A5A0 Safe torque off
Programmable warning:
31.22 STO indication
run/stop
Safe torque off function is
active, ie safety circuit signal(s)
connected to connector STO is
lost.
Check safety circuit connections. For
more information, chapter The Safe
torque off function in the Hardware
manual of the drive and description of
parameter 31.22 STO indication
run/stop (page 180).
Check the value of parameter 95.04
Control board supply.
A5EA Measurement circuit
temperature
Problem with internal
temperature measurement of
the drive.
Contact your local ABB representative.
A5EB PU board powerfail Power unit power supply
failure.
Contact your local ABB representative.
A5ED Measurement circuit
ADC
Measurement circuit fault. Contact your local ABB representative.
A5EE Measurement circuit
DFF
Measurement circuit fault. Contact your local ABB representative.
A5EF PU state feedback State feedback from output
phases does not match control
signals.
Contact your local ABB representative.
A5F0 Charging feedback Charging feedback signal
missing.
Check the feedback signal coming from
the charging system.
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.
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.
0001 Slip frequency is too small. Check the settings of the motor
configuration parameters in groups 98
and 99.
Check that the drive is sized correctly
for the motor.
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.
