External alarm via DIx (option “no
external alarm” in P263 to P270).
Alarm that indicates serial
communication fault. It indicates the
equipment stopped receiving valid serial
telegrams for a period longer than the
setting in P314.
It indicates that the CAN interface has no
power supply between pins 25 and 29 of
the connector.
Wiring on DI1 to DI8 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 25 and 29 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.
A134
Bus Off

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.
A135
Node Guarding/
Heartbeat
CANopen communication error control
detected communication error using the
guarding mechanism.
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.
A136
Idle Master
Alarm indicates that the DeviceNet
network master is in Idle mode.
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

DeviceNet connections timed out.
It indicates that the inverter received the
command from the Profibus DP network
master to go into clear mode.
It indicates interruption in the
communication between the Profibus
DP network master and the inverter. The
Profibus DP communication interface
went into offline status.
Check the network master status. Check network installation, broken cable or fault/poor contact
on the connections with the network.
Check the network master status, ensuring it is in the run mode.
Check if the network master is correctly configured and operating
proper l y.
Check for short-circuit or poor contact on the communication
cables.
Check if the cables are not misconnected or inverted. Check if the termination resistors with the right value were
installed only at the end of the main bus.
Check the network installation in general - cabling, grounding.
A140
Profibus DP Module
Access Error
It indicates error in the access to the
Profibus DP communication module
data.
Check if the Profibus DP module is correctly fitted. Hardware errors due to improper handling or installation of the
accessory, for instance, may cause this error. If possible, carry
out tests by replacing the communication accessory.

switch in the saturated (closed switch) and cut-off (open switch) modes.
DC Link: intermediary circuit of the inverter; voltage in direct current obtained by rectifying the power supply
alternate voltage or external supply; it supplies the output inverter bridge with IGBTs.
