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 digital
External Fault input.
Note:
It is necessary to program a digital input
for "No external fault".
A0098: General enable signal is missing during
Activate General the self-tuning.

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 certain
Communication period.
Timeout Note:
It can be disabled by setting
P0314 = 0.0 s
A0133: It is the alarm indicating that the power
CAN Interface supply is missing at the CAN controller.

Description Possible Causes
„
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.
„
Broken or disconnected cable.
„
The power supply is turned off.
„
Incorrect communication baud rate.
„
Two network slaves with the same address.
„
Wrong cable connection (inverted signals).
„
Communication problems.
„
Wrong master configuration/settings.
„
Incorrect configuration of the communication
objects.
„
PLC in IDLE mode.
„
PLC command register bit set to zero (0).
„
One or more allocated I/O connections have
entered the timeout state.
„
Verify the network master status, making sure it is
in the execution mode (Run).
