A591 Drive HW initialization Initialization of the drive
hardware.
Check the auxiliary code. See actions for
each code below.
0000 Drive hardware setup is

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 261).
Check the value of parameter 95.04
Control board supply.
A5EA Measurement circuit

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

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.
A684 Power fail saving Power fail saving warning. Contact your local ABB representative.
