Cause
Power unit power supply
failure.
Measurement circuit fault.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
Charging feedback signal
missing.
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
The motor parameters are set
incorrectly.
The drive is not dimensioned
correctly.
0001 Slip frequency is too small.
0002 Synchronous and nominal
speeds differ too much.
0003 Nominal speed is higher than
synchronous speed with 1 pole
pair.
0004 Nominal current is outside
limits
0005 Nominal voltage is outside
limits.
0006 Nominal power is higher than
apparent power.
0007 Nominal power not consistent
with nominal speed and
torque.
Parameters in group 99 have
not been set.
The voltage category has not
been defined.

What to do

Contact your local ABB representative.
Check the feedback signal coming from
the charging system.
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.
Check the settings of the motor
configuration parameters in groups 98
and 99.
Check that the drive is sized correctly for
the motor.
Check that all the required parameters in
group 99 have been set.
Note: It is normal for this warning to
appear during the start-up and continue
until the motor data is entered.
Set voltage category in parameter
Supply voltage.
