ABB ACS880-104

574 Fault tracing
A682 Flash erase speed
exceeded
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
Avoid forcing unnecessary parameter
saves by parameter 96.07 or cyclic
parameter writes (such as user logger
triggering through parameters).
Check the auxiliary code (format XYYY
YZZZ). “X” specifies the source of
warning (1: generic flash erase
supervision). “ZZZ” specifies the flash
subsector number that generated the
warning.
A683 Data saving to power
unit
An error in saving data to the
power unit.
Check the auxiliary code. See actions for
each code below.
0 An error is preventing saving
from initializing.
Cycle the power to the drive. If the
control unit is externally powered, also
reboot the control unit (using parameter
96.08 Control board boot) or by cycling
its power. If the problem persists, contact
your local ABB representative.
1
2 Write error.
A684 SD card Error related to SD card used
to store data (BCU control unit
only).
Check the auxiliary code. See actions for
each code below.
1 No SD card Insert a compatible, writable SD card into
the SD CARD slot of the BCU control
unit.
2 SD card write-protected
3 SD card unreadable
A686 Checksum mismatch
Programmable warning:
96.54 Checksum action
The calculated parameter
checksum does not match any
enabled reference checksum.
Check that all necessary approved
(reference) checksums (96.56…96.59)
are enabled in 96.55 Checksum control
word.
Check the parameter configuration.
Using 96.55 Checksum control word,
enable a checksum parameter and copy
the actual checksum into that parameter.
A687 Checksum
configuration
An action has been defined for
a parameter checksum
mismatch but the feature has
not been configured.
Contact your local ABB representative for
configuring the feature, or disable the
feature in 96.54 Checksum action.
A688 Parameter map
configuration
Too much data in parameter
mapping table created in Drive
customizer.
See the Drive customizer PC tool user’s
manual (3AUA0000104167 [English]).
A689 Mapped parameter
value cut
Parameter value saturated eg.
by the scaling specified in
parameter mapping table
(created in Drive customizer).
Check parameter scaling and format in
parameter mapping table. See the Drive
customizer PC tool user’s manual
(3AUA0000104167 [English]).
A6A4 Motor nominal value The motor parameters are set
incorrectly.
Check the auxiliary code. See actions for
each code below.
The drive is not dimensioned
correctly.
