Description
Buss off error detected on the CAN
interface.
CANopen communication error control
detected communication error using the
guarding mechanism.
Analog input signal AI1 at 4 to 20 mA or
20 to 4 mA is below 4-20 mA.
No communication with remote HMI,
but here is frequency command or
reference for this source.
This failure occurs when there is a
SoftPLC movement block (REF block)
active and the "General Enable"
command is disabled.
It occurs when 2 or more SoftPLC
movement blocks (REF Block) are
enabled at the same time.
This failure occurs when a SoftPLC
movement block is enabled and the
speed reference is not programmed for
the SoftPLC.

Possible Causes
„
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.
„
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).
