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:
Par. ID-40 Drive Type
Par. ID-41 Power Section
Par. ID-42 Voltage
Par. ID-43 Software Version
Par. ID-45 Actual Typecode String
Par. ID-49 SW ID Control Card
Par. ID-50 SW ID Power Card
Par. ID-60 Option Mounted
Par. 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.
WARNING/ALARM 17, Control word timeout
There is no communication to the frequency converter.
The warning will only be active when par. O-04 Control Word Timeout Func-
tion is NOT set to OFF.
If par. 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:
Check connections on the serial communication cable.
Increase par. O-03 Control Word Timeout Time
Check operation of the communication equipment.
Verify proper installation based on EMC requirements.
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 par. SP-53 Fan
Monitor ([0] Disabled).
For the 4x, 5x, and 6x unit size drives, the regulated voltage to the fans is
monitored.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
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 par. SP-53 Fan
Monitor ([0] Disabled).
For the 4x, 5x, and 6x unit size drives, the regulated voltage to the fans is
monitored.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been exceeded. The temper-
ature 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.
Troubleshooting:
Ambient temperature too high.
Too long motor cable.
Incorrect clearance above and below the drive.
Dirty heatsink.
Blocked air flow around the drive.
Damaged heatsink fan.
For the 4x, 5x, and 6x unit size Drives, this alarm is based on the temperature
measured by the heatsink sensor mounted inside the IGBT modules. For the
6x unit size drives, this alarm can also be caused by the thermal sensor in the
Rectifier module.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
IGBT thermal sensor.
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the motor is missing.
Turn off the frequency converter and check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the frequency converter and the motor is missing.
Turn off the frequency converter and check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and the motor is missing.
Turn off the frequency converter and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time period. Let unit cool
to operating temperature.
WARNING/ALARM 34, Network communication fault
The network on the communication option card is not working.
WARNING/ALARM 35, Out of frequency range:
This warning is active if the output frequency has reached the high limit (set
in par. H-73) or low limit (set in par. H-72).
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to the frequency con-
verter is lost and par. SP-10 Line failure is NOT set to OFF. Check the fuses to
the frequency converter
ALARM 38, Internal fault
It may be necessary to contact your GE supplier. Some typical alarm mes-
sages:
0 Serial port cannot be initialized. Serious hardware failure
256-258 Power EEPROM data is defect or too old
512 Control board EEPROM data is defect or too old
513 Communication time out reading EEPROM data
514 Communication time out reading EEPROM data
