Fault / Alarm
A046 Motor overload alarm.
Motor Overload
A050 Overtemperature alarm from the power
Power Module module temperature sensor (NTC).
Overtemperature
A090 External alarm via DIx (option "No
External Alarm External Alarm" in P26x).
A128 Alarm that indicates serial communication
Telegram Reception fault. It indicates the equipment stopped
Timeout receiving valid serial telegrams for a period
longer than the setting in P314.
A133 It indicates that the CAN interface has no
No power supply on the power supply between pins 1 and 5 of
CAN interface the connector.
A134 Buss off error detected on the CAN
Bus Off interface.
A135 CANopen communication error control
Node Guarding/ detected communication error using the
Heartbeat guarding mechanism.
A136 Alarm indicates that the DeviceNet
Idle Master network master is in Idle mode.
A137 Alarm that indicates that one or more
DeviceNet Connection DeviceNet connections timed out.
Timeout
A163 Analog input signal AI1 at 4 to 20 mA or
Signal Fault AI1 20 to 4 mA is below 4-20 mA.
A700 No communication with remote HMI, but
Remote HMI here is frequency command or reference
Communication Fault for this source.
A702 This failure occurs when there is a
Inverter Disabled SoftPLC movement block (REF block)
active and the "General Enable"
command is disabled.
A704 It occurs when 2 or more SoftPLC
Two Movem. Enabled movement blocks (REF Block) are
enabled at the same time.
A706 This failure occurs when a SoftPLC
Refer. Not Prog. SPLC movement block is enabled and the
speed reference is not programmed for
the SoftPLC.
A712 It occurs when there is an attempt to
SPLC protected against copy the SoftPLC application protected
copy against copies.

Possible Causes
Settings of P156 is too low for the used motor.
Overload on the motor shaft.
High temperature at IGBTs (P030 > 110 °C).
High ambient temperature around the inverter (>50 °C (> 122 °F))
and high output current.
Blocked or defective fan.
Heatsink is too dirty, preventing the air flow.
Wiring on DI1 to DI4 inputs are open or have poor contact.
Check network installation, broken cable or fault/poor contact
on the connections with the network, grounding.
Ensure the master always sends telegrams to the equipment
in a time shorter than the setting in P314.
Disable this function in P314.
Measure if there is voltage within the allowed range between
pins 1 and 5 of the CAN interface connector.
Check if the power supply cables are not misconnected or
inverted.
Check for contact problems on the cable or connector of the
CAN interface.
Check for short circuit on the CAN circuit transmission cable.
Check if the cables are not misconnected or inverted.
Check if all the network devices use the same baud rate.
Check if the termination resistors with the right specification
were installed only at the end of the main bus.
Check if the CAN network was properly installed.
Check the times set on the master and on the slave for message
exchange. In order to prevent problems due to transmission
delays and time counting, it is recommended that the values
set for error detection by the slave be multiples of the times set
for message exchange on the master.
Check if the master is sending the guarding telegrams in the
time set.
Check problems in the communication that may cause missing
telegrams or transmission delays.
Set the switch that controls the master operation of the master
for Run or the corresponding bit on the configuration word of
the master software. If further information is needed, refer to
the documentation of the master used.
Check the network master status.
Check network installation, broken cable or fault/poor contact
on the connections with the network.
Cable of AI1 broken.
Poor contact at the signal connection on the terminals.
Check if the communication interface with the HMI is properly
configured in parameter P312.
HMI cable disconnected.
Check if the drive General Enable command is active.
Check the user's program logic.
Check the programming of the references in the Local and/or
Remote mode (P221 and P222).
Attempt to copy WLP application protected against copies
("never permit copies").
Attempt to copy WLP from a copy protected against copies
("no permission to copy from a copy")
