Note
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 several 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
• 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.
To ensure that the encoder is optimally integrated into the mechanical structure,
Siemens offers its Application & Mechatronic Support Direct Motors service. For
