Fault Message Table - Danfoss VLT Series Service Manual

FAULT MESSAGE TABLE

Table 1-3 lists the drive's fault messages and indicates whether
a warning, alarm, or a trip-locks occurs. After a trip-lock, input
power must be removed, the cause of the fault corrected,
and the input power restored to reset the drive.
No. Description
1 Under 10 volts (10 VOLT LOW)
2 Live zero fault (LIVE ZERO ERROR)
4 Input phase imbalance (MAINS IMBALANCE)
5 Voltage warning high (DC LINK VOLTAGE HIGH)
6 Voltage warning low (DC LINK VOLTAGE LOW)
7 Overvoltage (DC LINK OVERVOLT)
8 Undervoltage (DC LINK UNDERVOLT)
9 Inverter overloaded (INVERTER TIME)
10 Motor overloaded (MOTOR TIME)
11 Motor temp high (MOTOR THERMISTOR)
12 Current limit reached (CURRENT LIMIT)
13 Overcurrent (OVERCURRENT)
14 Ground fault detected (EARTH FAULT)
15 Switch mode power fault (SWITCH MODE FAULT)
16 Short circuit (CURR.SHORT CIRCUIT)
17 Serial communication timeout (STD BUSTIMEOUT)
18 HP field bus timeout (HPFB TIMEOUT)
19 Fault in EEPROM on power card (EE ERROR POWER)
20 Fault in EEPROM on control card (EE ERROR CONTROL)
22 Auto motor adaptation fault (AMA FAULT)
29 Heat-sink temperature high (HEAT SINK OVERTEMP.)
30 Motor phase U missing (MISSING MOT.PHASE U)
31 Motor phase V missing (MISSING MOT.PHASE V)
32 Motor phase W missing (MISSING MOT.PHASE W)
34 HPFB communication fault (HPFB COMM. FAULT)
35 Out of frequency range (OUT FREQ RNG/ROT LIM)
37 Inverter fault (GATE DRIVE FAULT)
39 Check parameters 104 and 106 (CHECK P.104 & P.106)
40 Check parameters 103 and 105 (CHECK P.103 & P.106)
41 Motor too large (MOTOR TOO BIG)
42 Motor too small (MOTOR TOO SMALL)
60 Safety stop (EXTERNAL FAULT)
61 Output frequency low (FOUT < FLOW)
62 Output frequency high (FOUT > FHIGH)
63 Output current low (I MOTOR < I LOW)
64 Output current high (I MOTOR > I HIGH)
65 Feedback low (FEEDBACK < FDB LOW)
66 Feedback high (FEEDBACK > FDB HIGH)
67 Reference low (REF. < REF. LOW)
68 Reference high (REF. > REF. HIGH)
69 Temperature auto derate (TEMP.AUTO DERATE)
99 Unknown fault (UNKNOWN ALARM)
Wherever an "X" is placed under both warning and alarm, a
warning precedes the alarm. An alarm always precedes, or
simultaneously accompanies, a trip-lock. Which faults are
reported may vary depending on the particular drive model.
