6.2 POWER LOSS (HEAT DISSIPATION)
When the ACE Series enclosure is not installed in a well ventilated area,
provisions must be made to account for heat generation and ensure
proper operation of the device.
6.3 DE-RATING FACTORS
The final drive output rating is a multiplication of all applicable de-rating
factors.
Factors are given as a percentage of rated output current.
6.3.1 AMBIENT TEMPERATURE DE-RATING
As standard, each drive is rated for its full output current in
CT/IH (Constant Torque with High Overload) at 50°C ambient
temperature*.
For ambient temperatures above 50°C and not exceeding 60°C, the
de-rating is 5% per °C. *100HP is rated for full output current at 40°C.
6.3.2 ALTITUDE DE-RATING
At altitudes from 1,000m to 3,000m (3280ft to 9840ft) above sea level,
the de-rating is 1% per 100m (328ft).
NOTE: If the installation site is higher than 2,000m (6,560ft) above sea
level, connection of the drive to an ungrounded (IT) or corner-grounded
delta network is not allowed.
6.3.2 SWITCHING FREQUENCY DE-RATING
To reduce motor noise, a higher switching frequency may be desired.
Note that this will increase heat output from the drive.
For switching frequencies above the factory default, the de-rating is 6%
per 1kHz.
