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-motor control (commutation) requires an adequately accurate connection
between the motor and encoder without any play
● The closed-loop speed and position control requires that the encoder is integrated into
the mechanical structure with the highest possible stiffness and lowest possible vibration
● Using the encoder as an angle measuring system for the machine precision requires that
the encoder is connected as close as possible to the process
In addition to selecting a suitable encoder, the performance of the machine axis is essentially
determined by the integration into the overall mechanical system.
As a consequence, a general recommendation for integrating the encoder cannot be given
for all encoder types and axis concepts.
To ensure that the encoder is optimally integrated into the mechanical system, Siemens
offers its Mechatronic Support service, see Catalog. For additional information, please
contact your local Siemens office. You can find the "Technical Support" Internet link in
Chapter "Introduction".
Two options for integrating an encoder are shown as example in the following example.
