6 Troubleshooting
6.1 Warning and Alarm Messages
No. Description W A T Cause of Problem
2 Live zero error (LIVE ZERO ERROR) X X X Voltage or current signal on terminals 53 or 60 is below 50% of preset
value.
4 Mains phase loss (MAINS PHASE LOSS) X X X No phase on mains supply side.
5 Voltage warning high (DC LINK VOLTAGE
HIGH) X The intermediate circuit voltage exceeds the limit set.
6 Voltage warning low (DC LINK VOLTAGE
LOW) X The intermediate circuit voltage is lower the limit set.
7 Overvoltage (DC LINK OVERVOLT) X X X The intermediate voltage exceeds the limit set.
8 Undervoltage (DC LINK UNDERVOLT) X X X The intermediate voltage is lower than the limit set.
9 Inverter overload (INVERTER TIME) X X The frequency converter is close to tripping due to overload.
10 Motor overloaded ( MOTOR, TIME) X X The motor is too hot due to overload.
11 Motor thermistor (MOTOR THERMISTOR) X X Either the motor is too hot or the thermistor has been disconnected.
12 Current limit (CURRENT LIMIT) X X Output current is higher than set in par. 221.
13 Overcurrent (OVERCURRENT) X X X The peak current limit has been exceeded.
14 Earth fault (EARTH FAULT) X X Discharge from output phases to earth.
15 Switch mode fault (SWITCH MODE
FAULT) X X Fault in switch mode power supply.
16 Short-circuit (CURR. SHORT CIRCUIT) X X Short-circuit on the motor terminals or in the motor.
17 Serial communication timeout (STD BUS
TIMEOUT) X X No serial communication to the frequency converter.
18 HPFB bus timeout (HPFB TIMEOUT) X X No serial communication to the communication option card.
33 Out of frequency range (OUT FREQ
RNG/ROT LIM) X Output frequency has reached the limit set in either par. 201 or par.
202.
34 HPFB communication fault (PROFIBUS
OPT. FAULT) X X Fault only occurs in fieldbus versions. Please see par. 953 in fieldbus
literature.
35 Inrush fault (INRUSH FAULT) X X Connected to mains too many times within 1 minute.
36 Overtemperature (OVERTEMPERATURE) X X The upper temperature limit has been exceeded.
37-45 Internal fault (INTERNAL FAULT) X X Contact Danfoss.
50 AMT not possible X Either R
S
value is outside permitted limits, or motor current is too low
on at least one phase, or the motor is too small for AMA.
51 AMT fault re. nameplate data (AMT
TYPE.DATA FAULT) X Inconsistency between registered motor data.
54 AMT wrong motor (AMT WRONG
MOTOR) X AMA has detected a missing motor phase.
55 AMT timeout (AMT TIMEOUT) X Calculations are taking too long, probably caused by noise on motor
cables.
56 AMT warning during AMT (AMT WARN.
DURING AMT) X Warning is given while AMA is performed.
99 Locked (LOCKED) X See parameter 018 Lock for data changes .
