10.2 De-rating
The drive can be operated at above the rated ambient temperature, altitude and default carrier frequency by de-rating the drive
capacity.
Ƶ
Carrier Frequency De-rating
When the carrier frequency of the MD500 AC drive is increased above the default setting, you need to de-rate the drive's rated
output current according to the following table:

Ƶ
Ambient Temperature De-rating
The 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. The rated output current must be de-rated for 1.5% per 1°C. The allowable maximum temperature is 50°C.
Ƶ
Altitude De-rating
The MD500 AC drive must be de-rated for an installation altitude of above 1000 meters because the cooling effect available from
ambient air reduces. The rated output current must be de-rated for 1% per 100 meters. The maximum altitude is 3000 meters.
