Siemens SIMOTICS T-1FW6 Configuration Manual page 87

Depending on the mechanical design of the machine regarding elasticity and natural
oscillation, depending on the speed and grid spacing of the measuring standard, oscillation
can be excited and noise
generated.
Using a high-resolution optical measuring system, generally, when compared to other
techniques, the best dynamic performance, highest control quality, high noise immunity,
precision and low noise can be achieved. Further, excitation of oscillation can be also avoided.
Preconditions to achieve this include:
• The overall mechanical system, including motor and encoder mounting, permits this
• Extremely stiff dynamic machine design to avoid the excitation of low-frequency mechanical
oscillation

General mechanical conditions
Take into account the permissible mechanical speed, limit frequency of the encoder and Control
Unit. When configuring, mounting and adjusting the encoder refer to the appropriate
documentation issued by the manufacturer!
Mechanical integration of the encoder
The mechanical integration of an encoder is defined by certain influencing factors, e.g.:
• The requirements specified by the encoder manufacturer (mounting specifications, ambient
conditions)
• The closed-loop motor control (commutation) requires an adequately precise connection
between the motor and encoder without any play
