■ 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:

Power	Carrier Frequency

18.5	100.0%	100.0%	100.0%	100.0%	95.7%	91.6%

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.

(3) 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 bede-rated for 1% per 100 meters. Maximum altitude is 3000 meters.
