Description
Fault in data transfer using MMF
accessory.
Fault related to the automatic
identification algorithm of the inverter
hardware.
External alarm via DIx (option "no
external alarm" in P263 to P270).
External fault via DIx ("no external fault"
in P263 to P270).
It indicates that the device stopped
receiving valid telegrams for a period
longer than the setting in P314.
The time counting starts as soon as
it receives the first valid telegram, with
correct address and error-checking
field.
It indicates that the CAN interface has
no power supply between pins 25 and
29 of the connector.
Bus off error detected on the CAN
interface.
CANopen communication error control
detected communication error using
the guarding mechanism.
Alarm indicates that the DeviceNet
network master is in Idle mode.
Alarm that indicates that one or more
DeviceNet connections timed out.
Analog input signal AI1 at 4 to 20 mA
or 20 to 4 mA is below 2 mA.
Alarm to replace the fan (P045 >50000
hours).
Indicates that the drive is in Fire Mode.
It indicates that the device stopped
receiving valid telegrams for a period
longer than the setting in P314.
The time counting starts as soon as
it receives the first valid telegram, with
correct address and error-checking
field.
Possible Causes
Attempt to download data from the flash memory module to
the inverter with the inverter energized.
Attempt to download a SoftPLC application incompatible
with the destination inverter.
Problems saving data downloaded to the inverter.
Poor contact in the connection between the main control
and the power pack.
Hardware not compatible with the firmware version.
Defect on the internal circuits of the inverter.
Wiring on DI1 to DI8 inputs are open or have poor contact.
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.
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.
Current signal on the analog input AI1 interrupted or null.
Parameterization error on analog input AI1.
Maximum number of operation hours of the heatsink fan
exceeded.
The digital input programmed for activating the Fire Mode is
active.
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.
