1.6 Troubleshooting
No. Description Warning Alarm Trip
Lock
Error Cause of Problem
2 Live zero error X X Signal on terminal 53 or 60 is less than 50% of value set in
6-10 Terminal 53 Low Voltage, 6-12 Terminal 53 Low Currentand
6-22 Terminal 54 Low Current.
4
Mains phase loss
1)
X X X Missing phase on supply side, or too high voltage imbalance. Check
supply voltage.
7
DC over voltage
1)
X X Intermediate circuit voltage exceeds limit.
8
DC under voltage
1)
X X Intermediate circuit voltage drops below “voltage warning low” limit.
9 Inverter overloaded X X More than 100% load for too long.
10 Motor ETR over temperature X X Motor is too hot due to more than 100% load for too long.
11 Motor thermistor over
temperature
X X Thermistor or thermistor connection is disconnected.
12 Torque limit X Torque exceeds value set in either par. 4-16 or 4-17.
13 Over Current X X X Inverter peak current limit is exceeded.
14 Earth fault X X X Discharge from output phases to ground.
16 Short Circuit X X Short-circuit in motor or on motor terminals.
17 Control word timeout X X No communication to frequency converter.
25 Brake resistor short-circuited X X Brake resistor is short-circuited, thus brake function is disconnected.
27 Brake chopper short-circuited X X Brake transistor is short-circuited, thus brake function is discon-
nected.
28 Brake check X Brake resistor is not connected/working
29 Power board over temp X X X Heat-sink cut-out temperature has been reached.
30 Motor phase U missing X X Motor phase U is missing. Check the phase.
31 Motor phase V missing X X Motor phase V is missing. Check the phase.
32 Motor phase W missing X X Motor phase W is missing. Check the phase.
38 Internal fault X X Contact local Danfoss supplier.
44 Earth fault X X Discharge from output phases to ground.
47 Control Voltage Fault X X 24 V DC may be overloaded.
51 AMT check U
nom
and I
nom
X Wrong setting for motor voltage and/or motor current.
52 AMT low I
nom
X Motor current is too low. Check settings.
59 Current limit X VLT overload.
63 Mechanical Brake Low X Actual motor current has not exceeded “release brake” current
within “start delay” time window.
80 Drive Initialised to Default Value X All parameter settings are initialized to default settings.
84 The connection between drive
and is lost
X No communication between and frequency converter
85 Button disabled X
See parameter group 0-4* LCP
86 Copy fail X An error occurred while copying from frequency converter to LCP or
vice versa.
87 data invalid X Occurs when copying from LCP if the LCP contains erroneous data -
or if no data was uploaded to the LCP.
88 data not compatible X Occurs when copying from LCP if data are moved between
frequency converters with major differences in software versions.
89 Parameter read only X Occurs when trying to write to a read-only parameter.
90 Parameter database busy X LCP and RS485 connection are trying to update parameters simulta-
neously.
91 Parameter value is not valid in this
mode
X Occurs when trying to write an illegal value to a parameter.
92 Parameter value exceeds the
min/max limits
X Occurs when trying to set a value outside the range.
nw
run
Not While RUNning X Parameter can only be changed when the motor is stopped.
Err. A wrong password was entered X Occurs when using a wrong password for changing a password-
protected parameter.
1)
These faults may be caused by mains distortions. Installing Danfoss Line Filter may rectify this problem.
