SsiChksm SSI Checksum
error.
Some SSI slaves include a
ckecksum of the data in
the SSI frame. Currently
our drives can be
configured to read a parity
bit from compatible SSI
encoders. This error
means the parity bit
computed by the firmware
is different than the one
sent by the SSI slave.
Regarding a checksum error, there are
several causes often seen:
1. Misconfiguration of the sensor leading to
the bits being read wrong or the checksum
being calculated wrong. In this case the fault
cannot be reset. Please check the sensor
configuration according to the
documentation of the encoder
manufacturer.
2. Inconsistency in signal transfer. In this
case the fault can sometimes be reset, but
would occur under certain circumstances.
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.
