Warnings and Alarms
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.
ALARM 56, Auto tune interrupted by user
The Auto tune has been interrupted by the user.
ALARM 57, Auto tune timeout
Try to restart Auto tune again. Repeated restarts may over
heat 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 the system can operate safely at a
higher limit.
WARNING 60, External interlock
A digital input signal is indicating a fault condition external
8 8
to the drive. An external interlock has commanded the
drive to trip. Clear the external fault condition. To resume
normal operation, apply 24V DC to the terminal
programmed for external interlock. Reset the drive.
WARNING/ALARM 61, Feedback error
An error has been detected between calculated speed and
speed measurement from feedback device. The function
Warning/Alarm/Disabling setting is in H-20 Motor Feedback
Loss Function. Accepted error setting in H-21 Motor
Feedback Speed Error and the allowed time the error occur
setting in H-22 Motor Feedback Loss Timeout. During a
commissioning procedure the function may be effective.
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.
ALARM 63, Mechanical brake low
The actual motor current has not exceeded the "release
brake" current within the "Start delay" time window.
WARNING/ALARM 65, Control card over temperature
The cutout 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.

AF-650 GP Operating Instructions
WARNING 66, Heatsink temperature low
The 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 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.
ALARM 69, Power card temperaturePower card
temperature
The temperature sensor on the power card is either too
hot or too cold.
Troubleshooting
ALARM 70, Illegal drive configuration
The control card and power card are incompatible. Contact
your supplier with the model number of the unit from the
nameplate and the part numbers of the cards to check
compatibility.
WARNING 76, Power unit setup
The required number of power units does not match the
detected number of active power units.
77 WARNING, Reduced power mode
This warning indicates that the drive is operating in
reduced power mode (i.e. less than the allowed number of
inverter sections). This warning will be generated on power
cycle when the drive is set to run with fewer inverters and
will remain on.
ALARM 78, Tracking error
The difference between set point value and actual value
has exceeded the value in H-25 Tracking Error. Disable the
function by H-24 Tracking Error Function or select an alarm/
warning also in H-24 Tracking Error Function. Investigate the
mechanics around the load and motor, Check feedback
connections from motor – encoder – to drive. Select motor
feedback function in H-20 Motor Feedback Loss Function.
Adjust tracking error band in H-25 Tracking Error and
H-27 Tracking Error Ramping.
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Unit Restored to Factory Settings
Parameter settings are restored to factory settings after a
manual reset. Reset the unit to clear the alarm.
Check that the ambient operating temperature is
within limits.
Check for clogged filters.
Check fan operation.
Check the power card.
