Warnings and Alarms
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 a number of times until the
Auto tune is carried out. Note that repeated runs may heat
the motor to a level where the resistance Rs and Rr are
increased. In most cases, however, this is not critical.
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
External interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
external interlock and reset the adjustable frequency drive
(via serial communication, digital I/O, or by pressing
[Reset]).
WARNING/ALARM 61, Tracking error
An error has been detected between the calculated motor
speed and the speed measurement from the feedback
device. The function Warning/Alarm/Disable is set 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 is higher than the value set in
F-03 Max Output Frequency 1.
ALARM 64, Voltage Limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
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.
TM
AF-650 GP Design and Installation Guide
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
Troubleshooting
The heatsink temperature measured as 32° F [0°C] could
indicate that the temperature sensor is defective, causing
the fan speed to increase to the maximum. If the sensor
wire between the IGBT and the gate drive card is discon-
nected, this warning would result. Also, check the IGBT
thermal sensor.
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
ALARM 70, Illegal adjustable frequency 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 set-up
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 adjustable frequency 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 adjustable frequency
drive is set to run with fewer inverters and will remain on.
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, Drive initialized to default value
Parameter settings are restored to factory settings after a
manual reset. Reset the unit to clear the alarm.
WARNING/ALARM 104, Mixing fan fault
The fan monitor checks that the fan is spinning at power-
up or whenever the mixing fan is turned on. If the fan is
not operating, then the fault is annunciated. The mixing-
DET-767A
Check the operation of the door fans.
Make sure that the filters for the door fans are
not blocked.
Check that the connector plate is properly
installed on IP21/IP 54 (NEMA 1/12) adjustable
frequency drives.
