Warnings and Alarms
ALARM 55, Auto tune parameter out of range
The parameter values found from the motor are outside
acceptable range.
ALARM 56, Auto tune interrupted by user
The Auto tune has been interrupted by the user.
ALARM 57, Auto tune timeout
Try to start the Auto tune again a number of times, until
the Auto tune is carried out. Please 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.
WARNING 60, External interlock
External interlock has been activated. To resume normal
operation, apply 24V DC to the terminal programmed for
external interlock and reset the drive (via serial communi-
cation, digital I/O, or by pressing reset button on keypad).
WARNING 61, Tracking error
An error has been detected between calculated motor
speed and speed measurement from feedback device. The
function for Warning/Alarm/Disable is set in H-20 Motor
Feedback Loss Function, error setting in H-21 Motor
Feedback Speed Error, and the allowed error time 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
WARNING 64, Voltage limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control card over temperature
Control card over temperature: The cutout temperature of
the control card is 80° C.
WARNING 66, Heatsink temperature low
This warning is based on the temperature sensor in the
IGBT module.
Troubleshooting:
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down.
ALARM 68, Safe stop activated
Safe stop has been activated. To resume normal operation,
apply 24V DC to terminal 37, then send a reset signal (via
Bus, Digital I/O, or by pressing the reset key. See
E-07 Terminal 37 Safe Stop.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
AF-650 GP High Power Operating Instructions
Troubleshooting:
ALARM 70, Illegal Drive Configuration
Actual combination of control board and power board is
illegal.
WARNING 76, Power Unit Setup
The required number of power units does not match the
detected number of active power units.
Troubleshooting:
When replacing a unit size 6X module this will occur if the
power specific data in the module power card does not
match the rest of the drive. Please confirm the spare part
and its power card are the correct part number.
WARNING 77, 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 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 Restored to Factory Settings
Parameter settings are restored to factory settings after a
manual reset.
ALARM 91, Analog input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analog input terminal
54.
ALARM 243, Brake IGBT
This alarm is only for unit sizes 6X. It is equivalent to Alarm
27. The report value in the alarm log indicates which
power module generated the alarm:
ALARM 244, Heatsink temperature
This alarm is only for unit sizes 6X. It is equivalent to Alarm
29. The report value in the alarm log indicates which
power module generated the alarm:
Check the operation of the door fans.
Check that the filters for the door fans are not
blocked.
Check that the gland plate is properly installed
on IP 21 and IP 54 (NEMA 1 and NEMA 12) drives.
1 = left most inverter module.
2 = middle inverter module in unit sizes 62 or 64.
2 = right inverter module in unit sizes 61 or 63.
3 = right inverter module in unit sizes 62 or 64.
5 = rectifier module.
1 = left most inverter module.
2 = middle inverter module in unit sizes 62 or 64.
2 = right inverter module in unit sizes 61 or 63.
