always observe the information in the most-current drive controller
documentation.
The accuracy of encoder systems is only a secondary factor for
the precision of processing and positioning processes in a system.
Determining factors for the precision that can be attained include the
functions of the system and the quality of the mechanical construction,
among other things.
Connection of the Encoder
The encoder connection is always on the same side of the motor as the
power connection. The position of the encoder connection can not be
changed after the motor has been delivered. For additional details, refer
to the dimension sheet of the motor and to Chapter 8 "Connection
Technique".
Detailed information on the encoder connection to the controller,
and on the setting of its parameters can be found in the documentation of
the drive controllers.
9.12 Output Shaft
Plain Shaft
The recommended standard model for all IndraDyn A motors provides a
friction-type, zero-backlash, shaft-hub connection with a high degree of
quietness. Use clamping sets, thrust sleeves or clamping elements to
couple the machine elements to be driven by the motor.
Output Shaft with Key
An optional keyed output shaft, according to DIN 6885, Sheet 1, edition
08-1968, permits form-fitting transmission of torque for non-reversing with
low requirements on the shaft-hub connection.
