Cause
The voltage of the intermediate DC
circuit has not yet risen to operating
level.
Calculated motor cable temperature
has exceeded warning limit.
Problem with motor temperature
measurement.
Sensor type mismatch.
Temperature under limit.
Short circuit.
Open circuit.
Measured temperature 1 has exceeded
warning limit.
What to do
Check the supply voltage.
If the problem persists, contact your
local ABB representative.
Check the supply voltage setting
(parameter 95.1 Supply
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.
Check the dimensioning of the motor
cable in regard to required load.
Check the auxiliary code (format 0XYY
ZZZZ).
"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

91.21/91.24 if sensor is connected
to an encoder interface). Check the
sensor and its wiring.
