Cause
Estimated motor temperature
(based on motor thermal model)
has exceeded fault limit defined
45.01
by parameter 45.04 MOT TEMP
FLT LIM.
Measured motor temperature
has exceeded fault limit defined
by parameter 45.04 MOT TEMP
FLT LIM.
Broken wire in the temperature
sensor.
Selected operation mode
requires position feedback data
(actual position), but no
feedback data is available.
Analogue input AI1 or AI2 signal
has reached limit defined by
parameter 13.13 AI SUPERVIS
13.12
ACT.
Encoder 1 cable fault detected.
90.05
Encoder 2 cable fault detected.

Configuration of the drive-to-
drive link has failed for a reason
other than those indicated by
alarm 2042, for example start
inhibition is requested but not
granted.
What to do
Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
Check value of fault limit.
Check motor thermal model settings,
parameters 45.06...45.08
THERM TIME.
Check that actual number of sensors
corresponds to value set by parameter
MOT TEMP SOURCE.
Check motor ratings and load.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
Check value of fault limit.
Check the temperature sensor connection.
Check actual position source setting,
POS ACT SEL.
Check encoder installation. See ENCODER1
fault description for more information.
(The used operation mode is indicated by
signal 6.12 OP MODE ACK.)
Check analogue input AI1/2 source and
connections.
Check analogue input AI1/2 minimum and
maximum limit settings, parameters
and 13.03 / 13.07 and 13.08.
Check cable between FEN-xx interface and
encoder 1. After any modifications in cabling,
re-configure interface by switching drive
power off and on, or by activating parameter
90.10 ENC PAR REFRESH.
Check cable between FEN-xx interface and
encoder 2. After any modifications in cabling,
re-configure interface by switching drive
power off and on, or by activating parameter
90.10 ENC PAR REFRESH.
