Fault / Alarm
F0228
Indicates fault in the serial
Telegram communication.
Reception It indicates the equipment stopped
Timeout receiving valid serial telegrams for a
period longer than the setting in P0314.
F0233
This failure indicates that the CAN
No Supply on interface has no supply between pins 1
CAN Interface and 5 of the connector.
F0234 Bus off error detected on the CAN
Bus Off interface.
F0235
CANopen communication error control
Node Guarding/ detected communication error using the
Heartbeat guarding mechanism.
F0236 Fault indicates that the DeviceNet
Idle Master network master is in Idle mode.
F0237 Fault that indicates that one or more
DeviceNet DeviceNet connections timed out.
Connection
Timeout
F0238 It indicates that the inverter received the
Profibus DP command from the Profibus DP network
Interface in Clear master to go into clear mode.
Mode
F0239
It indicates interruption in the
Profibus DP communication between the Profibus
Interface Offline DP network master and the inverter. The
Profibus DP communication interface
went into offline status.
F0240 It indicates fault in the access to the
Profibus DP Profibus DP communication module
Module Access data.
Fault
Quick Parameter Reference, Faults and Alarms
Description Possible Causes
„
Pulse feedback input circuit fault.
„
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 P0314.
„
Disable this function in P0314.
„
Measure if there is voltage within the allowed range
between the pins 1 and 5 of the CAN interface
connector.
„
Check if the supply cables are not misconnected
or inverted.
„
Check for contact problems on the cable or
connector of the CAN interface.
„
C h e c k fo r s h o r t- c i rc u i t o n th e CA N c i rc u i t
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 are with correct
values and have been 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
to exchange messages. 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 the problems in the communications that may
cause missing telegrams or transmission delays.
„
Set the switch that controls the master operation 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.
„
Check the network master status, ensuring it is in
the run mode.
„
Check if the network master is correctly configured
and operating properly.
„
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.
„
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 fault. If possible, carry out tests by replacing the
communication accessory.
