Current imbalance
Current imbalance between the phases. Restart the motor and
check the mains currents and voltage.
Current underload
The motor current has fallen below the warning level. Check that
the motor current parameter (Ie) is set correctly.
Fan failure
One or several fans are not working properly. Risk of overheating.
Contact ABB sales office for service.
EOL warning
The motor is nearly overloaded because of too high current over a
certain time. Check starting conditions and EOL settings.
Locked rotor
The motor current has exceeded the warning level. The motor is
running stiff. A damaged bearing or a stucked load could be pos-
sible causes. Check the load and the motor.
Over voltage
The main voltage is nearly out of range (x - x V)
Under voltage
The main voltage is nearly out of range (x - x V)
Power factor underload
The power factor has fallen below the warning level.
THD(U)
THD has exceeded the warning level. Check quality of the network.
Thyristor overload
The calculated thyristor temperature has exceeded the warning
level. Check the starting conditions and the fans. Increase current
limit if needed.
Voltage imbalance
Voltage imbalance between the phases has exceeded the warning
level. Check the mains voltage.
Short circuit
There is an internal short circuit and the softstarter is running in limp
mode. Contact ABB sales office for service.
EOL time-to-trip
The predicted time before EOL trip has fallen below the warning
level.
Phase loss
Voltage to one or more phases missing. Check that the mains are
connected and that no line contactor or breaker is open.
