This section provides details about the various options of the encoder interface. It
describes the manual configuration of the angle encoders connected to X1, X2A and
X2B/X6.

The Offset of encoder is the angle difference between the electrical and mechanical
position that results from the installation position of the angle encoder on the motor shaft.
In general, the angle encoder offset is determined automatically.
The phase sequence indicates the way of counting ("direction of rotation") of the angle
encoders and depends on the wiring. The correct setting of the phase sequence is
essential for the operation of the system. The phase sequence is also determined during
the automatic determination of the angle encoder offset.
The automatic identification can be started with the button Auto detect. Ensure that the
current limits have been set correctly and that the servo drive is free from errors. In
addition, the shaft must move freely. The automatic identification process determines the
following parameters:
l Number of pairs of poles
l Direction of rotation of the angle encoder/phase sequence
l Angle encoder offset
