58 ACH580 Installation, Operation and Maintenance Manual
ACH580-01 Installation
A2B4 Short circuit Short-circuit in motor
cable(s) or motor.
Check motor and motor cable for
cabling errors.
Check motor and motor cable
(including phasing and delta/star
connection).
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable. See Checking the
insulation of the assembly on
page 16 .
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
A2BA IGBT overload Excessive IGBT
junction to case
temperature. This
warning protects the
IGBT(s) and can be
activated by a short
circuit in the motor
cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A3A1 DC link overvoltage Intermediate circuit DC
voltage too high (when
the drive is stopped).
Check the supply voltage setting
(parameter 95.01 Supply voltage ).
Note that the wrong setting of the
parameter may cause the motor to
rush uncontrollably, or may overload
the brake chopper or resistor.
Check the supply voltage.
If the problem persists, contact your
local ABB representative.
A3A2 DC link undervoltage Intermediate circuit DC
voltage too low (when
the drive is stopped).
A3AA DC not charged The voltage of the
intermediate DC circuit
has not yet risen to
operating level.
A490 Incorrect temperature
sensor setup
Temperature cannot be
supervised due to
incorrect adapter setup.
Check the settings of temperature
source parameters 35.11 and 35.21 .
A491 External temperature 1
(Editable message text) Measured temperature
1 has exceeded
warning limit.
Check the value of parameter 35.02
Measured temperature 1 .
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of
35.13 Temperature
1 warning limit .
A492 External temperature 2
(Editable message text) Measured temperature
2 has exceeded
warning limit.
Check the value of parameter 35.03
Measured temperature 2 .
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of
35.23 Temperature
2 warning limit .
A4A0 Control board temperature Control board
temperature is too high.
Check the auxiliary code. See actions
for each code below.
