What to doCause
Event name /
Aux. code
Code
(hex)
Check the supply voltage.
If the problem persists, contact your
local ABB representative.
Check the supply voltage setting
(parameter 95.1 Supply voltage). Note
The voltage of the intermediate DC
circuit has not yet risen to operating
level.
DC not
charged
A3AA
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.
Check the settings of parameters
35.61 and 35.62.
Calculated motor cable temperature
has exceeded warning limit.
Motor cable
overload
A480
Check the dimensioning of the motor
cable in regard to required load.
Check the auxiliary code (format 0XYY
ZZZZ).
Problem with motor temperature

“X” identifies the affected
temperature monitoring function (1 =
parameter 35.11, 2 = parameter 35.21).
“YY” indicates the selected
temperature source, ie. the setting of
the selection parameter in
hexadecimal.
“ZZZZ” indicates the problem (see
actions for each code below).
Check parameters 35.11/35.21
against 91.21/91.24.
Sensor type mismatch.0001
Check parameters
35.11…35.14/35.21…35.24 (and
Temperature under limit.0002
91.21/91.24 if sensor is connected
to an encoder interface). Check the
sensor and its wiring.
Check parameters
35.11…35.14/35.21…35.24 (and
Short circuit.0003
91.21/91.24 if sensor is connected
to an encoder interface). Check the
sensor and its wiring.
Check parameters
35.11…35.14/35.21…35.24 (and
Open circuit.0004
91.21/91.24 if sensor is connected
to an encoder interface). Check the
sensor and its wiring.
Check the value of parameter 35.2
Measured temperature 1.
Measured temperature 1 has exceeded
warning limit.
External

A491
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of 35.13 Temperature
