Inverter alarm table
E06:3
The inverter bus voltage is unsteady
around the nominal value
check the power supply voltage
(120V / 208-240V /480V AC). If necessary
replace the inverter.
E06:4
the inverter bus voltage has dropped
below the minimum allowable
check the power supply voltage
(120V / 208-240V /480V AC)
E06:5
the inverter bus voltage has raised up to
the maximum allowable
check overvoltage from the power supply (120V
/ 208-240V /480V AC)
or from the motor ( 100- 240V AC )
E06:6 The inverter is not able to turn the motor
check that the motor is free to move. Check that
the three phases are connected to the motor.
E06:7
Motor overload
check that the motor is free to move and doesn’t
touch any other item
E06:8 Excessive heating of the dissipater
Verify cooling fan of the electric compartment,
Verify cooling fan inside the inverter if it is clean
and works properly
E06:12 The output current too high
check that the motor is free to move and doesn’t
touch any other item
E06:13
Found leakage currents too high
between one of the phases and earth.
check that one or more phases of the motor or of
the power supply wires are not short circuited to
the ground/frame
E06:33 Automatic restart failed
There was an alarm 3, 4, 5, 6, 7, 8, 12, 63 or 64,
but the automatic restart was unsuccessful.
Remove the cause of these alarms and restart.
E06:38 Phase U short circuited to GND
check the correct connection of the motor and
check that the phase U of motor supply is not
short circuited to the GND
E06:39 Phase V short circuited to GND
check the correct connection of the motor and
check that the phase V of motor supply is not
short circuited to the GND
E06:40
Phase W short circuited to GND
check the correct connection of the motor and
check that the phase W of motor supply is not
short circuited to the GND
