A591 Drive HW initialization. Drive hardware setup is
initializing.
1 - Initializing HW settings for
the first time.
See auxiliary code.
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 109).
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.
A5F1 Redundant
measurement
Duplicated measurements are
beyond limits.
Contact your local ABB representative.
A5F2 Overtemperature hw Excessive hardware
temperature.
Contact your local ABB representative.
A682 Flash erase speed 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 Parameter
save manually 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.
