AftFrame A-Format
Frame error.
The fixed data in the
recieved A-Format frame
(like sync code) is wrong.
This usually means that
the A-Format transmission
speed is wrong.
Please check the transmission speed
configuration according to the encoder
datasheet.
AftTmout A-Format
Timeout.
The A-Format encoder
didn't start
communication after
sending a request.
Please check the wiring and make sure that
the signals are transfered with good
consistency. Use a oscilloscope to monitor
the signal transfered for further
investigation.
AftCrc A-Format CRC
error.
The A-Format frame
contains a CRC of some of
the data that is being sent.
This error is raised when
the CRC sent by the
encoder is different than
the CRC computed by the
drive. This usually means
that the drive can't read
the frame properly, which
usually happens because
of noise in the
communication link.
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.
AftBatt A-Format BATT
status.
The encoder is raising
Battery Alarm. Check your
A-Format encoder
datasheet for more
information.
Please check the encoder documentation for
better understanding the meaning of the
Battery Alarm. The usual case is that the
battery voltage is low, the battery is wrongly
wired, or there's no battery connected.
AftMTErr A-Format
MTERR status.
The encoder is raising MT
Error. Check your A-
Format encoder datasheet
for more information.
Please check the encoder documentation for
better understanding the meaning of the MT
Error.
AftOvFlw A-Format
OvFlow status.
The encoder is raising
Over Flow Alarm. Check
your A-Format encoder
datasheet for more
information.
Please check the encoder documentation for
better understanding the meaning of the
Over Flow Alarm.
AftOvSpd A-Format
OVSPD status.
The encoder is raising
Over Speed Alarm. Check
your A-Format encoder
datasheet for more
information.
Please check the encoder documentation for
better understanding the meaning of the
Over Speed Alarm. The usual case is that the
rotation speed exceeds the speed limit of the
encoder.
AftMemEr A-Format
MEMERR
status.
The encoder is raising
Memory Error. Check your
A-Format encoder
datasheet for more
information.
Please check the encoder documentation for
better understanding the meaning of the
Memory Error.
