9.2 Humidity
Climatic environmental conditions are defined into different classes
according to DIN EN 60721-3-3, Table 1. They are based on
observations made over long periods of time throughout the world and
take into account all supply parameters that could have an effect, such
as the air temperature and humidity.
Based on this table, Rexroth recommends class 3K4 for continuous use
of the motors.
This class is excerpted in the following table.

9.3 Vibration and Shock
Vibration
Sinusoidal vibrations occur in stationary use; depending on their
intensity, they have different effects on the robustness of the motors.
The robustness of the overall system is determined by the weakest
component.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following
values result for Rexroth motors:
Direction Maximum permitted vibration load (10-2000 Hz)
axial i.p.
radial i.p.

Shock
The shock load of the motors is indicated by providing the maximum
permitted acceleration in non-stationary use, such as during transport.
Damage to functions is prevented by maintaining the provided limit
values.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following
values result for Rexroth motors:
