Check the auxiliary code (format 0XYY
ZZZZ).
Problem with motor temperature
measurement.
Incorrect
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
temperature 1
A491
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of 35.13 Temperature
1 warning limit.
Check the value of parameter 35.3
Measured temperature 2.
Measured temperature 2 has exceeded
warning limit.
External
temperature 2
A492
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of 35.23 Temperature
2 warning limit.
Check the cooling of the motor.The thermistor protection module
installed in slot 1 indicates
overtemperature.

A497
Check the motor load and drive
ratings.
Check the wiring of the temperature
sensor. Repair wiring if faulty.
Measure the resistance of the sensor.
Replace sensor if faulty.
Check the cooling of the motor.The thermistor protection module
installed in slot 2 indicates
overtemperature.
Motor
