Error Cause of Problem
2 Live zero error X X Signal on terminal 53 or 60 is less than 50% of value set in par. 6-10,
6-12 and 6-22.
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 Driveoverloaded X X More than 100% load for too long.
10 Motor Electronic Overload 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 Drive current limit is exceeded.
14 Earth fault 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 disconnec-
ted.
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 GE 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 Auto Tune check U
nom
and I
nom
X Wrong setting for motor voltage and/or motor current.
52 Auto Tune low I
nom
X Motor current is too low. Check settings.
59 Current limit X Drive overload.
63 Mechanical Brake Low X Actual motor current has not exceeded “release brake” current within
“start delay” time window.
80 Drive restored to Factory Settings X All parameter settings are restored to factory default settings.
84 The connection between drive and
Keypad is lost X No communication between Keypad and frequency converter
85 Button disabled X See parameter group 0-4* Keypad
86 Copy fail X An error occurred while copying from frequency converter to
Keypad or vice versa.
87 Keypad data invalid X Occurs when copying from Keypad if the Keypad contains erroneous
data - or if no data was uploaded to the Keypad.
88 Keypad data not compatible X Occurs when copying from Keypad if data are moved between fre-
quency 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 Keypad and RS485 connection are trying to update parameters si-
multaneously.
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-pro-
tected parameter.
1) These faults may be caused by mains distortions. Installing GE Line Filter may rectify this problem.
