ALARM 51, Auto tune check Unom and Inom
The setting of motor voltage, motor current, and motor power is presumably wrong. Check the settings.
ALARM 52, Auto tune low Inom
The motor current is too low. Check the settings.
ALARM 53, Auto tune motor too big
The motor is too big for the Auto tune to be carried out.
ALARM 54, Auto tune motor too small
The motor is too big 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 time-out
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
resistances 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 par. F-43 Current Limit.
WARNING 60, External interlock
External interlock has been activated. To resume normal operation, apply 24 VDC to the terminal programmed for external interlock and reset the frequency
converter (via serial communication, digital I/O, or by pressing the 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 overtemperature
Control card overtemperature: 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. See the ratings table in Section 1.9 for the temperature reading that will trigger this warning.
Troubleshooting:
The heatsink temperature measured as 0 ° C could indicate that the temperature 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 (see section 6.2.8).
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 24 VDC to terminal 37, then send a reset signal (via bus, digital I/O, or by pressing the reset key.
See par. 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. 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.
