide
temperature range

n The definition of ambient and

cooling temperature is according to
EN50178, and IEC721-3-3 class 3K3.

n The drive can operate at elevated

ambient temperatures up to +55 °C,
however, the rated current must be
de-rated (please refer to the
derating chart below).

n Do not operate in environments

where the ambient temperature
exceeds 55 °C (131 °F). If the
temperature exceeds ambient
temperature limits, extra air
conditioning of the cabinet or
installation site is required.

Ambient temperature for operation and derating

n All products listed are able to work

at the below given ambient
temperature without any condition
/influence on the fulfillment of
specifications”

n Ambient temperature:

-10 °C to +45 °C

n Ambient temperature:

+45 °C to 55 °C with derating
(refer derating table)

n The drive can operate at

temperatures down to -10 °C (14 °F).
However, proper operation at rated
load is only guaranteed at 0 °C
(32 °F) or higher.

n Temperature range during storage /

transport is -25 to 65/70 °C
(-13 °F- 149/158 °F).

n Avoiding extreme ambient

temperatures prolongs the life of
the equipment and maximizes
overall system reliability.

n As a rule of thumb, the lifetime of

electronic components decreases
by 50% for every 10 °C when
operated above its design
temperature.

n All products listed are able to work

at ambient temperatures up to
50 °C without derating if certain
conditions are met/followed:.

n Applicable for EEF2 Class motors
n Reduce Switching frequency

(refer derating chart)

n Change switching mode to

“60 AVM” from “SFAVM”

n Derate the output current at high

temperatures. This calculation takes
place after the calculations for
derating the switching frequency.

n The result is an attempt to lower the

temperatures by first lowering the
switching frequency, and then
lowering the output current.

n Current derating only takes place if

the user has programmed the unit
to derate in overtemperature
situations. If the user has selected a
trip function for overtemperature
situations, the current derate factor
is not lowered.
