QeiNoIdx
QEI No Index.
For an incremental
encoder configured to be
with 3 channels (usually
known as ABI/ ABZ), the
drive is expecting to
receive an Index pulse
which provides an index
for the absolute
singleturn position.
This error indicates that
the Index pulse couldn't
be detected, while the
drive moved the motor in
order to detect it.

Please first check whether your
encoder is indeed with the Index
pulse, i.e. is an ABI/ ABZ encoder. If
it is an encoder without index,
please choose 2-channel (no index)
for Number of channels.
Else, most probable causes are:
1. The encoder being improperly
mounted, or the encoder ring is
damaged. Please check the
mounting instruction of your
encoder for proper installation,
and consult the encoder
manufacturer for advices.
2. Inconsistency in signal transfer.
Please check the signals received
by the drive with an oscilloscope
under operation for better
investigation. The cause can be
that the signal transfer is
influenced by external field, or that
the signal transfer is unstable for
example due to soldering quality
or cable aging. Improve the
situation by replacing the cables,
better arranging the cables, adding
shielding, etc., ensuring that the
signals can be stably transfered
with acceptable noise.

QEI Open Wire. Indicate that one of the
differential A or B lines is
disconnected. Only
available on hardware
that supports it.

Please check the wiring with for
example the diode mode of a
multimeter, making sure that the
wires are stably transfering the
signals.
