4.5.2 Encoder connector [X2B]
The 15-pin D-SUB connector [X2B] can be used for the feedback of encoder-equipped motors. Possible incremental encoders
for the encoder connector can be divided into several groups. If you want to use other types of encoders, please contact your
sales partner.

Standard incremental encoders without commutation signals:
This type of encoder is used for low-cost linear motor applications in order to save the costs for the provision of the
commutation signals (Hall sensor). With this type of encoder, the item Servo Positioning Controller C 3-Series must perform an
automatic pole position determination after power-on.
Standard incremental encoders with commutation signals:
This variant uses standard incremental encoders with three additional, binary Hall sensor signals. The line count of the
encoder can be parameterised as desired (1 to 16,384 lines/revolution).
There is an additional offset angle for the Hall sensor signals. It is determined during the motor identification process or it can
be set via the item Motion Soft
®
parameterisation software. Normally, the Hall sensor offset angle is zero.
