9-2 Application Notes Rexroth IndraDyn A
9.2 Humidity
Environmental conditions are differentiated by class according to DIN EN
60721-3-3 (1995), 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.
The following table provides an excerpt of this class:

9.3 Vibration and Shock
Vibration
Vibrations occur in stationary use and, depending on their intensity, 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
are permissible for Rexroth motors:
Direction
Amplitude
0 – 55 Hz
Acceleration
55 – 2000Hz
axial 0.3 mm 1 m/s²
radial 0.75 mm
30 m/s²
(10 m/s² when used with M2/S2
encoders)
