FIELDBUS COMM
Programmable
fault: 50.02 COMM
LOSS FUNC
Cyclical communication
between the drive and
fieldbus adapter module or
between PLC and fieldbus
adapter module is lost.
Check the status of fieldbus
communication. See the
appropriate fieldbus adapter
module User’s manual.
Check fieldbus parameter settings.
See parameter group 50
FIELDBUS on page 251.
Check cable connections.
Check if the communication master
can communicate.

MOTOR
OVERTEMP
Programmable
fault: 46.07 MOT
TEMP PROT
Measured motor
temperature has exceeded
the fault limit defined with
parameter 46.10 MOT
TEMP FLT LIM.
Check that the actual number of
sensors corresponds to the value
set with parameter 46.08 MOT
TEMP SOURCE.
Check motor ratings and load.
Let the motor cool down. Ensure
proper motor cooling: Check the
cooling fan, clean cooling surfaces,
etc.
Check the value of the fault limit.

AI SUPERVISION
Programmable
fault: 13.12 AI
SUPERVISION
Analogue input AI1 or AI2
signal has reached the limit
defined with parameter
13.13 AI SUPERVIS ACT.
Check the analogue input AI1/2
source and connections.
Check analogue input AI1/2
minimum and maximum limit
settings, parameters 13.02 and
13.03 / 13.07 and 13.08.

Programmable
fault: 90.05 ENC
CABLE FAULT
Encoder cable fault
detected.
Check the cable between FEN-xx
interface and encoder. After any
modifications in cabling, re-
configure the interface by switching
the drive power off and on, or by
activating parameter 90.06 ENC
