Fault
Possible Causes
Diagnose & Remedy
F0005
Inverter I
2
T
● Inverter overloaded.
● Load duty cycle too high.
● The motor power rating (P0307) is
greater than that of the inverter (r0206).
● 100 % overload reached
● Does the load duty cycle lie within the
permissible limits?
● Use a motor with a lower rating (motor power
P0307 is greater than inverter power r0206)
F0011
Motor overtemp. I
2
T
Motor overloaded
● Is the load cycle correct?
● Is the thermal motor time constant (P0611)
correct?
● Is the motor I
2
t alarm threshold correct?
F0035
Restart fault after n
attempts
P1210 (Automatic restart) is enabled and
restart attempts have been conducted for
more than three times.
Set P1210 = 0 (Disabled)
F0041
Failure, motor data
identification
Motor data identification run unsuccessful
● Is the motor connected to the inverter?
● Is the motor data in P0304-P0311 correct?
● Is motor circuit configuration correct (star, delta
configuration)?
F0051
Parameter EEPROM
Fault
Read or write operation while saving
parameters in the EEPROM was
unsuccessful.
● Reset to factory setting and then re-parameterize
● If the fault remains, contact your local distributor
F0052
Power stack fault
Read error, power data or invalid power
module data
Contact your local distributor
F0055
Operator panel
EEPROM fault
Read or write failure while saving non-
volatile parameter to EEPROM on the
operator panel whilst parameter cloning.
● Re-upload parameters
● Replace the operator panel
F0056
Parameters
downloading failed
Fail to download parameters whilst
parameter downloading
Re-download the parameters
F0057
Fail to saving
parameters into the
operator panel
● Parameter cloning with empty operator
panel
● Parameter cloning with invalid operator
panel
● Re-upload the parameters into the operator panel
● Replace the operator panel
F0058
Incompatible contents
saved in the operator
panel
Try to do the parameter cloning with the
operator panel installed on another type of
inverter
● Download the parameters from an inverter with
the same frame size
● Re-configure the settings of motor data, P0611,
P0640 and other necessary parameters
F0060
Asic time slice
overflow
Internal communication failure/error
Contact your local distributor
F0070
Internal
communication error 1
No setpoint was received internally
Contact your local distributor
F0071
Internal
communication error 2
No setpoint was received
Contact your local distributor
