Troubleshooting
ALARM 51, Auto tune check U
The settings for motor voltage, motor current, and motor
power are wrong.
Troubleshooting
•
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.
Troubleshooting
•
Check the settings in parameter P-03 Motor
Current.

ALARM 53, Auto tune motor too big
The motor is too large 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
Auto tune cannot run because the parameter values of the
motor are outside of the acceptable range.
ALARM 56, Auto tune interrupted by user
The AMA is manually interrupted.
ALARM 57, Auto tune internal fault
Try to restart Auto tune. Repeated restarts can overheat
the motor.
ALARM 58, Internal fault
Contact the GE supplier.
WARNING 59, Current limit
The current is higher than the value in
parameter F-43 Current Limit. Ensure that motor data in
parameters P-02, P-03, P-06, P-07, F-04, and F-05 is set
correctly. Increase the current limit if necessary. Ensure that
the system can operate safely at a higher limit.
WARNING 60, External interlock
A digital input signal indicates 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,
and reset the frequency converter.
WARNING/ALARM 61, Feedback error
An error has been detected between calculated speed and
speed measurement from feedback device.
Troubleshooting
•
Check the settings for warning/alarm/disabling in
parameter H-20 Motor Feedback Loss Function.
•
Set the tolerable error in parameter H-21 Motor
Feedback Speed Error.
•
Set the tolerable feedback loss time in
parameter H-22 Motor Feedback Loss Timeout.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
parameter F-03 Max Output Frequency 1. Check the
application for possible causes. Possibly increase the

output frequency limit. Be sure that the system can
operate safely at a higher output frequency. The warning
clears 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 64, Voltage limit
The combination of load and speed requires a motor
voltage higher than what can be provided due to the
actual DC-link voltage.
WARNING/ALARM 65, Control card over temperature
The cut-out temperature of the control card is 85 °C.
Troubleshooting
•
Check that the ambient operating temperature is
within the limits.
•
Check for clogged filters.
•
Check the 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 parameter B-00 DC Hold Current to 5% and
parameter 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 68, Safe Stop activated
Safe Torque Off (STO) has been activated. To resume
normal operation, apply 24 V DC to terminal 37, then send
a reset signal (via bus, digital I/O, or by pressing [Reset]).
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 the GE supplier with the
model number from the unit nameplate and the part
numbers of the cards.
