WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualified personnel can result in death or serious
injury.
•
Disconnect power before proceeding.
Troubleshooting
•
Remove the power from 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.
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualified personnel can result in death or serious
injury.
•
Disconnect power before proceeding.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period.
Troubleshooting
•
Let the unit cool to operating temperature.
WARNING/ALARM 34, Fieldbus communication fault
The network on the communication option card is not
working.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and
is not set to
[0] No Function
.
Troubleshooting
•
Check the fuses to the frequency converter and
mains supply to the unit.
ALARM 37, Phase imbalance
There is a current imbalance between the power units.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
is shown.
Troubleshooting
•
Cycle power.
•
Check that the option is properly installed.
•
Check for loose or missing wiring.
It may be necessary to contact the GE supplier or service
department. Note the code number for further trouble-
shooting directions.

ALARM 39, Heatsink sensor
No feedback from the heat sink temperature sensor.
The signal from the IGBT thermal sensor is not available on
the power card. The problem could be on the power card,
on the gatedrive card, or the ribbon cable between the
power card and gatedrive card.
WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove the
short circuit connection. Check
and
parameter E-51 Terminal 27 Mode
.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove the
short circuit connection. Also check
parameter E-52 Terminal 29 Mode
ALARM 45, Earth fault 2
Ground fault.
