• Supply voltage below the mini-
mum allowed value.
• Insufficient input power to power
the device.
Reset mode:
• Automatic reset if parameter Au-
torestart = ON
• Check the value of the power supply voltage both under no
load and load conditions.
• Verify that the source has enough power to power the load.
A06 Over

flashing.
The power supply voltage or the
voltage inside the device exceeds
the maximum allowed value.
Reset mode:
• Automatic reset if parameter Au-
torestart = ON
• Check the value of the power supply voltage both under no
load and load conditions.
• Check for regeneration from the load.
• Increase parameter Ramp down
• Increase parameter Ramp freq. min motor
• In the case of a permanent magnet motor, check that the load
is not subjected to passive movement.
A07 Max
value
alarm
7 flashes of the
yellow alarm led
The value read by the analog input
is higher than the value set for the
parameter Max alarm value.
Reset mode:
• Automatic reset
• Check the value set for the parameter.
• Check the hydraulic causes that lead to the alarm condition.
• Check that the sensor is working properly.
A08
Locked
rotor
2 flashes of the
yellow alarm led
The automatic frequency limitation
created by the inverter following an
excessive absorption by the motor
(beyond the value set in the param-
eter Rated motor current) causes
a reduction of the frequency below
the average value between Min mo-
tor frequency and Max motor fre-
quency.
Reset mode:
• Alarm reset by STOP key.
• Disconnecting the power supply
• Check the possible solutions for the alarm A01 Overcurrent
motor
A09
Overload
inverter
5 flashes of the
yellow alarm led
The current absorbed by the load
exceeds the rated current of the de-
vice.
Reset mode:
• Alarm reset by STOP key.
• Disconnecting the power supply
• Check that the rated current of the motor is lower than the
rated current of the device.
• Make sure that the motor is free to rotate and check for any
mechanical issues.
• Increase the value of the parameter Ramp up time.
• Increase the value of the parameter Ramp freq. min motor.
• Adjust parameter Voltage boost
• Check the value of the power supply voltage both under no
load and load conditions.
CAUTION
The device can supply power to the load for
10 minutes at a current consumption of 101 %
of the rated current of the device, and for 1
minute at a current consumption of 110 % of
the rated current of the device.
A10
IGBT trip
alarm
5 flashes of the
yellow alarm led
The current absorbed by the load
instantaneously exceeds the maxi-
mum current protection of the devi-
ce's power module.
Reset mode:
• Automatic reset after 10 seconds
for up to 3 attempts, after which
you must wait for 60 minutes.
• Disconnecting the power supply
• Check the possible solutions for alarms A01 Overcurrent motor
and A09 Overload inverter.
• Check for short circuits between the output phases and the
ground insulation.
• Check that the system is properly grounded.
• Check for electrical noise from other devices connected to the
system.
A11 No
load
Yellow alarm
LED on and
alarm display via
App.
The current absorbed by the load is
too low in relation to the parameter
Rated motor current.
Reset mode:
• Alarm reset by STOP key.
• Disconnecting the power supply
• Check the possible solutions for the alarm A01 Overcurrent
motor
