Warnings and Alarms
WARNING 49, Speed limit
When the speed is not within the specified range in F-18
and F-17, the frequency converter shows a warning. When
the speed is below the specified limit in H-36 Trip Speed
Low [RPM] (except when starting or stopping), the
frequency converter trips.
ALARM 50, Auto tune calibration failed
Contact your GE supplier or GE Service Department.
ALARM 51, Auto tune check U
The settings for motor voltage, motor current and motor
power are wrong. Check the settings in parameters P-02,
P-03, P-06, P-07, F-04 and F-05.
ALARM 52, Auto tune low I
nom
The motor current is too low. Check the settings.
ALARM 53, Auto tune motor too big
The motor is too big for the Auto tune to operate.
ALARM 54, Auto tune motor too small
The motor is too small for the Auto tune to operate.
ALARM 55, Auto tune parameter out of range
The parameter values of the motor are outside of the
acceptable range. Auto tune cannot run.
ALARM 56, Auto tune interrupted by user
The user has interrupted the Auto tune.
ALARM 57, Auto tune internal fault
Try to restart Auto tune again. Repeated restarts can over
heat the motor.
ALARM 58, Internal fault
Contact your GE supplier.
WARNING 59, Current limit
The current is higher than the value in F-43 Current Limit.
Ensure that Motor data in parameters P-02, P-03, P-06,
P-07, F-04 and F-05 are set correctly. Possibly increase the
current limit. Be sure that the system can operate safely at
a higher limit.
WARNING 60, External interlock
A digital input signal is indicating a fault condition external
to the frequency converter. An external interlock has
commanded the frequency converter to trip. Clear the
external fault condition. To resume normal operation,
apply 24 V DC to the terminal programmed for external
interlock. Reset the frequency converter.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
F-03 Max Output Frequency 1. Check the application to
determine the cause. Possibly increase the output
frequency limit. Be sure the system can operate safely at a
higher output frequency. The warning will clear when the
output drops below the maximum limit.
WARNING/ALARM 65, Control card over temperature
The cut-out temperature of the control card is 80 °C.

Troubleshooting
•
Check that the ambient operating temperature is
within limits
•
Check for clogged filters
•
Check fan operation
•
Check the control card
WARNING 66, Heatsink temperature low
The frequency converter is too cold to operate. This
warning is based on the temperature sensor in the IGBT
module.
Increase the ambient temperature of the unit. Also, a
trickle amount of current can be supplied to the frequency
converter whenever the motor is stopped by setting
B-00 DC Hold Current at 5% and H-80 Function at Stop
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down. Check that the configuration
change is intentional and reset the unit.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
Troubleshooting
Check that the ambient operating temperature is
within limits.
Check for clogged filters.
Check fan operation.
Check the power card.
ALARM 70, Illegal drive configuration
The control card and power card are incompatible. To
check compatibility, contact your supplier with the model
number of the unit from the nameplate and the part
numbers of the cards.
ALARM 80, Drive initialised to default value
Parameter settings are restored to factory settings after a
manual reset. To clear the alarm, reset the unit.
ALARM 92, No flow
A no-flow condition has been detected in the system.
AP-23 No-Flow Function is set for alarm. Troubleshoot the
system and reset the frequency converter after the fault
has been cleared.
ALARM 93, Dry pump
A no-flow condition in the system with the frequency
converter operating at high speed may indicate a dry
pump. AP-26 Dry Pump Function is set for alarm.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
ALARM 94, End of curve
Feedback is lower than the set point. This may indicate
leakage in the system. AP-50 End of Curve Function is set
for alarm. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
