9.8 Derating
When dimensioning the drive, observe the derating for:
•
An installation altitude above 1000 m (factor D
h
)
• An ambient temperature other than 40°C (factor D
T
)
The total derating is calculated as follows:
The admissible torque M
perm.
can be calculated from D
total
:
9.8.1 Installation altitude
Example
The drive is to be installed at an altitude of 1500 m above sea level.
According to the diagram, the admissible torque is approx. 95% of the rated torque M
N
at this altitude. Hence D
h
= 0.95.
