Warnings and Alarms
Troubleshooting
•
Check parameter B-15 Brake Check.
ALARM 29, Heatsink temp
The maximum temperature of the heat sink is exceeded.
The temperature fault is not reset until the temperature
drops below a defined heat sink temperature. The trip and
reset points are different based on the frequency converter
power size.
Troubleshooting
Check for the following conditions.
•
The ambient temperature is too high.
•
The motor cables are too long.
•
Incorrect airflow clearance above and below the
frequency converter.
•
Blocked airflow around the frequency converter.
•
Damaged heat sink fan.
•
Dirty heat sink.
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from 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.
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.
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 35, Option faultOut of frequency range
An option alarm is received. The alarm is option-specific.
The most likely cause is a power-up or a communication
fault.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and parameter SP-10 Line
failure is not set to [0] No Function.

Troubleshooting
•
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
Table 10.5 is shown.
