Ambient temperature – general terms
nThe definition of ambient and cooling temperature is according to EN50178, and IEC721-3-3 class 3K3.
nThe 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).
nDo 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.
nThe 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.
nTemperature range during storage / transport is -25 to 65/70 °C
(-13 °F- 149/158 °F).
nAvoiding extreme ambient temperatures prolongs the life of the equipment and maximizes overall system reliability.
nAs a rule of thumb, the lifetime of electronic components decreases by 50% for every 10 °C when operated above its design temperature.
Ambient temperature for operation and derating
nAll products listed are able to work at the below given ambient temperature without any condition /influence on the fulfillment of specifications”
nAmbient temperature: -10 °C to +45 °C
nAmbient temperature:
+45 °C to 55 °C with derating (refer derating table)
nAll products listed are able to work at ambient temperatures up to
50 °C without derating if certain conditions are met/followed:.
nApplicable for EEF2 Class motors
nReduce Switching frequency (refer derating chart)
nChange switching mode to “60 AVM” from “SFAVM”

Derating table for different power sizes and switching mode
n Derate the output current at high |
n The result is an attempt to lower the |
temperatures. This calculation takes |

derating the switching frequency. |
lowering the output current. |
nCurrent 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.
