Fault/Alarm
F0072: The motor overload protection has
Motor Overload tripped.
Note:
It can be disabled by setting
P0348 = 0 or 3.
F0074: A ground fault occurred either in the
Ground Fault cable between the inverter and the
motor or in the motor itself.
Note:
It can be disabled by setting
P0343 = 0.
F0078: Fault related to the PTC temperature
Motor sensor installed in the motor.
Note:
Overtemperature
- It can be disabled by setting
P0351 = 0 or 3.
- An analog input and an analog
output must be set for the PTC
function.
F0080: Microcontroller watchdog fault.
CPU Watchdog
F0084: Auto-Diagnosis Fault.
Auto-Diagnosis Fault
A0090: External alarm monitored through a
External Alarm digital input.
Note:
It is necessary to program a digital
input for "No external alarm".
F0091: External fault monitored through a
External Fault digital input.
Note:
It is necessary to program a digital
input for "No external fault".
A0098: General Enable signal is missing
Activate General during the self-tuning.
Enable
F0099: The current measurement circuit is
Invalid Current presenting an abnormal value for null
Offset current.
A0110: Fault detected through PTC type
High Motor temperature sensors installed in the
Temperature motor.
Note:
- It can be disabled by setting
P0351 = 0 or 2.
- An analog input and an analog
output must be set for the PTC
function.
A0128: It indicates that the inverter stopped
Serial receiving valid telegrams during a
Communication certain period.
Note:
Timeout
It can be disabled by setting
P0314 = 0.0 s
F0150: Overspeed fault.
Motor Overspeed It trips when the actual
speed exceeds the value of
P0134 x (100 % + P0132)
than 20 ms.
F0151: FLASH Memory Module (MMF-01)
FLASH Memory fault.

Possible Causes
The settings of P0156, P0157 and P0158 are too low
for the used motor.
There is excessive load at the motor shaft.
Short-circuit to the ground in one or more output
phases.
Motor cable capacitance is too large, resulting in
current peaks at the output.
Excessive load at the motor shaft.
Severe duty cycle (too many starts / stops per minute).
Too high surrounding air temperature.
Loose connection or short-circuit (resistance < 100 Ω) in
the wiring connected to the motor thermistors.
Not installed motor thermistors.
Blocked motor shaft.
Electrical noise.
Defect in the inverter internal circuitry.
Firmware incompatible with an accessory.
A digital input (DI1 to DI8) programmed for "No external
alarm" is open.
A digital input (DI1 to DI8) programmed for "No external
fault" is open.
The digital input programmed for "General Enable"
is open.
Defect in the inverter internal circuitry.
Excessive load at the motor shaft.
Severe duty cycle (too many starts / stops per minute).
Too high surrounding air temperature.
Not installed motor thermistors.
Blocked motor shaft.
Check the wiring and the ground installation.
Make sure that the inverter has sent a new message
within the time interval set at P0314.
Wrong settings of P0161 and/or P0162.
Problem with a hoist-type load.
Defective FLASH memory module.
Check the connection of the FLASH memory module.
