336 Fault tracing
A4B0 Excess temperature Power unit module
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A4B1 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
A4F6 IGBT temperature Drive IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A580 PU communication Communication errors
detected between the drive
control unit and the power unit.
Check the connections between the drive
control unit and the power unit.
A591 Drive HW initialization Initialization of the drive
hardware.
Check the auxiliary code. See actions for
each code below.
0000 Drive hardware setup is
initializing.
Wait for the setup to initialize.
0001 Initializing HW settings for the
first time.
Wait for the setup to initialize.
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 209).
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.
A5EC PU communication
internal
Communication errors
detected between the drive
control unit and the power unit.
Check the connections between the drive
control unit and the power unit.
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.
A686 Checksum mismatch
Programmable warning:
96.54 Checksum action
The calculated parameter
checksum does not match any
enabled reference checksum.
Check that all necessary approved
(reference) checksums (96.71…96.72)
are enabled in 96.55 Checksum control
word.
Check the parameter configuration.
Using 96.55 Checksum control word,
enable a checksum parameter and copy
the actual checksum into that parameter.
