Bit 3 Initialization of HIPERFACE
®
-encoder assigned to the analog signal
If the bit is set, the analog tracks at initialization of absolute encoders with HIPER-
FACE
®
-interface are used. This achieves a higher initialization accuracy. The precon-
dition must be an assignment of the digital position information to the analog tracks
according to the HIPERFACE
®
-specification. The delivery status of encoders have this
assignment. However, this status can be changed by overwriting the digital position of
the encoder.
If this option is set and the assignment is not specified, error 402 occurs at initialization
of the encoder.
This bit is set to zero at all other encoder types.
106.4
Oversampling factor
Oversampling factor for encoder evaluation.
Meaning of the values:
10 Addition of the revolutions
of the overflow count on the
actual position value 0: The
Z
106.15
–
revolution overflow counter
is not used during the encoder initializa-
tion to generate the actual positioning
value (
Z
106.11
–
or
Z
106.12
–
).
1: The revolutions of the overflow counter
are added to the position actual value.
Bit 7 of the
Z
106.3
–
is not relevant in this
case.

Bit Meaning Remark
NOTE!
The automatic signal correction should be used only during commissioning. As soon
as the values for the gain and for the offset correction are determined, the automatic
signal correction should be deactivated and the correction values should be saved
with the parameter set.
At square-wave incremental encoders this function can only be used up to a 18 kHz
signal frequency.
Value Meaning
0 no oversampling
1 2-fold oversampling
2 4-fold oversampling
3 8-fold oversampling
4 16-fold oversampling
