Possible Causes
Overload on the motor shaft.
Inverter output overcurrent.
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 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 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.
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 value
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
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.
