0047 MOTOR OVERTEMP
(0x4310)
Programmable fault: 45.01
MOT TEMP PROT
Estimated motor temperature
(based on motor thermal model)
has exceeded fault limit defined
by parameter 45.04 MOT TEMP
FLT LIM.
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 and 45.10 MOT
THERM TIME.
Measured motor temperature
has exceeded fault limit defined
by parameter 45.04 MOT TEMP
FLT LIM.
Check that actual number of sensors
corresponds to value set by parameter 45.02
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.
0048 POS ACT MEAS
(0x8584)
Selected operation mode
requires position feedback data
(actual position), but no
feedback data is available.
Check actual position source setting, 60.01
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.)
0049 AI SUPERVISION
(0x8110)
Programmable fault: 13.12
AI SUPERVISION
Analogue input AI1 or AI2 signal
has reached limit defined by
parameter 13.13 AI SUPERVIS
ACT.
Check 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.
0050 ENCODER 1 CABLE
(0x7389)
Programmable fault: 90.05
ENC CABLE FAULT
Encoder 1 cable fault detected. 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.
0051 ENCODER 2 CABLE
(0x738A)
Programmable fault: 90.05
ENC CABLE FAULT
Encoder 2 cable fault detected. 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.
0052 D2D CONFIG
(0x7583)
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.
