Rexroth IndraDyn A Application Notes 9-1
9 Application Notes
9.1 Operating Conditions
Setup Elevation and Ambient Temperature
The performance data specified for the motors apply in the following
conditions:
• ambient temperatures of 0º C to +40º C,
• elevation between 0 and 1000 m above sea level.
If you want to use the motors in areas with values beyond these ranges,
the performance data are reduced according to the following figure.

Fig. 9-1: Utilization factors
If either the ambient temperature or the setup elevation exceeds the
nominal data:
1. Multiply the motor data provided in the selection data with the
calculated utilization factor.
2. Ensure that the reduced motor data are not exceeded by your
application.
If both the ambient temperature and the setup elevation exceed the
nominal data:
1. Multiply the determined utilization factors f
T and fH by each other.
2. Multiply the value obtained by the motor data specified in the
selection data.
3. Ensure that the reduced motor data are not exceeded by your
application.
