Geared Motor With Encoder For Safety-Relevant Applications - Siemens SIMOGEAR BA 2330 Operating Instructions Manual

Vibration severity
Due to the influencing variables listed below, the vibration response of the system at the
location of use can lead to increased vibration severity on the drive unit:
• Transmission elements
• Installation conditions
• Alignment and installation
• Effects of external and internal oscillation
The vibration severity values specified in accordance with ISO 20816-1 must not be exceeded
at any point on the surface of the drive. This ensures problem-free operation and a long
service life.
Maximum permissible vibration severity
Observe the values for the maximum permissible radial and axial oscillation vibration severity
in the following table. Radial/axial refers to the motor axes.
Maximum permissible radial vibration levels
Vibration frequency
< 6.3 Hz
6.3 Hz to 250 Hz
> 250 Hz
Maximum permissible axial vibration severity
Vibration velocity
Vibration velocity v
Resonant frequencies
Resonance can occur in the speed range of the geared motor depending on the machine to
be driven.
Operation in resonance causes increased noise and vibration levels.
Adherence to the maximum permissible vibration severity is always required.
Operation in the resonant frequency leads to a reduced service life of the geared motor,
irrespective of adherence to the maximum vibration severity.
Continuous operation in the resonant frequency must be avoided.

Geared motor with encoder for safety-relevant applications

For a SIMOGEAR geared motor with rotary encoder for safety-relevant applications, carefully
observe the information provided in operating instructions BA 2331 or BA 2730 These operating
instructions are valid for functionally safe rotary encoders that are mounted onto SIMOGEAR
geared motors. The functionally safe rotary encoders are in compliance with the relevant
standards for safety-relevant applications listed in the Declaration of Conformity of BA 2730.
