Error group 8 Angle encoder error
No. Reaction Message Code
8-1 - Direction of rotation of the serial and incremental position
evaluation is not identical
configurable
Cause Only encoders with serial position transmission combined with an
analogue SIN/COS signal track: The directions of rotation for posi­
tion determination in the encoder and for incremental evaluation of
the analogue track system in the motor controller are the wrong
way round Additional informationrmation.
Measure Swap the following signals on the [X2B] angle encoder interface
(the wires in the connecting plug must be changed around), ob­
serving the technical data for the angle encoder where applicable:
– Swap SIN / COS track.
– Swap the SIN+/SIN- or COS+/COS- signals, as applicable.
Additional
informa­
tion
The encoder counts internally, for example positively in clockwise
rotation, while the incremental evaluation counts in negative direc­
tion with the same mechanical rotation. The interchange of the
direction of rotation is detected mechanically at the first movement
of over 30°, and the error is triggered.

Incremental encoder Z0 track signals error
configurable
Cause Signal amplitude of the Z0 track at [X2B] is faulty.
– Angle encoder connected?
– Angle encoder cable defective?
– Angle encoder faulty?
Measure Check configuration of the angle encoder interface:
a) Z0 evaluation activated, but no tracking signals connected or on
hand Additional informationrmation.
b) Encoder signals faulty?
c) Test with another encoder.

Additional
informa­
tion
For example, EnDat 2.2 or EnDat 2.1 without analogue track.
Heidenhain encoder: order codes EnDat 22 and EnDat 21. With
these encoders there are no incremental signals, even when the
cables are connected.
