1.5 De-rating
The drive can be operated at above rated ambient temperature, altitude and default carrier frequency by
de-rating drive capacity.
■
Carrier Frequency De-rating
When carrier frequency of the drive is increased above default setting, you need to de-rate rated
drive output current according to the following table:

■
Ambient Temperature De-rating
Drive operation between -10°C to 40°C is normal without de-rating. Operation between 40°C and
50°C requires output current de-rating. Rated output current must be de-rated for 1.5% per 1°C
temperature rise. Permissible maximum temperature is 50°C.
■
Altitude De-rating
The drive must be de-rated for an installation altitude of above 1000 meters because cooling
effect available from ambient air reduces. Rated output current must be de-rated for 1% per 100
meters. Maximum altitude is 3000 meters.
