Warnings and Alarms
WARNING/ALARM 13, Over current
The inverter peak current limit (approx. 200% of the rated
current) is exceeded. The warning lasts about 1.5 sec., then
the frequency converter trips and issues an alarm. If
extended mechanical brake control is selected, trip can be
reset externally.
Troubleshooting:
This fault may be caused by shock loading or fast
acceleration with high inertia loads.
Turn off the frequency converter. Check if the
motor shaft can be turned.
Check that the motor size matches the frequency
converter.
Incorrect motor data in parameters P-02, P-03,
P-06, P-07, F-04 and F-05.
ALARM 14, Earth (ground) fault
There is a discharge from the output phases to earth,
either in the cable between the frequency converter and
the motor or in the motor itself.
8 8
Troubleshooting:
Turn off the frequency converter and remove the
earth fault.
Measure the resistance to ground of the motor
leads and the motor with a megohmmeter to
check for earth faults in the motor.
Perform current sensor test.
ALARM 15, Hardware mismatch
A fitted option is not operational with the present control
board hardware or software.
Record the value of the following parameters and contact
your GE supplier:
ID-40 Drive Type
ID-41 Power Section
ID-42 Voltage
ID-43 Software Version
ID-45 Actual Typecode String
ID-49 SW ID Control Card
ID-50 SW ID Power Card
ID-60 Option Mounted
ID-61 Option SW Version
ALARM 16, Short circuit
There is short-circuiting in the motor or on the motor
terminals.
Turn off the frequency converter and remove the short-
circuit.

AF-600 FP High Power Operating Instructions
WARNING/ALARM 17, Control word timeout
There is no communication to the frequency converter.
The warning will only be active when O-04 Control Word
Timeout Function is NOT set to OFF.
If O-04 Control Word Timeout Function is set to Stop and
Trip, a warning appears and the frequency converter decels
until it trips, while giving an alarm.
Troubleshooting:
ALARM 18, Start failed
The speed has not been able to exceed AP-70 Compressor
Start Max Speed [RPM] during start within the allowed time.
(set in AP-72 Compressor Start Max Time to Trip).
This may be caused by a blocked motor.
WARNING 23, Internal fan fault
The fan warning function is an extra protection function
that checks if the fan is running / mounted. The fan
warning can be disabled in SP-53 Fan Monitor ([0]
Disabled).
For the 4x, 5x, and 6x unit size drives, the regulated
voltage to the fans is monitored.
Troubleshooting:
WARNING 24, External fan fault
The fan warning function is an extra protection function
that checks if the fan is running / mounted. The fan
warning can be disabled in SP-53 Fan Monitor ([0]
Disabled).
For the 4x, 5x, and 6x unit size drives, the regulated
voltage to the fans is monitored.
Troubleshooting:
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not be reset until the
temperature falls below a defined heatsink temperature.
The trip and reset point are different based on the drive
power size.
Check connections on the serial communication
cable.
Increase O-03 Control Word Timeout Time
Check operation of the communication
equipment.
Verify proper installation based on EMC
requirements.
Check fan resistance.
Check soft charge fuses.
Check fan resistance.
Check soft charge fuses.
