QEI Sensor Faults
QeiLsTck QEI Lost Ticks. The number of ticks
counted in two successive
index pulses is different
from the sensor resolution
configured by user.
There are several causes often seen:
1. The configured resolution is wrong. Please
check the Resolution configured according to
the encoder datasheet, and please pay
attention to the conversion between units
(Resolution = Cycles per Revolution * 4).
2. There's a loss of pulses in encoder
reading, which can be due to:
2a. 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.
2b. 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.
2c. The pulses are read with an exceeding
frequency. This case rarely happens, but can
be possible if the encoder resolution and/or
the spin speed being unusually high.
