Warnings and Alarms
Troubleshooting
Check for proper grounding and loose
connections.
Check for proper wire size.
Check motor cables for short-circuits or leakage
currents.
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24 V, 5 V,
±18 V. When powered with three phase AC line voltage, all
three supplies are monitored.
Troubleshooting
Check for a defective power card.
Check for a defective control card.
Check for a defective option card.
If a 24 V DC power supply is used, verify proper
supply power.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. The external
24 V DC backup power supply may be overloaded,
otherwise contact the GE supplier.

WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card. Check for a defective control card. If an
option card is present, check for an overvoltage condition.
WARNING 49, Speed limit
When the speed is not within the specified range in F-18
and F-17, the adjustable frequency drive shows a warning.
When the speed is below the specified limit in H-36 Trip
Speed Low [RPM] (except when starting or stopping), the
adjustable frequency drive will trip.
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
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 will not run.

56 ALARM, 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
overheat the motor.
ALARM 58, Auto Tune 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 adjustable frequency drive. An external interlock has
commanded the adjustable frequency drive to trip. Clear
the external fault condition. To resume normal operation,
apply 24 V DC to the terminal programmed for external
interlock. Reset the adjustable frequency drive.
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 cutout temperature of the control card is 176° F
[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 adjustable frequency drive 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 adjustable
frequency drive 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.
