For this reason, before using the respective material a compatibility test has to
be carried out for new lubricants, cleaning agents etc. and our housings/our
housing materials.
Where installation conditions differ, the following performance data are reduced
in accordance with the diagrams:
Drive controller:
● allowed DC bus continuous power P
● braking resistor continuous power P
● continuous current I
Motor:
● power
● continuous torque at standstill
● S1 continuous torques
● short-time service torque MKB
If differing ambient temperatures and higher installation altitudes occur simul‐
taneously, both capacity utilization factors must be multiplied. The installation
altitude must only be taken into account once, deviating ambient temperatures
must be taken into account separately for motor and drive controller.
Use outside of the indicated installation conditions is not allowed,
even if the performance data are additionally reduced.
As the ambient temperature increases, the capacity utilization of the devices is
reduced according to the figure below.

As the installation altitude increases, the capacity utilization of the devices is
reduced according to the figure below.
