Cause
Power unit power supply failure.
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.
An error is preventing saving from
initializing.
Write error.
Error related to SD card used to store
data (BCU control unit only).
What to do
Contact your local ABB representative.
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 96.7
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 96.8 Control board
or by cycling its power. If the
problem persists, contact your local
ABB representative.
