Cause
Communication errors
detected between the drive
control unit and the power unit.
Problem with measurement
circuit of power unit (analog to
digital converter)
Problem with current or voltage
measurement of power unit
State feedback from output
phases does not match control
signals.
Charging in progress
Adequate motor control at
requested output frequency
cannot be reached because of
limited switching frequency
(eg. by parameter 95.15).
The battery of the control unit
is low.
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
An error in saving data to the
power unit.
0 An error is preventing saving
from initializing.
1
2 Write error.
Error related to SD card used
to store data (BCU control unit
only).
1 No SD card
2 SD card write-protected
3 SD card unreadable
The calculated parameter
checksum does not match any
enabled reference checksum.

What to do
Check the connections between the drive
control unit and the power unit.
Contact your local ABB representative.
Contact your local ABB representative.
Contact your local ABB representative.
Informative warning. Wait until charging
finishes before starting the inverter unit.
Informative warning.
Replace control unit battery.
This warning can be suppressed using
parameter 31.40.
Avoid forcing unnecessary parameter
saves by parameter 96.07
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.
Check the auxiliary code. See actions for
each code below.
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.
Check the auxiliary code. See actions for
each code below.
Insert a compatible, writable SD card into
the SD CARD slot of the BCU control
unit.
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
enable a checksum parameter and copy
the actual checksum into that parameter.
