GE AF-650 GP Operating Instructions Manual page 59

ALARM 54, Auto Tune motor too small:
The motor is too small for the Auto Tune to be carried out.
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
4
not critical.
ALARM 58, Auto Tune internal fault:
Contact the local GE supplier.
WARNING 59, Current limit:
The current is higher than the value in par. F-43 Current 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 fre-
quency converter (via serial communication, digital I/O, or by pressing reset
button on keypad).
WARNING 61, Tracking error
An error has been detected between the calculated motor speed and the
speed measurement from the feedback device. The function for Warning/
Alarm/ Disable is set in par. H-20 Motor Feedback Loss Function, error setting
in par. H-21 Motor Feedback Speed Error, and the allowed error time in
par. 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 par. F-03 Max Output
Frequency 1
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 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 cut-out 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. See
section Ratings tables for the temperature reading that will trigger this warn-
ing.
Troubleshooting:
The heatsink temperature measured as 0° C could indicate that the temper-
ature sensor is defective, thereby causing the fan speed to increase to the
maximum. If the sensor wire between the IGBT and the gate drive card is
disconnected, this warning is produced. Also, check the IGBT thermal sensor.
ALARM 67, Option Configuration has Changed:
One or more options has 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 24 V DC to
terminal 37, then send a reset signal (via Bus, Digital I/O, or by pressing [RE-
SET]). For correct and safe use of the Safe Stop function follow the related
information and instructions in the Design Guide
ALARM 69, Power card temperature
The temperature sensor on the power card is either too hot or too cold. See
the ratings table in Section 1.9 for the high and low temperatures that can
cause this alarm.
Troubleshooting:
Check the operation of the door fans. Make sure that the filters for the door
fans are not blocked. Make sure that the gland plate is properly installed on
IP21 and IP54 (NEMA 1 and NEMA 12) frequency converters.
ALARM 70, Illegal Frequency Configuration:
Actual combination of control board and power board is illegal.
Warning 73, Safe stop auto restart:
Safe stopped. Note that with automatic restart enabled, the motor may start
when the fault is cleared.
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 gen-
erated 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 par. H-25 Tracking Error. Disable the function by par. H-24 Tracking
Error Function or select an alarm/warning also in par. H-24 Tracking Error
Function. Investigate the mechanics around the load and motor, Check feed-
back connections from motor – encoder – to drive. Select motor feedback
function in par. H-20 Motor Feedback Loss Function. Adjust tracking error band
in par. H-25 Tracking Error and par. H-27 Tracking Error Ramping.
ALARM 79, Illegal power section configuration:
The scaling card is the incorrect part number or not installed. Also, the MK102
connector on the power card is not installed.
ALARM 80, Restore to Default Value:
Parameter settings are restored to default setting after a manual (three-fin-
ger) reset.
WARNING 81, CSIV corrupt:
CSIV file has syntax errors.
WARNING 82, CSIV parameter error:
CSIV has failed to record a parameter.
ALARM 91, Analog input 54 wrong settings:
Switch S202 must be set in the position OFF (voltage input) when a KTY sensor
is connected to analog input terminal 54.
ALARM 92, No flow:
A no-load situation has been detected in the system. See parameter group
AP-2#.
