Error messages
The frequency inverters have protection functions against e.g. overcurrent, overvoltage,
undervoltage,... In case of a trip, the output voltage is switched off, the motor stops idle and the
inverter stays in trip state until the trip is resetted.
No. Trip Possible ccause Remedy aactions
E01 Overcurrent or overvoltage of Sudden load spikes, Avoid sudden overloads,
the IPMs in static operation stalling motor, select inverter and motor with
short circuit on the motor terminals, higher power capacity,
earth fault, check motor cable and motor for
nominal motor current is higher than short circuit or earth fault,
nominal current of inverter decrease parameter A045
E02 Overcurrent or overtemperature Set deceleration time is too short, Increase deceleration time,
during deceleration short circuit at motor terminals, check motor cable and motor for
earth fault, short circuit or earth fault,
nominal motor current is higher than decrease parameter A045
nominal current of inverter
E03 Overcurrent or overtemperature Set acceleration time too short, Increase acceleration time,
of the IPMs during acceleration short circuit at motor terminals, check motor cable and motor for
earth fault, short circuit or earth fault,
set voltage boost to high, check the load and starting
stalling motor, torque,
nominal motor current is higher than decrease parameter A042
nominal current of inverter (A242)
E04 Overcurrent or overtemperature Too high ambient temperature Check ambient temperature;
during stand-still decrease parameter A045
E05 Triggering of the int. motor protection Motor overload Select an inverter and motor
with higher power capacity
E06 Overload of braking resistor Duration time of internal braking Increase deceleration time,
unit is too high increase duration time of
braking unit (b090)
E07 DC link overvoltage Set deceleration time is to short, Increase deceleration time,
motor is in generator-mode use a braking resistor,
do not activate AVR during
deceleration, adjust higher
motor voltage (A082)
E08 EEPROM error Above-average high data storage, The life time of the EEPROM
power supply failure during data is about 10000 storages
storage, (related to 10 years with a few
high electromagnetic fields, storages a day)
or too high ambient temperature
E09 Mains undervoltage Wrong mains voltage, Check input voltage
short mains losses
